Hello everybody,
I simulate quasi static tasks within Radioss. Models that I use cannot be meshed with hexa(design is too complex) but the quality of linear tetra isn't sufficient. Parabolic tetra seems reasonable solution, but I faced crashes with different control types, for CST, for example, it is spontaneous mass growth in contact area(always in the middle nodes). Does anybody have experience with such issue? Any tips regarding usage of parabolic elements?
Regards,
Ivan
