It looks like you are running into the same problem as in this post: [Stresses from ANSYS .rst are displayed as NaN](https://discourse.paraview.org/t/stresses-from-ansys-rst-are-displayed-as-nan/13836)

A quick summary: your data has quadratic elements. The tetrahedra have 10 values: 4 for each vertex and 6 for each edge. Some of your fields (e.g., `Nodal Solution 0`) have values for all 10 control points. However, other fields (e.g., `Mises`) only have values for the 4 vertices. The values for the edges are set to 0, which messes up the quadratic interpolation in the cell. The easiest solution is to set the `Nonlinear Subdivision Level` display parameter to 0.
