Some errors occurred in my work. Somebody can help me?
 

I am a new guy who just begin to use openfoam. I want to compute a supersonic external flow field. But the system show some message like this:

/------------------------------------------------------------------------

Create mesh for time = 0

and this:

I must made some mistake. Thanks to the person who can help me first.
PS: I am a chinese and my english is poor.

Try 'fixedValue' in place of 'patch' for the far field pressure.
Just my 2 cents.

I do as what you said. But another error occured:

This does not necessarily mean you have run out of virtual memory.
It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library

Can you tell me what this mean? Thanks!

Are you using bockMesh to create the mesh?
The patch names in the mesh and the boundary conditions are inconsistent. If you have names the patches as say patch1, patch2... etc in the mesh, you need to use the same names in the boundary conditions for T, p, etc.

I don't use blockMesh. I made Mesh by Gambit and turn it into openfoam.

this is the boundary file:

how shall I do? It confused me.:(

The memory of my computer is not enough?
