Number of Stress Results vs. Number of Nodes about pymapdl HOT 6 CLOSED

What you're seeing is the stresses at only edge nodes as ANSYS does not store strain and stresses at midside points

If you still need the stress at the mid side nodes, since ANSYS does store displacements for its midside nodes, if you knew the shape functions of the element, you could evaluate the stress at the midside nodes. It might be easier to interpolate using polyharmonic splines based on the stresses at edge nodes.

Thanks for the quick answer!
Is there a possibility to get the assignment of node and output stress value easily?

No problem!

The trick is to use the stored edge index self.edge_node_num_idx in the result object. Here's a snippet from the source:

# Initialize stress array for all nodes
stress = np.zeros((self.resultheader['nnod'], 6))

# Populate with nodal stress at edge nodes
stress[self.edge_node_num_idx] = self.NodalStress(rnum)

Where self is the result object.

Thanks! Worked well!

There is. This is a separate issue. Could you open a new one?
