Dear Sir / Madam,

I am working on the parametric design of single-stage 2D Tesla Valve on CAESES and further optimisation on ANSYS Workbench.

I managed to follow the guide and imported .FSC file from CAESES via CAESES Geo Engine from ACT. 

It successfully transferred to workbench with parameter set appeared, and I proceeded to Spaceclaim and WB Meshing.

But it doesnt show 2D option (locked in grey) when launching FLUENT. A error message "exception of type 'ansys.fluent.cortex.cortex unavailable exception' was thrown" popped up if I insist running it in 3D setting. 

Grateful if you could provide some guidance or insights on this. Thanks so much!

 

Best Regards,

Jason

Hello,
Please check if the path to the environment variables is set correctly and you are importing the file from the right path. Thanks!

What are your domain extents? Is the green axis label y? 

[Jason Sum]

Thanks Nilay and Rob for the answers. I coped with above issue!

However, as the analysis proceed, though I managed to do the meshing and solving on FLUENT for the base case with default values of the parameters input from CAESES.

Once I set the ranges for every input parameters and ran the Design of Experiment to see the changes in the output parameter (i.e. outlet flowrate), the output values for all design cases are the same. 

I am thinking if the changes made in input parameters did not actually alter the geometry, as the geometry on spaceclaim doesnt change when I alter its parameters.

Tesla valves seem all the rage lately!

Do you have an inlet pressure and an outlet pressure boundary condition defined, or do you have the outlet boundary condition as as a mass-flow-rate?

[Rob]

Unfortunately as it's a third party tool I can't test. DesignModeler (Ansys geometry) has similar functionality in terms of parameters if CAESES isn't updating SpaceClaim correctly. The only comment I can make on CAESES is that it's referenced in the Optislang manuals in a few places, but I suspect that's overkill for what you're doing, and it's not in the Student bundle. 

All yours Nick! ;)

Hello, I would like to know how you solved this problem, I used caeses for parametric modeling and had a similar problem.My model can't be updated after it's imported into Workbench.
