BlasMolero: thanks a lot :)

There is one more thing. Can you tell me where I can find the element library for NX Nastran, and its analysis types?

Thanks for thorough reply. So, the conclusion is, that I have to use common 4 node elements...?

Thanks BlasMolero, for quick response :) I am trying to solve a simple box (100x100x100 mm with 5 mm thick wall), with pressure on one side, and fix BC on the opposit side. It's a testing job, for a much complex calculation of reservoir with internal pressure. I tried to use the plane strain...

Hi! I am trying to conduct a nonlinear analysis with shell elements. Is there a way, how to do that with parabolic shells? With, linear elements everything works nicely, but with parabolic elements results is same as results from standart static analysis. Can anyone help me? please

Hi Guys! I have a similar problem. Is there a way, how to export plastically deformed model in to another analysis? So don't use elastic deformation. For example flange deformed by pretensioned bolt, and then by inner pressure and elevated heat. Or is there any other way how solve this kind of...

Try to check coincident nodes (tools - check - coincident nodes) , and then look to free edges (F5). In the static analysis, the model behaves properly???

Ofcourse I want :) Where is this file, with contact?

Yes, I'm form Czech. rep. Why? Yes, you are correct about my model. Applied BC: - force on piston - Then there are a rigid elements in one bearing (surface spider node)and this node is fully fixed in cylindrical Csys (z - axis of shaft). This node is on axis of shaft. - On this node made by...

Hi, thx for reply. It's crankshaft of turbocompressor, and the force is applied on piston. So whole assembly is connected together by contacts and modeled by solid elements, so it doesn't have 4,5,6 DOF. And i chose SOL601, because I need contacts and I need solution in time (one rotation of...

Hi! Please, is there anyone who can help me with this issue? I am using SOL601, with contact set to "glued" everything works nicely, but with regular contact this error appear: ***WARNING: No element connection for node 2 directions 4, 5, 6 ***WARNING: Similar warning suppressed for...

I forgot to write that will be Contact.

Hello everybody, I need help with my recent analysis. I need to perform rotation of shaft with one force applied analysis. The Shaft has to rotate about it's axis about 360 degrees. Only one force is aplied in this shaft. Can anyone tell me which analysis do I have to perform? Any other advices...

Hello, you won't. To calculate stiffness, you will need Young's modulus, and cross section of solving part. If you are able to find the solution for your situation then you have to calculate stiffness accordingly to analytic solution of simplified model. For example, for simple tension /...
