Hello, everybody,

I must say in advance that I am at most an advanced beginner in the topics CAD and FEM, which is why I would like to apologize in advance for wrong terms and gaps in understanding.

My problem is very trivial: I want to have an FEM calculation carried out in Ansys for different geometries of a certain structure. Put simply, the geometry consists of two cylinders with different diameters placed on top of each other, with one cylinder merging into the other over a radius. I hope the geometry is understandable, otherwise I'll send you a drawing.

It is now possible for me to parameterize the two diameters in Spaceclaim and to run a simulation over the parameter space. What I currently still fail with is the transition radius: In the previous simulation this was assumed to be fixed, but in reality it is the difference between the two diameters. Can this simple equation (R = D2 - D1) be defined as a function somewhere?

Thank you very much

Hi lux88,

In Workbench, within Parameters, you can use Expressions. That means that you can put P2 as a function of P1. In SpaceClaim you can also use the Ruler tool to set parameters as distances from given references.

Doing this, I receive this error:

 (DP 0) Update of the Solution component in Modal for Design Point 0 failed: Error updating cell Solution in system Modal.

Although it works perfectly fine by typing in values manually in Spaceclaim.

Can you please insert images with some description with arrows. 

As ANSYS Engineer, we are not able to download attachments.

Here some images:

1. My Geometry with 5 Parameters. R is defined in workbench as "D2 - D1"

 

2.

 

3.

The solution for only 2 design points. Point 0 works good with the initial geometry of the CAD-File. DP 1 results in this error.

 The images are very blur. I can not see error clearly. Can you please insert some zoomed in images.
