Hi everyone, What's the point
 
Hi everyone,
What's the point of defining mvConvection object? why not simply using fvm:div(phi, Yi) and fvm:div(phi, h)?
Thanks,
Mahdi

Hello mehdi
Did you get any response to this question?

It seems that the reason should be
All the div(phi, Yi) and div(phi, h) have a similar discretization form, except for the tracked variable. With mvConvection object, you can use a single surface interpolator (multivariateSurfaceInterpolationScheme) for all the div(phi, Yi) which will save a lot of efforts for setting the discretization scheme. Such a treatment can also speed up calculation relative to the form of fvm:div(phi, Yi).

Hope this helps.

Regards, Junwei
