In RF- / DYNAM Pro, I get the error message: "The assigned mass case does not exist," although I have defined a mass case. What is the reason for this?


Before you can start the calculation in the add-on module, you should check each tab. This message appears if you have not opened the calculation parameters of the natural mode case at least once. Although a bulk case has been defined, it has not yet been assigned to the natural mode case.
