Hi Jonathan,

I ended up using rhoCentralFoam; I never fixed the problem with rhoPimpleFoam.

Good luck,

The zeroGradient condition did not have a noticeable effect on the results - the Cp plot is still oscillatory. I changed all of the interpolation schemes to linear and the simulation did not...

I am not sure if it appears any sooner that the time in the file. I had set the transient sim to output data at that interval. I agree that it takes a long time - is there any way to accelerate this...

Hello Alberto,

I have tried to apply the case setups from the tutorial on my case, which is how I got as far as I did. I have attached my case, though I had to make a couple of changes for it to...

I gave up on rhoCentralFoam. SonicFoam looks promising, however when I change from Euler to backward differencing for the temporal terms, I get strange results (see pics). I think it is necessary to...

It looks like the boundary condition issue has been resolved by defining P at the outlet instead of the inlet and by using rhoCentralFoam. The p distribution is now free of anomalies. However, the Cp...

Hello Alberto,

Thanks for your suggestion. I ran a case with P defined at the inlet, and although I did not receive a floating point error in the time that I let the case run, the pressure...

Hello all,

I have run my 2D airfoil case successfully in pimpleFoam, but now that I try to migrate my case to rhoPimpleFoam, the boundary conditions misbehave and the simulation stops with a...
