I am consistently encountering the following error during simulation setup:
“Slit facet body – There exist laminar triangle facet edges inside the face geometry. This usually happens when the triangulation is not conformal (matching vertices) or vertex precision is bad, e.g., when importing STL files.”
I have attempted to resolve the issue by importing the geometry into Blender and applying a 30° Edge Split operation before exporting the file as STL. Despite this preprocessing, the same error persists in SimScale.
Without looking at the model, it is a bit tricky to comment whether you will be able to resolve CAD issues using our CAD mode or would have to fix them in your preferred modeling tool.
Feel free to share a link to your project and share it with support (if it’s private) so we can take a closer look. You can simply go to the part of the simulation with the issue and copy the URL of your browser at that time and paste it here.
