Known Issue

Workaround or Solution

SpaceClaim rendering does not manage depth. When displaying Light Expert rays, the XMP results are displayed first and in front of the rays, therefore hiding the rays. (TFS 971064 SF 68035 68390)

Hide the XMP result and show the sensor in the 3D view.

CPU Simulation with Single Ray tracer precision generates unexpected results when the source support and the first geometry seen by the source are the same size. (TFS 917398)

Make sure to define a size of the source support different from the size of the first geometry seen by the source.

Simulation is not compatible with a named selection (group of geometries) containing one or several faces of a surface body. (TFS 888268) You must select the surface body to use the named selection in the simulation.
As a result of an Inverse Simulation using a Camera Sensor or an Irradiance Sensor when the Light Expert is activated, rays generated using the Gathering algorithm are not integrated in the *.lpf result. Therefore few rays may appear in the *.lpf result. However all rays are correctly integrated in the XMP result. (TFS 646080)
Local Meshing: the Meshing can be wrong when the Step value applied is smaller than the face size. (TFS 552272 551166 551355) Check the meshing quality using Preview Meshing and adjust if needed.
When the Automatic Compute is activated for an Interactive Simulation, the Preview Meshing on geometries is not available. (TFS 279412) Deactivate the Automatic Compute.
Canceling a Monte-Carlo Inverse Simulation does not create intermediate result in the Simulation tree. (TFS 451371)
Using special characters in feature names prevent simulations from running correctly. (TFS 378374 SF 31224)

Inverse simulations can take more time than expected when several sensors are involved. For a simulation with Y sensors and X time stopping criteria, the simulation may take X * Y time to run. (TFS 338429)

Trying to open a new session of Speos while computing a simulation does not work. (TFS 202650 - SF 25120)

Selecting geometry groups containing a lot of items might cause the software to freeze. (TFS 210096)
