Hello, everyone.

I'm having a really hard time currently trying to export the results of mid-side nodes using APDL. As I understand it, the results are evaluated at the Gauss integration points, then interpolated at the corner nodes. The mid-side nodes are the average of the two corner nodes. When I probe, the result is there, but when I export, usually the corner node results are correct, and the mid-side nodes are empty.

I have tried using AVRES, 1 and ERESX, YES, as well as PRNSOL, S, EQV

The code has this base:

/POST1
SET, LAST
ALLSEL, ALL
/GRAPHICS, POWER
/EFACET, 2
AVRES, 1
AVPRIN, 0, 1
ERESX, YES
CMSEL, S, Nodes
*GET, n_count, NODE, 0, COUNT

*DIM, node_ids, ARRAY, n_count

*DIM, vm_stress, ARRAY, n_count

 

curr_node = 0

*DO, i, 1, n_count

    curr_node = NDNEXT(curr_node)

    node_ids(i) = curr_node

    *GET, vm_stress(i), NODE, curr_node, S, EQV

*ENDDO

 

I have tried a few different approaches, but I never manage to export the values at the mid-side nodes, which I know exist due to the probe tool returning me results. I wanted to avoid having to "manually" calculate the average between two corner nodes. Does anyone know if it's actually possible, and if so, how to export these results? Otherwise I think I might just use only corner nodes instead. 

Thanks for reading
