[Maanieh.h]

Hello,

I want to introduce the dynamic mesh option to a scalar transport solver "ScalarTransportFoam".. There is no diffusion term to be solved in the equation, only pure convection and transient term. I don't know what include files should i put in the solver and in the create fields file . Please take a view on what I have in my files and I appreciate any comments.

The MyMovingScalarTransportFoam.C is below
