fijinx is on a distinguished road
Is there any way to implement runtime variables in openfoam? For example setting an inlet mass flow rate as a function of the average pressure over the boundary. I have looked through the documentation but did not see anything on this, perhaps I missed it.

Default groovyBC might be the answer

You might want to check out the utility groovyBc. For setting complicated boundary conditions or making them a function of another value (average outlet pressure), you might want to use this

there are also plenty of posts around here that deal with it.

Start here after the wiki:

hope this helps.
