[FAQ]

There may be two reasons that may lead to this error message: 1. Element nodal stress is not stored in the model. Issue “outres,strs,all” to store stress. 2.One is using high order element and node at which result is needed is a mid node. When using quadratic elements, the stress values are only reported at the corner nodes (and are themselves extrapolated values from the integration points internal to the element). The values at midside nodes are actually just averages of the adjacent corner node values but are not stored. Midsize node can be extracted with command /efacet,2 and prnsol,s, comp
