Cylindrical BC for RADIOSS

I asked it because it seems that the assignment to a cylindrical skew didn't work for my simulation in Radioss.

Hi Luke,

RADIOSS doesn't support to assign boundary conditions in a cylindrical coordinate system now. But to work on it, you can select the nodes and put imposed displacement (/IMPDISP, and keep icoor=1),for each dof with zero magnitude function.

it didn't work. I gave a displacement in the radial direction and my geometry moves in the z-direction, even if I asigned all nodes and loads to the local system that I want. Morever, the resulting movement is also strange if i consider the global coordinate system. Here the model attached.

Hi Luke,

Based on the loading conditions in the model, I made slight modifications. Can you check the model attached along.

now the direction are correct. What modifications do you make?

Moreover I changed the direction of the IMPDISP along the X direction (by changhing the 'y_scale' from 1 to -1) and during the simulation contacts are deactivated. why does this happen?

Hi Luke,

Did you constrain the upper component in X direction?. Also review the interface created.

Does radioss still dont support assigning BC in cylindrical coordinate?
