W5c2f1240

Unable to compute centroid for Space/Mask … - using bounding box center instead

A “corrupt” STL/PLY file was supplied for a Mask named in the warning text. Depending on other mask settings (whether the surface is to be used / filled), different centroids / centers of gravity are computed. This warning indicates all those attempts have failed and instead the bounding box center is used.

This can happen if the input has degenerate triangles or is not a closed surface. Please check the input files or replace these if possible.

Please contact MSC Apex Generative Design support for further help.

We7ec7c46

The number of maximal used GPUs (solverUsedGpuMax) is higher than the number of available GPUs.

If you are using the Command Line execution, adjust the number of solverUsedGpuMax and Restart the optimisation. Otherwise the optimisation will continue with less GPUs.

W1c9c8673

Not enough memory available.

The model is too large, complexity is too high for this optimisation model.

Adjust the Complexity and try a new optimisation run.

W1d175302

No volume greater than 50% found!

The optimisation model is insufficiently designed. The solver cannot find a satisfactory solution.

This can be a hint that the STL-file format is incorrect for a Restart or Start Space optimisation. It’s also possible that the input STL-file is defect. Please check the unit system and the quality of the input STL-file.

Another reason for this error can be an unsupported filename. There cannot be spaces, parenthesis and accents in the names – except for the SolidWorks STL-files. SolidWorks produces a specific name which our engine supports and is able to read.

The software supports binary STL-files and almost all ASCII files but not faultless.

For further questions please contact MSC Apex Support.
