Unusual Meshing visual display

[ByrnePM]

I am modeling a flat slab structure supported on slabs and walls as is shown in image 1, (not all walls are modeled yet)

I am trying to run a model generation for the walls that I do have modelled at the moment and I have managed to run the calculations without any warnings or errors BUT there is an unusual visual display problem with the mesh on some of the walls ...see image two

Has anyone experienced this before?

If I delete the mesh for the structure and re-mesh it then this unusual curved mesh goes away, however when I run the calculation model the mesh re-appears ?

You need to freeze the mesh. Push that button.

try selecting some of these mesh finite elements and then find the panel to where they belong (click on bar selection , change it to panel  and choose " finite element" as the attribute. Click on the upward arrow and your panel  will be selected ).

delete this panel.
