poICFD SetStreamLineDecimation

Specifies whether decimation should be applied to the streamlines in the CFD Plot/Streamlines panel, in order to reduce the memory footprint.

Syntax

poICFD_handle SetStreamLineDecimation decimation_on

Application

HyperView Tcl Modify

Description

This command specifies whether or not to apply decimation to the streamlines obtained by the integration process. Decimation will effectively reduce the memory footprint and improve graphic performance afterwards, however it is important to note that the streamlines could become less smooth and decimation process itself takes some time. After decimation is turned on, you can further specify decimation criterion based on max break angle, max speed variation, and max line segment length by calling the following commands: SetMaxBreakAngle, SetMaxSpeedVariation, and SetMaxLineSegmentLength.

Inputs

decimation_on: The boolean value turning decimation on or off.

Example

To turn the streamline decimation "on":

hwi OpenStack
hwi GetSessionHandle session_handle
session_handle GetProjectHandle project_handle
project_handle GetPageHandle page_handle [project_handle GetActivePage]
page_handle GetWindowHandle window_handle [page_handle GetActiveWindow]
window_handle GetClientHandle client_handle
client_handle GetModelHandle model_handle [client_handle GetActiveModel]
model_handle GetResultCtrlHandle result_handle
result_handle GetCFDCtrlHandle CFD_handle
CFD_handle SetStreamLineDecimation true
hwi CloseStack

Error

Returns false if no integrator exists.
