Cylindrical CS for applying loading was created by Michal Nytra
Hello people,

I would like to ask you, if there is possible to apply forces in cylindrical CS. I mean for example to apply radial force onto edge of inner wall of pipe.

Thanks for replies.

Regards, Michal Nytra

Hoi Michal

I have been using a RBE3 type of connection to apply a torque on a cylinder, see:
caelinux.org/wiki/index.php/Contrib:KeesWouters/bc/rbe3

Maybe also interesting:

Interest: structural mechanics, solar energy (picture at 'my location' shows too little pv panels)

Hello,

so I can use something like this, that mean define edge of cylinder as GROUP_NO, extract nodes from it, get its coordinates X and Y, calculate alpha=atan2(Y,X) and put it in FORCE_NODALE asi ANGL_NAUT(alpha,0,0).

Hello,

I am sorry, but I don't understand it very well. I am not good in Python and I don't know where to write this code, in *.comm file?

Regards, Michal
