Hello, I'm trying to do some calculations on Wind overturning stability on a self supported cone roof tank with internal pressure. The thing is that when I look at the design code in the point 5.2.1(k)2 it states the maximum design pressure on roof. My struggle is to understand the meaning of...
Hi, I just wanted to get your opinion and insight about the subject. I know a drop test of an empty bottle can be done easily with SOL 601/701, but what happens if the bottle is filled with a fluid? I'm unable to find an easy answer as how to model this problem using NX Nastran. Any idea of how...
Hi, I wanted to know if it is possible to create plain strain elements in NX or if I just need to edit the .dat file and replace the name of the element. Anyone knows?
I'm trying to learn how to make a two way iterative coupling on NX Nastran with the solver SOL 601. In the modeling guide it says It can be done in the chapter 9 but it is quite vague.
So far I realized I have to include the TRANOPT parameter in the TMCPARA entry. The COUP parameter for the...

I have advanced nonlinear solution 601 in the solver options but Im going crazy trying to find out what to do to do the real multi-physics coupling. I'm able to do nonlinear plasticity problems but dont see anywhere how can I include thermal solution or restrictions or anything. Is it done in NX...
Hi Blas thank you for your quick answer. I already did the thing you told me here without a problem but my question was if it was possible to do a coupled iterative coupling as its described in NX Nastran 8 Advanced Nonlinear Theory and Modeling guide (page 355 to 360)
"! In iterative coupling...
Hi, I'm working in NX 8.5 and going crazy trying to make a coupled thermo-mechanical analysis. In the documentation (I believe it is in the advanced nonlinear modeling guide) It says the solver has the option to use TMC that is thermal coupling, and has several options. But I dont seem to find...
Just another question, in the meantime I'll check the files you mention and if I find it ill post it so some other people in the same situation as me understands. In the example you mentioned I have two questions. When you specify the thickness as 0. it doesn't have problems when the solution...
Hi blas, Thank you for your quick answer. As I understand I have to mesh the surface with 2d meshing and set a material like if it were an elastic one. But when I define the contact and set the region as rigid and then select the master grid point the software automatically connect all the nodes...
Hi, I am trying to make a simple exercise of using two rigid bodies(tools) to make a plastic deformation in some kind of part. It would be a fixed rigid die and a rigid tool that pushes the steel piece to the die. I searched everywhere on how to make a body rigid in advanced simulation and I...
