Dear Foamers

I am a beginner OF programmer trying to compile a simple modification to the driftFluxFoam velocity correction function Udm that looks like:



where f(x) is a combination of variables and g is gravitational acceleration.

My issue is getting the function to read g, which is a file in the transportProperties dictionary. When compiling I get an error messages like ‘g was not declared in this scope’.
I have tried many things like:
1. including the “readGravitationalAcceleration.H” file within some of the related files
2. adding a dimensionedVector term called ‘grav’ to the transportProperties dictionary itself then calling it along with the other velocity function variables
3. trying to define const uniformDimensionedVectorField in the modified file
4. looking at other default solvers and their functions for similar calculations

I feel like this is something straightforward and it's just lack of experience getting in the way but I've been at it for days now and any help would be much appreciated!!

Many Thanks!
