simulation_instanceansys.api.speos.scene.v2.scene_pb2.Scene.SimulationInstance, optional: Simulation instance to provide if the feature does not have to be created from scratch By default, None, means that the feature is created from scratch by default.
default_valuesbool: Uses default values when True.

name (str)
description (str)
metadata (Optional[Mapping[str, str]])

SimulationInverse.set_geom_distance_tolerance(value=0.01)#

Set the geometry distance tolerance.

Parameters:

valuefloat: Maximum distance in mm to consider two faces as tangent. By default, 0.01

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_max_impact(value=100)#

Define a value to determine the maximum number of ray impacts during propagation.

When a ray has interacted N times with the geometry, the propagation of the ray stops.

Parameters:

valueint: The maximum number of impacts. By default, 100.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_weight()#

Activate weight. Highly recommended to fill.

Returns:

ansys.speos.core.simulation.BaseSimulation.Weight: Simulation.Weight

SimulationInverse.set_weight_none()#

Deactivate weight.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_colorimetric_standard_CIE_1931()#

Set the colorimetric standard to CIE 1931.

2 degrees CIE Standard Colorimetric Observer Data.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_colorimetric_standard_CIE_1964()#

Set the colorimetric standard to CIE 1964.

10 degrees CIE Standard Colorimetric Observer Data.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_dispersion(value=False)#

Activate/Deactivate the dispersion calculation.

Parameters:

valuebool: Activate/Deactivate. By default, False, means deactivate.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_splitting(value=False)#

Activate/Deactivate the splitting.

To split each propagated ray into several paths at their first impact after leaving the observer point.

Parameters:

valuebool: Activate/Deactivate. By default, False, means deactivate.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_number_of_gathering_rays_per_source(value=1)#

Set the number of gathering rays per source.

Parameters:

valueint: This number pilots the number of shadow rays to target at each source. By default, 1.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_maximum_gathering_error(value=0)#

Set the maximum gathering error.

Parameters:

valueint: This value defines the level below which a source can be neglected. By default, 0, means that no approximation will be done.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_ambient_material_file_uri(uri='')#

To define the environment in which the light will propagate (water, fog, smoke etc.).

Parameters:

uristr: The ambient material, expressed in a .material file. By default, "", means air as ambient material.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_stop_condition_passes_number(value=5)#

To stop the simulation after a certain number of passes.

Set None as value to have no condition about passes.

Parameters:

valueint, optional: The number of passes requested. Or None if no condition about passes. By default, 5.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_stop_condition_duration(value=None)#

To stop the simulation after a certain duration.

Set None as value to have no condition about duration.

Parameters:

valueint, optional: Duration requested (s). Or None if no condition about duration. By default, None.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation

SimulationInverse.set_automatic_save_frequency(value=1800)#

Define a backup interval (s).

This option is useful when computing long simulations. But a reduced number of save operations naturally increases the simulation performance.

Parameters:

valueint, optional: Backup interval (s). By default, 1800.

Returns:

ansys.speos.core.simulation.SimulationInverse: Inverse simulation
