Barre and POU_D_E mix

In 1D, pin joints(DX,DY,DZ=0) are represented by Barre and rigid joints(DX,DY,DZ,DRX,DRY,DRZ=0) by POU_D_E.
For example, A model in which one of the beams is a pin joint and the other is a rigid joint.
How should we express a structure that conbines these two ?

Re: Barre and POU_D_E mix

Bonjour.

Have a look of the book of the geat and beloved Jean-Pierre Aubry : framabook.org/beginning-with-code_aster/

Read chapter 7.2 and look how the hinge are treated.

you can model pin by DIST_TR element witk K_TR_D_L stiffness properties. You have to put a 0 stifness where you want rotation.

Re: Barre and POU_D_E mix

Thank you for your reply

I made a similar model using Framabook, but I got an error. Do you know what's wrong with the command file?

I succeeded with only POU_D_E, but when I inserted the hinge, I got an error.
