extract the maximum value available in the defined table in APDL?

Question

Hello Ansys APDL users, I want to extract the maximum value available in the defined table, how do I do that? Suppose I have this code:

ESEL,ALL             
ETAB,EVOL,VOLU 
SET,50,LAST 
ETAB,EPS50,NL,EPEQ 
SET,32,LAST 
ETAB,EPS32,NL,EPEQ 
SADD,EPS2,EPS50,EPS32,1,-1 
SMULT,EPS_v,EPS2,EVOL,1,1   

Now, I want to get the maximum value in table EPS_v or EPS2, how to get that? When using Ansys in GUI mode, I can simply use the following command to extract the value:

PLETAB,EPS_v,AVG
*GET,EPS_max,PLNSOL,,MAX

But if I am running the simulation in batch mode, I can’t use these commands. Is there any other way I can extract the maximum value from the defined table? Or is there any other way we can save the full table as a text file? Your responses are highly appreciated. Thank you in advance!

Answer 1

You can sort an element table with

ESORT, Item, Lab, ORDER, KABS, NUMB

than take the max item.

In your case that would be:

etable,EPS50,NL,EPEQ
esort,etab,EPS50,1
*get,EPS_max,sort,0,max

Or you could export the etables to a txt file:

*GET,ecount,ELEM,,COUNT
*DIM,EARRAY,,ecount,2    
*VGET,EARRAY(1,1),ELEM,,ETAB,EPS2    
*VGET,EARRAY(1,2),ELEM,,ETAB,EPS_v    
*CFOPEN,ETABLES,txt    
*VWRITE,SEQU,EARRAY(1,1),EARRAY(1,2)
(F10.0,5X,F10.8,5X,F10.8)
*CFCLOSE
