Meshing errors when importing AMIGA CAD model into Fusion/ANSYS for simulation

Hello, we are currently using the official AMIGA CAD files for simulation in Autodesk Fusion and ANSYS, but we are encountering repeated geometry-related meshing errors during surface and solid mesh generation. The model imports correctly, but mesh creation fails, likely due to detailed features such as wheel treads or small components. Has anyone experienced similar issues, and is there a simplified or simulation-ready version of the CAD available? Any recommendations on preferred export formats or geometry cleanup steps would be greatly appreciated.
