Re: missing stress values Sxy, Syz, Szy

Hello! Be careful with the shear stresses. Sxy, Syz, Szy... Calculix .frd file contains stress components per node. Calculix .dat file contains stress components per element. But the order of them is different (different indexes...) ! This is discussed here... https://forum.freecadweb.org/viewtopic....

Re: Display principal stresses

To sum up, are sxz and syz components exchanged? I think you are right that components are written in a different order. I don't exactly recall where it was discussed, if somewhere on this forum or on the ccx mailing list. Response from cxx mailing group https://groups.yahoo.com/neo/groups/calculix...
