Paul_Re is on a distinguished road
I have the following set up:

Toolbox: Geometry
-> Design Modeler: 1 Part, 1 Body (23 Faces, 22 Edges)
-> 1 Inputparamter: Angle

Fluid Flow (CFX)
-> Mesh: Automatic Mesh of the Body
-> Setup: 1 Inlet and 3 Outlets
---> 1 Inputparameter: massflow
-> Results: Simulation works!! So i have results!
---> 1 Outputparameter declared


The parameter set shows these Parameters. In the Table of Design Points i have choosen some different angles, but here starts my problem. CFX does not calculate solutions for this different angles (input parameter).

I get always the message "error updating cell mesh in system..".

I declared for a test in the mesh generator the body as an parameter, i even dont know the function of this but i didnt helped.

So i think cfx takes the different angles of the geometry as inputparameters and tries to make the specific mesh, but there is might be not the right adjustment.

Doing the same manually: adjusting the angle in the geometry-> updating the mesh -> updating the setup ---> This works ...

Do i have to consider some special options?
Or is in the mesh generator something to adjust?
Or do i have to change the drawing/model in the design modeler. that there must be a special part oder body for this?
Or, or ... ?

So everybody, thanks for any help!
Paul
