Reply To: Determining the stress where maximum strain occurs

[Erik Kostson]

Hi
and There is not easy way without some scripting for doing what you need and also being able to do this for any model, so it is a generic process, which is what one wants - please see the psevdo-script below and try and implement that:

(APDL commands in APDL or as a APDL command snippet in Mechanical)
Set results to look at SET,LAST,LAST (takes the last solved time to look at)
Use *get to get maximum nodes (say called: my_NCOUNT) in the model (*GET, my_NCOUNT, NODE,,COUNT)
*do, to loop over nodes and obtain the maximum strain and at which node (say called my_nmaxEPTE) this occurs
Finally issue *get to get the maximum stress at the node found in previous loop, e.g., the VM stress there would be: *GET,my_nmaxS,NODE, my_nmaxEPTE,S,EQV
the result my_nmaxS will show up and we can use it as an output parameter also.
This is all about 9 lines of codes so not to difficult to implement.
Search the forum, the internet and the help manual for more info on *GET and *DO and *IF/*ENDIF.
