Updated cfmesh.
Installed HiSA-solver via preferences/cfd. Installation ok, dependencies ok.
I want to simulate the openfoam "prism" tutorial with FC (Mach 2 flow along prism)
When writing the case I still get error "compressible model currently not supported"
Maybe my workflow is wrong?

Did you select the "High Mach number" option in the physics panel? This will choose the HiSA solver.

Yes, but I cant write the case.
during Hisa installation there appeared some red lines in the report view,
"Error occurred with cv2pdb, have stripped binary as a workaround"

Those are nothing to worry about.

The error shown in the screenshot was a bug and should be fixed now...thanks for the report.

To be sure: I only update the cfd-wb, no reinstalling of HiSA. correct?
Oliver, many thanks to you and the CSIR-team for providing this
new solver to the community.

:) Case writing ok, HiSA runs.

Hi guys,
I do not know if this fits in here, but I did not want to start a new thread.
I have all tutorials through and am quite familiar with the cfdOF -wb now. Only at the 4th (the UAV tutorial) I can not get on. I did everything as described but I always get an error message and the solver does not expect anything useful (see screenshot).

What I have done:
PhysicsModel: Stady, turbulent case.
FluidProperties: Air
InitialiseFields: Potential flow
openFOAM: parallel true (4), conv.criteria 1e-3, 2000 iterations
Inlet: y = 5m/s and z = -20m/s

Instead of the slice operator I have used XOR (you can see it on the tutorial screenshot as well even if there is written "slice") and it only works with XOR otherwise the model disappears! -> The mesh was well generated (looks like the tutorial)

I don't know why it does not work.
The file is too large to attach.
