  1. Hello, I'd like to ask why when I trying to request CSTRESS for RANDOM RESPONSE OUTPUTS PSD and RMS I can't find that option in global output request neither subcase output requst ,when it is declared in help that it should be possible. See enclosed pictures:
  2. Hello, -I have solved this problem. -I have used cbush elements with very high stiffness in places where I wanted to measure forces, instead requesting nodal force output. -CBUSH element support PSD and RMS output trough ELFORCE output request.
  3. Hello, I would like to know how to set up PSD nodal force output from RANDOM Response analysis because I have problems with this. I find out it should be possible trough XYPEAK / XYPLOT / XYPUNCH I/O Options and Subcase Information Entry. However, when I use CASE_UNSUPPORTED_CARDS with option e.g. "XYPLOT,FORCE,PSDF / 184934(T2)" where 184934 is ID of grid point in the model, I get following error in .out file: *** See next message about line 13 from file: D:/subory/PHP/Priprava_Modelu_Sendvica/Modalna_analyza/pokus6/Random/test/model_12_5_20__10_26.fem "XYPLOT,FORCE,PSDF / 184934(T2)" *** ERROR # 1651 *** in the input data: Syntax error in XYPLOT/XYPRINT/... card - last item read: "T2". I have also tried use command as follows: "XYPLOT,FORCE,PSDF / 184934(2)" which leaded to error: *** ERROR # 6034 *** Nonexistent element 184934 referenced by XYPUNCH/XYPLOT/XYPEAK request. ************************************************************************ A fatal error has been detected during input processing: *** ERROR # 6034 *** Nonexistent element 184934 referenced by XYPUNCH/XYPLOT/XYPEAK request. which is weird because I would like to see grid/nodal output (no element output). I have also tried use of Tools->Process manager->Freq Resp Process->Random PSD frequency response. Here I don't need to enter the command directly, but trough GUI of process manager which reduces possible mistakes of mine. In the manager I used besides other sections also section "Define Responses"->"Select Nodal PSD Response" where what I need should be possible in my opinion. I used "Add DOFs" where I choose "Response Type: FORCE" and I have selected mentioned node then I choose Y direction and set "Assign Format" to XYPLOT However, eventualy I get same kind of CARD (CASE_UNSUPPORTED) with absolutely same command in it and I get also same error. I have attached model .fem file if it helps. So, I would apreciate if someone can help me. Thank you. model_12_5_20__10_26.fem
