Making changes to any of the .C files in the installation directory.

Hey foamers,
I'm new to openfoam and I had a very basic question .

I'm using openfoam 2.0.1

I'm trying to use rotatingvelocityBC.

I realised that I wanted to use the BC in a slightly different manner than how it was coded.

I made some changes to the .C file for this BC in the installation directory.(rotatingWallVelocityFvPatchVectorField. c)

Now ,I'm using the simplefoam solver.

When I ran the simulation again I got the same results.

I compiled the solver again and ran the simulation , however got the same result.

Do we have to compile the rotatingWallVelocityFvPatchVectorField.C file again for the changes to the reflect . If yes , how ?

Appreciate the help

Of course you have to compile your .C file, but you shouldn't modify them in the $FOAM_SRC directory. Make a copy of it and modify that one. You can find a lot of examples on the internet how to write your own solver and compile it.

You can find more details here:
