Post Inlet profile SU2 Fluid mixture

Hi,

I'm currently trying to specify a velocity profile for one of my inlets for a fluid mixture model, which is why I've selected the following options, after running it without specifying inlet profile:

RESTART_SOL= YES
SPECIFIED_INLET_PROFILE= YES
INLET_FILENAME= inlet.dat

I believe SU2 should create an example inlet file when no such file is present in the directory, but is doesn't create such an example file and it results in an error after "Reading inlet profile from file: inlet.dat".

It runs perfectly fine without specifiying an inlet profile, but for some reason it does not create the example inlet file after changing the options.

Does anyone know how to fix these issues?

Thanks in advance!

There seems to be an error when you do this in parallel, if you just run SU2_CFD without mpirun I get a restart file.

Thanks for your reply!

Does this only hold for fluid mixture? Because I does generate an example inlet file when running laminar step tutorial in parallel.

I would like to try running it in series, but my SU2 doesn't work in series, so I always use parallel. Probably, I need to fix that first.
When I'm running a simulation in series it will always directly result in the error "An error occurred in MPI_Win_create", which I think is quite strange for a series simulation. But because of that, I've always used parallel simulations.

There's an error with writing an initial profile when using mpi + multiple inlets:

SU2 should work in serial if you just leave out the mpirun command. We can discuss tomorrow.

The problem is fixed in develop and will be in the next release.
