Question:
In RF‑/DYNAM Pro, I get the error message: "The assigned mass case does not exist", although I have defined a mass case. Why?
Answer:
Before you start the calculation in the add-on module, we recommend checking all tabs. This message appears if you have not opened the calculation parameters of the natural mode case at least once. In spite of having defined a mass case, it has not yet been assigned to the natural vibration case.
