I am having trouble performing a modal analysis in ANSYS APDL (unfortunately I am not familiar with most of the commands yet, therefore using the GUI).
I am importing a solid188 beam model (including its mesh) which I created in workbench.
I am then following the commands as decribed in this explanation to do a modal analysisand get the free vibration modes: http://www.ansys.stuba.sk/html/guide_55/g-str/GSTR3.htm
However, when I want to view the results file, I get an error saying that the results file could not be written because there are no active degrees of freedom.
Could anyone help with this? Thank you!
