Dear all, How to export Stress gradients from rst? I need to export stress gradients for surface nodes in my model. Is there any APDL script available for that? I created named selection for set of nodes. For that named selection for each node towards the depth of 1mm surface normal direction, I need to extract stresses and export it into text file..

You could map stress to a path and then use pcalc,deri to compute the gradient along the path.  prpath output can be redirected to a file.

Is it possible to share the script if available for small set of nodes? I need APDL commands to map stresses in the path...

set,last       ! store results

lpath,pick   ! pick nodes in direction desired

pdef,seqv,s,eqv  ! or other stress quantity

pcalc,deri,seqvd,seqv

prpath,seqv,seqvd
