Hmm. My apologies. The expression "moment of inertia" isn't exactly the best. I'm not native english speaker and sometimes I have problems with some expressions. However, I was talking about second moment of area:
We usually call this one moment of inertia, which is not the same as mass moment...
Thank you very much Drej, I think I found the problem.
It is like this. I did tests with both 3 and 6 DOF (with changing KEYOPT(1)). And the first problem was, that normals were not consistent. Some were directed outside and some inside. And I never saw that because I was always doing...
OK, so as far as I understand your answer it is not very good idea to use this SECOFFSET in my case at all.
Actually that test that I did was with flat surfaces, not with some irregular shapes. And when I plotted those shell elements, I saw that they were "offset" from the nodes, but the...
Oh, I'm sorry for incomplete description.
The reason for offseting the nodes is that this shell, if I can call it like that, is bonded to the part which is modeled with solid (SOLID185) elements.
The geometry is taken from CAD package (and meshed in ICEM CFD), hence, I don't have midplane of...
Hello!
I have a question regarding to the use of command SECOFFSET in connection with element SHELL181 that I use for linear structural analysis.
I'm using this element to model shell with few layers, but I need to offset nodes from midplane to the top or bottom of the element.
The problem is...
