Solid_Calculation of stresses

[Marta-Neu]

The calculation of the stresses with linear solid elements (hexa8) gives completely wrong results compared to abaqus.

@Marta-Neu I would suggest to check the ContinuumElement3D class with CellType Hexa8. The separate class of the Hexa8 is obsolete and will be removed from the solution in the next release.

@Marta-Neu I would be happy to help you. Please provide me with the nodal coordinates of the hexahedral element and the loading conditions so that I can check the results. In addition, do you know the specifics of abaqus Hexa8 integration you used? Because many abaqus elements use reduced integration or hourglass control and thus may provide different results from the fully integrated hexahedral element.
