PSD constraint force output in random analysis


Hello,
is it possible to have as output a PSD of a constraint force on a single node in
a random analysis?
Thanks

Marco,
Yes this is possible. In the case control, include lines like this

OUTPUT(XYOUT)
XYPLOT SPCF PSDF/ 2475 (T1), 2475 (T2), 2475 (T3)
XYPUNCH SPCF PSDF/ 2475 (T1), 2475 (T2), 2475 (T3)

Here we are requesting SPC force resultant output at node 2475 in the x, y, and
z directions. XYPLOT will write the result to the OP2 file. XYPUNCH writes it to
a punch file.

Re: PSD constraint force output in random analysis


Thanks (late) for the answer. By the way, in the same way, is it also possible to
extract as output the PSD of an interface force between two groups of elements,
while you are applying a PSD acceleration load on one of these two groups?
Thanks
