Export nodal strains with mixed materials without averaging in APDL

      Hello,nI have a 2D model in Workbench with different materials, of which I exported an APDL input file. I edited the input file so I can export all the nodal eqv strains to a txt file. However, since some nodes are shared by two materials, I get the following warning:nn *** WARNING *** CP = 1.203 TIME= 15:36:24n The selected element set contains mixed materials. n This could invalidate error estimation. nnFurthermore the averaging of the two strains on one node increases the wall-time for one simulation considerably. Therefore I would prefer the script to output two different strain values for one node to the txt-file and skip the averaging. Is there a method to achieve this?.Script for txt export:nn/post1n*get, _nsteps, active,,solu,ncmlsn! set,last,last ! Set to last time stepn*get,_nrNodes,NODE,0,count !

      You need to access the element results. You can print them using PRESOL. You can also store them using an ETABLE and the *GET the results from the ETABLE.n
