Hi Everyone,

I'm attempting to gather nodal forces off MPC184 elements using the FSUM command for Response Spectrum and Random Vibration analyses. I'm using APDL snippets that are identical to those I've used before, but while using ANSYS 2022 R1 (student), I am continually getting the error:

"The .MODE file does not exist for the calculation of the sum of the nodal forces. The FSUM command is ignored."

Has anyone encountered this error? I've set ALL of my relevant analysis settings to "Yes" to make sure I'm not losing any files along the way.

Thanks in advance!
