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.
