Parameters: filename (str, pathlib. Note: If the project has an External Data system that consumes files stored within the design point path and multiple design points, updating the multiple design points can cause the project to fail or produce inaccurate data. The unprocessed commands are represented by the IGenericCommand. PyPrimeMesh Does not recognize this command and ignores this. Conditionally causes commands to be read from a specific block or at a specific location. Welcome to the Command Reference. I have a spring that deflects under a sinusoidal motion.
