Minimum Length nozzle

Hi dear OF users
I am new in OpenFoam, and I am doing a project which design the nozzle by using the method of characteristic, first i get the contour and use blockMesh to creat the Mesh, and now here is my problem, which solver should i choose?
I assume that should be a isentropic flow, and set the boundary as attach, and using both sonicFoam/forwardStep and rhoCentralFoam/forwardStep , but both of them did not show the results i expect.
can anyone tell me which part i did wrong?
Thanks a lot for your help

I'm also new to OpenFOAM. I can't get my problem solved either
but concerning your problem, I have some remarks.
in "0/p" the "value" for totalpressure is missing, only p0 is given. further the "fieldInf" is only 1 Pa, I guess that's supposed to be closer to 1e5.
I'm no CFD specialist, but you build on a case with scaled physical properties, where 1m/s equals Ma=1, all this at 1K and 1Pa, so I'd put real world thermophysical properties, as well as real world Temps.
