Re: Conjugate Heat Transfer problem in CFX for a rotating domain
For a Conjugate Heat Transfer CHT) problem involving fluid-solid coupling through a fluid-solid interface, and if on the fluid side of the interface the wall is a counter-rotating wall, you would set the rotating wall condition under the fluid side of the interface (located in the tree outline under the fluid domain) under Boundary Details.

Re: Ansys Insight: Convection on Surface Body
One method is to use a beta option in WB:
In WB, Tools --> Options --> Mechanical --> Scroll down and check "Thermal Variation (beta)" beta option. Restart WB for this option to take effect.
In the details of the surface body, you can select "Thermal Variation (beta)" option and also use an option for Convection to be applied on Top or Bot of the face.
Because you use different temperatures at top and bottom surfaces, you will need to extract temperature with user defined results. TTOP is temperature at top surface. TBOT is temperature at bottom surface.

Re: [Mechanical Workbench] Huge viewfactor file creating problems in radiation study
I don't know about viewfactor, but many ANSYS analyses requires large amounts of free disk space while the solver is running. Large being hundreds of GB.
I recommend you install a second SSD of at least 512GB that is labeled SCRATCH, which is not used to store anything but the current analysis job.

Re: SpaceClaim- When I click anywhere on the window, it disappear immediately
Open stand-alone SpaceClaim, then click on File -> SpaceClaim Options -> Advanced -> Renderer. This is default to Direct3D11, you can try changing to others and see if any of them helps. Make sure you close and restart SpaceClaim after applying the change.
Also, try updating your graphics driver.

Re: How to define a periodic piecewise function for inlet velocity in UDF
I've done this using a mix of IF statements, sin(t) and floor https://www.programiz.com/cpp-programming/library-function/cmath/floor I'll leave you to work out the maths!

Re: Strain in Deformation Analysis course: Importable Engineering Data missing from the zip file
Hello Niklas,
Thank you so much for bringing this to our notice. We have fixed the issue and if you download the zipped folder again, it should include the xml file with all the material data. Then you can import the engineering data and there would be no need to define those materials manually.
Thank you again! Hope you enjoy the course and find it useful!

Re: How to make a mesh so that it does not have negative volume?
The CFD solvers work to double precision, although 75microns is still quite narrow for those. I've done this in Fluent Meshing, but the method is more advanced than I'm allowed to discuss on here. However I can hint, and it involves creative use of the inflation tools.
