RAFilterProcess

class RAFilterProcess

PrePost Scripting wrapper for Property Processes.

IterCellVertices(cell: int, time_step: str | int | ITimeStep = 'current')

Iterate on the vertices of active grid cells at the given time.

Parameters:
- cell_handle – The cell handle
- time_step – Either a ‘current’ string with meaning the current time step or an ITimeStep identifying the time to iterate the vertices of a cell or an int identifying the time step index to be used based on the global time set
Return type: vertex_handle
Returns: The iterator over all the cell’s vertices.

IterCells(time_step: str | int | ITimeStep = 'current')

Iterate on the active grid cells at the given time.

Parameters: time_step – Either a ‘current’ string with meaning the current time step or an ITimeStep identifying the time to iterate the cells or an int identifying the time step index to be used based on the global time set
Return type: iterator
Returns: The iterator over all the active grid cells for the given time.

IterParticles(time_step)

Iterate on particles in this selection at the given time. Only for processes created on Particles.

Parameters: time_step (unicode , ITimeStep or int) – Either a ‘current’ string with meaning the current time step or an ITimeStep identifying the time to get the topology shape or an int identifying the time step index to be used based on the global time set
Return type: iterator(Particle)
Returns: An iterator over the particles. A Particle has:
- x, y, z, size
- x_axis, y_axis, z_axis, orientation_angle
- type, particle_group

Modified(*args, **kwargs)

SetCurrentTimeStep(time_step)

Sets the current time step.

Parameters: time_step (ITimeStep) – The time step to be considered the ‘current’ time step.

SetCutValue(value, unit=None)

Sets the single, exact value by which you want the property results limited when Type is Value

Parameters:
- value – float The new cut value
- unit (str *|*None) – The unit of the given value or None if given the same unit already used

SetMaxValue(value, unit=None)

Sets the highest value by which you want the property results limited when Type is Range

Parameters:
- value – float The new maximum value
- unit (str *|*None) – The unit of the given value or None if given the same unit already used

SetMinValue(value, unit=None)

Sets the lowest value by which you want the property results limited when Type is Range

Parameters:
- value – float The new minimum value
- unit (str *|*None) – The unit of the given value or None if given the same unit already used

SetMode(property_mode)

Parameters: plane_mode – ‘Cut’ or ‘Select’ Sets whether the property process is selecting or cutting the cell’s from the input process

SetPropertyGridFunction(grid_function, realization=None)

Set the grid function which this property process will use to filter its input elements

Parameters:
- grid_function (unicode) – The new grid function
- realization (unicode) – An additional keyword to identify the curve realization

SetType(filter_type)

Parameters: filter_type – ‘Value’ or ‘Range’ Sets whether the property process filters elements that match a specific value or a range of values
