I modified the blockMesh and boundary dictionary in the forward step case in sonicFoam to simulate a supersonic jet. The blockMesh executed Ok but when I tried to compile I get the following error message.

--> FOAM FATAL IO ERROR : size 1250 is not equal to the given value of 5250

Shou,

This is an error in your initial pressure field Jet/0/p. You have changed the meshing and now have more points in your domain. I am assuming that you have a nonuniform initial pressure field. It appears as though you have only specified the pressure on 1250 of the required 5250 points. Alter you initial pressure field and it should run.

Hope this helps,

Shaun
