Thank you very much Kevin, I will test it tomorrow !

I was thinking of changing my Dirichlet conditions with the transient, but I don't see how to do it. I want to block nodes for a period of time and release the blocks afterwards. In other words, I want to apply 1 boundary condition only for the first steps. Boundary Condition 1 Target Boundaries(2) ...

Thank you Kevin for your reply. In the past, I've done a study following your suggestion (loading for a x acount of time and let it go), and I works well. I could see the damping of the structural part. But now the problem is different, I will do it whitout restart like this : 0 <time < t : - loadin...

Hi all, I have a simple question about loading to a restart from the solution. First, I have mechanical results from a previous compute (strain,stress,dispacement), carried out in step 1. Second, I'd like to restart from the last step of these results with new boundaries : no specific loading, only ...

Thank you Peter for your quick answer.
So I undertand that to rotate a part from a hole, in my case, I have to use BC of Dirichlet on the nodes

hi Kevin, Your answer helped me in the daming test (in the case of : Force in B, blocked in A), the results suit me very well. Now, and it's my last request : I want to apply a tangential force in A in order to rotate the part. Until now, I used displacement conditions on the boundaries, and all is ...

Thank you Kevin.
Your answer suits me well.

hi all, In the past, I had simulated a simple mechanical test using a rotating part (see mesh.png: rotary movement in A, blocked in B). Now I would like to add an impulse in A, free in B. I would like to see the behavior of the part in B with an impulse. First, I'm thinking of adding a spring at B i...

Thank you Kevin for your quick reply

Hi all, I'd like to know how the number of DOF is calculated with the "element=p:2"option. For example, my mesh contains : 1530 nodes 820 boundaries (type 202) 2242 triangles (type 303) My res file has : displacement : 10606 5303 2 : nonlinear elasticity I don't understand how number 5303 ...
