Cylindrical BC for RADIOSS
Altair EmployeeHi everybody,
is it possible to assign a Radioss' BCs to a cylindrical system?

Altair EmployeeHi 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.
Altair Employeeit 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.
Altair EmployeeHi Luke,
Based on the loading conditions in the model, I made slight modifications. Can you check the model attached along.
Altair Employeenow 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?

Altair EmployeeHi 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?
Yes. it does not support the cylinder constraint so far, you have to resort to the radioss /impdisp in a workaround way as above post guided.
I asked it because it seems that the assignment to a cylindrical skew didn't work for my simulation in Radioss.
