Force Reactions in Random Vibration / Response Spectrum Analysis

      I'm getting the attached error message when trying to pull a Force Reaction from a Fixed Support in a Random Vibration & Response Spectrum analysis in Ansys Mechanical.

      Anyone know what's causing this?

      In the precursor modal analysis, did you set the "Nodal Forces" output to "yes"? If not, that probably needs to be changed, solution re-run for modal and then the random vibration analysis.

      I found out what was causing it. I was also getting another error that stated "Invalid characters were detected in the project and/or environment name". I had a & character and spaces in the .wbpj project name. I took those out and that fixed it. I am now able to pull Force Reactions from Fixed Supports in a Random Vibration & Response Spectrum analysis.
