Suyf is on a distinguished road
I am an OpenFoam newbie using Ubuntu Linux 14.04 and OpenFoam 2.3.1. I am trying to modify code from someone else, but keep getting the following error:

Cannot find file "points" in directory "polyMesh" in times 0 down to constant.
There is discussion of the error in forums, but I don't think I can use it to solve my problem (or maybe I don't understand it). A lot of it is related to the OpenFOAM tutorials and advice seems specific to the tutorials, which I can run no problem.

I think the problem is likely to be related to the fact that I'm running in serial, but the code was made to run in parallel. The reason I think this is that I have two "processor" files in my run directory. Inside each processor file is a "points" file (under constant/polyMesh). In the run directory under 0/polyMesh, there are no files. Here is what I have tried so far:

In the run directory under system, I tried modifying "decomposeParDict" by changing "numberOfSubdomains 2" to "numberOfSubdomains 1" and also deleting the processor files. I got an error:

Cannot open mesh description file
This made sense because there was no blockMeshDict in that location. Next, I copied blockMeshDict there from the "system" directory. I then got an error that file p_rgh was missing from run directory/0/p_rgh. I found that file in each processor directory, so picked one and moved it to /0. Now I'm getting:

Cannot find patchField entry for XXX
file: /0/p_rgh.boundaryField
I think this is related to boundary conditions, but I don't know what to do next. I guess my question is, am I on the right track that my problem is likely to be related to parallel/serial? If I am, is there a simple recipe for changing from parallel to serial?
