If your model includes beam elements (runners or cooling channels) connected to 3D Tetrahedral elements:
: If the clock difference is too large between the client workstation and the license server, FLEXlm will reject the license checkout. Ensure your network time protocols are synchronized.
Moldflow uses RAM first, but for large 3D meshes, it spills over into the Windows page file (virtual memory). If your page file is set to a fixed size (e.g., 16GB) and Moldflow needs 32GB, the allocation fails, and you get Error 99998. autodesk moldflow error 99998 full
