Hello,
Currently I am working on a problem that considers both NLADAPTIVE and element deletion command snippets in Mechanical. Unfortunately NLADAPTIVE does not support EKILL commands for element deletion. For that reason I would like to delete elements via the EDELE command. As this command is only valid in the /prep7 processor, I have to switch processors between loadsteps. The model consists of a gradually increasing displacement over multiple loadsteps.
The problem I encounter when using the EDELE command in combination with ANTYPE restart is that the subsequent loadstep is considered loadstep n=1 (start at initial loading condition), while this should be n+1 (continue loading conditions).
I'm fairly new in writing my own commands, so I would like to learn how to properly deploy a restart for a subsequent loadstep that takes into account the adjustments (element deletion) made in the /prep7 environment in order to continue the simulation with the new mesh. Help is greatly appreciated!
Kind regards,
Paul
Hi Paul van Houten
I was wondering if you specify the STATUS of ANTYPE as restart.
- ANTYPE, Antype, Status, LDSTEP, SUBSTEP, Action, --, PRELP
You should specify Status and Action as RESTART and continue respectively.
Hello Seyed Morteza Hoseyni ,
Thank you for the response. I have indeed set the ANTYPE settings as you described. This works, but does not take into account the /prep7 commands I wrote before the ANTYPE (/solu) command. If I enter the /prep7 after, I get the issue of not restarting properly as described earlier. Am I able to make adjustments in the /prep7 processor after the ANTYPE command?
