Boundary conditions in ansys

Boundary conditions in ansys

Boundary conditions in ansys

(OP)
Hai,

   I have a complex model in which cylindrical surfaces and planar surfaces are present.

  I have to apply few boundary conditions on cylindrical surfaces(Cylindrical co-ordinate system) and few boundary conditions on planar surfaces(cartesian co-ordinate system).

Therfore in the same model, boundary conditions applied based on both cylindrical as well as cartesian co-ordinate system.

I am using Ansys package.

The current procedure I am following is for the

1) For the cylindrical surfaces, I rotated corresponding nodes about the cylindrical co-ordinate system.Then applied boundary conditions related to cylindrical co-ordiante system.

2)Then for the boundary conditions on planar surfaces, I created local cartesian co-ordinate system. I activated the local cartesian co-ordiante system into active co-ordiante system. I applied boundary conditions on the planar surface with respect to this local cartesian co-ordinate system.

Whether the above procedure is right? If not please correct the procedure.

 My understanding about boundary condition is, Boundary conditions with respect to nodes are very important.If the boundary conditions looks reasonable about the nodal co-ordinate system,then it is ok.

Regards,
elogesh
