Hello,

I am trying to a do a displacement vs frequency (I know this is doable in GUI, but I want to try the usablility of APDL-Snippet) plot in workbench harmonic responce with APDL-Snippet.

This is the snippet I am using. It seems that there is no erro after runing the snippet. However I don't get any plots by this snippet. Is there anything wrong with this script?

regards

Hi

The PLVAR and NSOL are /post26 commands (not post1 like the apdl snippet we get in Mech.) and we also need to create an image (/show command) for each plot in order to view the result.

As an example for say node nr. 1608:

 

 

 

 

/POST26
NSOL,10,1608,U,Z
/SHOW,PNG
PLVAR,10
/SHOW,CLOSE
/POST1

 

 

 

All the best
Erik

Hi

So you need to be in post26 see below (pay attention to /psot26 and then back to /post1)

/POST26
NSOL,10,1608,U,Z
/SHOW,PNG
PLVAR,10
/SHOW,CLOSE
/POST1

Hi Erik,

I tried as sugessted the following snippet: (I took the node 100)

this time I got an erro-message:

I am not sure, if it is becuse if the node number (actually I tried different). But  definitivly have more than 100 nodes

Hi

The commands I sent work and produce an image of the plvar result – Clear generated data and solve again. If there is an error again ir is related to something else.

See the solution information object (or solve.out file in project file directory) as it says in the error above , and search for errors in that file and see what it is.

All the best
