◆ determine_model_time_offset()

void realization::Bmi_Module_Formulation::determine_model_time_offset ( )

protectedinherited

Determine and set the offset time of the model in seconds, compared to forcing data.

BMI models frequently have their model start time be set to 0. As such, to know what the forcing time is compared to the model time, an offset value is needed. This becomes important in situations when the size of the time steps for forcing data versus model execution are not equal. This method will determine and set this value.

void realization::Bmi_Module_Formulation::do_bmi_sets_from_stored_metadata	(	const time_t &	src_data_start,
		const time_step_t &	t_delta )

privateinherited

Set BMI input variables before `BMI update, using saved metadata rather than re-fetching or re-calculating.

This is one of two available execution paths used by set_model_inputs_prior_to_update for the bulk of its behavior. Certain metadata details about a BMI input variable must be available in order for the framework to execute a set_value call: e.g., the data provider that is the correct source of input values, the analogous C++ type, the number of items, etc. In this execution option, that data is obtained once and stored for subsequent reuse, optimizing compute at each time step a bit at the expense of memory.

References to objects containing these details are stored within the bmi_input_var_details vector, populated on the first call to this function. These are actually pointers to objects contained within the known_bmi_input_vars static member variable.

An important consideration is that this function is not strictly safe relying only on guarantees provided by BMI. Nothing within the BMI spec guarantees that, for example, a variable will not change the number of items it contains. It is therefore possible, in general, for stored data to become stale for a properly implemented BMI module. In practice, however, any selected module's implementation details and behavior will be known by the user, so users can elect to only use this execution path for set_model_inputs_prior_to_update when the BMI module itself guarantees such data cannot become stale.

Parameters

src_data_start	The start time (in seconds) to use when retrieving data from the appropriate provider to use for setting the model's variables.
t_delta	The size of the time step over which the formulation is going to update the model, which might be different than the model's internal time step.

void realization::Bmi_Module_Formulation::do_bmi_sets_with_full_refetch	(	const time_t &	src_data_start,
		const time_step_t &	t_delta )

privateinherited

Set BMI input variables before `BMI update, re-fetching and re-calculating required metadata each time.

This is one of two available execution paths used by set_model_inputs_prior_to_update for the bulk of its behavior. Certain metadata details about a BMI input variable must be available in order for the framework to execute a set_value call: e.g., the data provider that is the correct source of input values, the analogous C++ type, the number of items, etc. In this execution option, that data is freshly obtained

either recalculated, redetermined, or refetched from the BMI module itself - on every call to this method. This results in less efficient compute but also reduced memory usage.

An important consideration is that this function provides an execution option that is strictly safe relying only on guarantees provided by BMI. Nothing within the BMI spec guarantees that, for example, a variable will not change the number of items it contains. If a configured module does (or may) change input variable metadata, or if it is possible for a module to change the set of input variables, then this execution path for set_model_inputs_prior_to_update should be selected.

In practice, however, any selected module's implementation details and behavior will be known by the user, so users can elect to only use this execution path for set_model_inputs_prior_to_update when the BMI module itself guarantees such data cannot become stale. better memory and safe for no guarantees

Parameters

src_data_start	The start time (in seconds) to use when retrieving data from the appropriate provider to use for setting the model's variables.

◆ get_allow_model_exceed_end_time()

const bool & realization::Bmi_Module_Formulation::get_allow_model_exceed_end_time ( ) const

overrideprotectedvirtualinherited

Get whether a model may perform updates beyond its end_time.

Get whether model Update calls are allowed and handled in some way by the backing model for time steps after the model's end_time. Implementations of this type should use this function to safeguard against entering either an invalid or otherwise undesired state as a result of attempting to process a model beyond its available data.

As mentioned, even for models that are capable of validly handling processing beyond end time, it may be desired that they do not for some reason (e.g., the way they account for the lack of input data leads to valid but incorrect results for a specific application). Because of this, whether models are allowed to process beyond their end time is configuration-based.

Returns: Whether a model may perform updates beyond its end_time.

◆ get_config_mapped_variable_name()

const std::string & realization::Bmi_Module_Formulation::get_config_mapped_variable_name ( const std::string & model_var_name ) const

When possible, translate a variable name for a BMI model to an internally recognized name.

Translate some BMI variable name to something recognized in some internal context for use within NGen. Do this according to the map of variable names supplied in the external formulation config. If no mapping for the given variable name was configured, return the variable name itself.

For example, perhaps a BMI model has the input variable "RAIN_RATE." Configuring this variable name to map to "precip_rate" will allow the formulation to understand that this particular forcing field should be used to set the model's "RAIN_RATE" variable.

Parameters

model_var_name The BMI variable name to translate so its purpose is recognized internally.

Returns: Either the internal equivalent variable name, or the provided name if there is not a mapping entry.

The values are the model's calculated outputs for the time step; the time step index itself is not included.

