when the UMESHMOTION subroutine is switched on and job is submitted, the job gets aborted immediately. i am doing a wear simulation problem with two bodies have a relative reciprocating motion with a pressure load. please help me to solve the issue.

 

[FEA way]

Does the analysis converge without the subroutine ? If yes then it seems that your subroutine works in such way that it causes convergence issues. Can you check the results generated before the analysis aborts ? Do they look correct ?

pls check the attached results

What I meant is that you should take a look at the results (in odb file) generated in this analysis with subroutine before it aborted. You may notice some incorrect deformation of the mesh caused by UMESHMOTION.

the result obtained after job getting aborted is attached. I couldn't see any abnormal deformation to mesh. the log file is also attached

Is that deformed shape plot with scale factor = 1 ? Did you try using finer mesh ?

 

[Ajith Kurian Baby]

yes, the plot was with a scale factor 1 and tried with increased mesh density for lower body but, still it gets aborted in the same manner. I tried with much reduced load it also didn't work.

in Umesh subroutine, I was trying to execute different call functions one by one, without any other conditions or statements
call GETVRN(NODE,'V',VEL,JRCD,JGVBLOCK,LTRN)
call GETPARTINFO(NODE,0,PARTNAME,LOCNUM,JRCD)
call GETNODETOELEMCONN(NODE,NELEMS,JELEMLIST,JELEMTYPE,JRCD,JGVBLOCK)
call GETVRMAVGATNODE(NODE,'CSTRESS',ARRAY,JRCD,JELEMLIST,NELEMS,JMATYP,JGVBLOCK)

I found that when the fourth call function is called, the job is getting aborted. if I avoid that and run code without any other statements or conditions job is running.
