Error with sonicFoam simulation - 'keyword ffminx is undefined'
[EDIT] I accidentally mis-titled this thread... Is it possible for a mod to change the title to "Error with sonicFoam simulation - 'keyword ffminx is undefined' " ?
Hi guys, and a happy new year.
I'm trying to model the flow over an aircraft wing with sonicFlow.
I've generated a tentative mesh of my wing (I'll need to refine it further) and I'm now trying to set up my initial conditions by copying the required files from the sonicFoam/ras/nacaAirfoil tutorial.
When I run sonicFoam I'm getting the following error:
Thanks in advance
OK, I've noticed that 'ffminx' is the name given to one of the patches generated by HelyxOS.
Possibly the way I'm meshing is causing me problems...
I initially meshed with HelyxOS but my wing's trailing edge was badly meshed due to the sharp edge. So I applied the SurfaceFeatureExtract tool by executing:
However when I execute sonicFoam, I get the error posted in the original post. Possibly this is bad practise which is causing the described error?
Thanks again, and sorry for the double post.
ffminx is one of the patches HELYX generates (the plane corresponding to minimum x). The error relates to the 0/P file which does not have a definition for ffminx. It sounds like switching approaches half way through has left some loose ends.
I would start by checking the boundary conditions in the U and P files have entries corresponding to the blockMesh and snappyHexMesh dictionaries.
A note on sequence too. I have always got very confused if I mess with the sequence because old files get left behind. So once you are happy with the boundary conditions, I would copy the dictionaries to a new case and then run the mesh generation process from scratch.
Hope this helps
