I want to add a fluid region with STL file. In initial->Fluid Regions->Add a fluid region. Then choose "Use functions coefficients for" "STL Geometry". Then click "change" to choose my STL file. But when I run the preprocess simulation, Something error happened. The error message is "Abnormal exit from preprocessor" and
"processing fluid initialization regions
processing cad data for fluid region 1
"
How can I solve this problem.

Run the model with coarse mesh and this issue will be gone.
