Hello everyone,

i'm new in the APDL scripting. 
I only need the stress tensor of the node with the maximum equivalent stress, as txt output. 

This is the APDL-script:

/POST1            !First postprocessing step

/com, ########### Postprocessing #########

/com, ########### Maximum equivalent stress - global cartesian  #########
/SHOW,PNG    !Show plot. Required to show plot in workbench
SET,LAST        !Specify last time step for post-processing

/output,Max_EQV_and_Tensor,txt               !Open a text file titled Max_EQV_and_Tensor

/com, ########### Postprocessing #########

/com, ########### Maximum equivalent stress - global cartesian  #########

PLNSOL,S,EQV             !Plot nodal solution for equivalent stress
*GET,NODENUM,COMMON,,CPOST1,,INT,108           !Get node number of node with the max value in previous

/com, #### stress tensor - solution cartesian ####
RSYS,solu                        !Activates a coordinate system for printout, Solution coordinate system

NSEL, S, NODE, ,     <----- there is the problem. How can i select the node of the maximum equivalent stress or the node of the last *GET command?

prnsol, s, comp                  !Prints nodal solution result, components of the Stress tensor

/output,term

Now, the post-solver writes every node in the txt-file, but i only want that one node with the above written information.

Thanks for help. I hope you can help me.

 

Here is the outputscript:

ok, i got it. Post closed, i have to write after NSEL, S, NODE, ,   <— the node name “NODENUM” …. simple things but waste time ?
