Hi Jiapeng, You would create a trimesh collision shape, based on a ChTriangleMeshConnected object. I added the ability to read a ChTriangleMeshConnected<https://api.projectchrono.org/classchrono_1_1geometry_1_1_ch_triangle_mesh_connected.html> from an STL file a few months ago (see ChTriangleMeshConnected::CreateFromSTLFile and ChTriangleMeshConnected:: LoadSTLMesh), so you can only do this with the latest code in the ‘main’ branch of the Chrono git repository.

If I import two triangular meshes based on two *.stl files. Can I do contact detection between these two meshes? Which "shape" object should I use to import these two *.stl files?
