UDF problem

Travis

I'm trying to write a UDF for a modified v2f turbulence model. I'm getting the following error:

Error: (path)\v2f.c: line 142: function returning double returns float.

That section of code reads like this:

DEFINE_UDS_FLUX(user_flux, f, t, eqn) {

switch (eqn) { case K: return F_FLUX(f,t); break;

case E: return F_FLUX(f,t); break;

case V2: return F_FLUX(f,t); break;

case F: return 0.0; <--- This is the line with the error break;

default: return 0.0; }

}

Any thoughts on why I'm getting that error?
