So I got mainly 2 problems.

The first problem is that i cannot use the /CWD, 'path' command, because every time i try to include it to my code it will show me an error.

My main task is it to analyse the same model but with different forces. These forces I apply with the F, 100, FY, -10000 command for example.

After every applied force i want to save data to txt-documents, e.g. the deformation or the stress. Therefore I use these commands:

set,lastplns,s,XY
*get,numnode,node,,count
*dim,nd_sig1,array,numnode
*vget,nd_sig1(1),node,,s,XY
*cfopen,'s XY','txt'
*vlen,1
*vwrite,'Nodal','s XY'
(A8,X,A8)
*vwrite,sequ,nd_sig1(1)
(F8.0,X,E13.6,X,E13.6)
*cfclos

But there is one problem; to get this data I have to wait for the /post1 command and after this command the program stops, so the question is, whether there is a way to apply a force to the model, then go to the postprocessing (/post1), and then go back to the next force and so on.

This is my intial idea, at the SOLVE command I would like that the program goes to the postprocessing (to the apdl command that are in the file, which is executed after the /post1 command):

*DO, i, 600, 650, 1
 F, i, FY, -100000
 /CWD, 'C:UsersalexaDesktopwork_gnrl_numwork1_filesdp0SYSMECH'
 /SYP,mkdir ,'force%i%'
 /CWD, 'C:UsersalexaDesktopwork_gnrl_numwork1_filesdp0SYSMECHforce%i%'
 SOLVE
 F, i, FY, 100000
 
*ENDDO

I thank you in advance
