I have now found a way but I don't know if there is a easier way.
My steps to get the rotational FRF are:
- Create a remote point on the point of the part where you need rotational displacement
- Add the following APDL command to the remote point
- Create an APDL command in the solution of the harmonic response (RS).
(Since I need the frequency range from 0 to 4000 Hz and the solution itervalls are 1000 I do this through a script)
*cfopen,'rot_z_FRF','txt' ! create a text file
*do, i, 1, 1000 ! the solutions intervalls from the analysis settings
*vwrite, my_freq, my_rot_z
How can I read the value of the solutions intervalls automaticly from the analysis settings?
