Parametric Model with Design Modeler and ICEM
 

Hi everyone,

I've been silently reading on this forum for a while now and I have to thank you for all your support so far. Now I myself have a problem, for that I can't seem to find the solution:


I am modelling a axisymmetric flow through a cavity between a rotor and a stator. The geometry is fairly simple and completely symmetric. Therefore I modeled the cavity in the Design Modeler and defined parameters for the Geometry (e.g. Diameter, width, Extrusion angle etc.) and meshed it in ICEM.

When I only do small changes to certain parameters, my model seems to work just fine. The association of the blocking in ICEM works perfectly.
But if I change a parameter drastically, the diameter for example, ICEM seems to confuse the association of the geometry. This results in a completely unusable mesh. As I Previously mentioned, my geometry is simple and nothings changes but the dimensions of the Geometry itself, so the total amount of vertices,edges etc. stays the same.


So my question ist: What do I have to do to make my model truly parametric, even with big parameter changes?

Kind regards,
Maurice