Only the last processed time step is accessible, because formulations do not save results from previous time steps; there is thus no valid time step before at least one call to update has been made. Throws std::invalid_argument if timestep is not the current (last processed) time step.

◆ get_response()

double realization::Bmi_Module_Formulation::get_response	(	time_step_t	t_index,
		time_step_t	t_delta )

overridevirtualinherited

Get the model response for a time step.

Get the model response for the provided time step, executing the backing model formulation one or more times as needed.

Function assumes the backing model has been fully initialized an that any additional input values have been applied.

The function throws an error if the index of a previously processed time step is supplied, except if it is the last processed time step. In that case, the appropriate value is returned as described below, but without executing any model update.

Assuming updating to the implied time is valid for the model, the function executes one or more model updates to process future time steps for the necessary indexes. Multiple time steps updates occur when the given future time step index is not the next time step index to be processed. Regardless, all processed time steps have the size supplied in t_delta.

However, it is possible to provide t_index and t_delta values that would result in the aggregate updates taking the model's time beyond its end_time value. In such cases, if the formulation config indicates this model is not allow to exceed its set end_time, the function does not update the model and throws an error.

The function will return the value of the primary output variable (see get_bmi_main_output_var()) for the given time step after the model has been updated to that point. The type returned will always be a double, with other numeric types being cast if necessary.

The BMI spec requires for variable values to be passed to/from models via as arrays. This function essentially treats the variable array reference as if it were just a raw pointer and returns the 0-th array value.

Parameters

t_index	The index of the time step for which to run model calculations.
d_delta_s	The duration, in seconds, of the time step for which to run model calculations.

Returns: The total discharge of the model for the given time step.

inlineprotected

Get a value, converted to specified type, for an output variable at a time step.

Function gets the value for a provided output variable at a provided time step index, and returns the value converted to some particular type specified by the template param.

The function makes several assumptions:

1. `t_index` is a time step that has already been processed for the model
2. `var_name` is in the set of valid output variable names for the model
3. it is possible to either implicitly or explicitly convert (i.e., cast) the output value to the
   template parameter type (or it is already of that type)
4. conversions do not lead to invalid (e.g., runtime errors) or unexpected (e.g., loss of precision)
   behavior

It falls to users (functions) of this function to ensure these assumptions hold before invoking.

Template Parameters

T	The type that should be returned, and to which the BMI variable value should be cast.

Parameters

t_index	The index of some already-processed time step for which a variable value is being requested
var_name	The name of the variable for which a value is being requested

Get value for some BMI model variable at a specific index.

Function gets the value for a provided variable, returned from the backing model as an array, and returns the specific value at the desired index cast as a double type.

The function makes several assumptions:

3. the type for output variable allows the value to be cast to a `double` appropriately

It falls to user (functions) of this function to ensure these assumptions hold before invoking.

◆ is_property_sum_over_time_step()

bool realization::Bmi_Module_Formulation::is_property_sum_over_time_step ( const std::string & name ) const

overridevirtualinherited

Get whether a property's per-time-step values are each an aggregate sum over the entire time step.

This is part of the ForcingProvider interface. This interface must be implemented for items of this type to be usable as "forcing" providers for situations when some other object needs to receive as an input (i.e., one of its forcings) a data property output from this object.

Certain properties, like rain fall, are aggregated sums over an entire time step. Others, such as pressure, are not such sums and instead something else like an instantaneous reading or an average value.

It may be the case that forcing data is needed for some discretization different than the forcing time step. This aspect must be known in such cases to perform the appropriate value interpolation.

For instances of this type, all output forcings fall under this category.

Parameters

Depending on the value of cache_input_variable_metadata (false by default, but which can be controlled using set_cache_input_var_metadata), this will defer most of its execution to a call either to do_bmi_sets_from_stored_metadata or do_bmi_sets_with_full_refetch.

Parameters

model_time	The model's time prior to the update, in its internal units and representation.
t_delta	The size of the time step over which the formulation is going to update the model, which might be different than the model's internal time step.

◆ next_time_step_index

int realization::Bmi_Module_Formulation::next_time_step_index = 0

protectedinherited

Index value (0-based) of the time step that will be processed by the next update of the model.

A formulation time step for BMI types can be thought of as the execution of a call to any of the functions of the underlying BMI model that advance the model (either update or update_until). This member stores the ordinal index of the next time step to be executed. Except in the initial formulation state, this will be one greater than the index of the last executed time step.

E.g., on initialization, before any calls to get_response, this value will be 0. After a call to get_response (assuming 0 as the passed t_index argument), time step 0 will be processed, and this member would be incremented by 1, thus making it 1.

The member serves as an implicit marker of how many time steps have been processed so far. Knowing this is required to maintain valid behavior in certain things, such as get_response (we may want to process multiple time steps forward to a particular index other than the next, but it would not be valid to receive a t_index earlier than the last processed time step) and get_output_values_for_timestep (because formulations do not save results from previous time steps, only the results from the last processed time step can be used to generate output).
