Hi
I hope it is fine for you I am replying in English.

If you are using tetrahedral element, the property setting depend first on the type of tetra elements you are using:

• Tetra10 are more accurate but more expensive and you should set Itetra10 = 2 in the property; I also recommend you to add /DT1TET10 engine option in your engine file (0001.rad)
• If using Tetra4, then set Itetra4 = 3

Regarding other formulation setting such as Ismstr parameter, I suggest to use first automatic settings (Ismstr = -1, Icpre = -1)
