To parallel or not ...

Developer .... .

I have been thinking about this issue and I need some opinions about it.

The issue is this, lets say that i have a unstructured grid based segregated solver. This solver solves for turbulence and heat transfer problems.

The issue to decide is this, this solver is single processor solver and i need to make it parallel version of it. But at the same time I could spend my time adding more interesting features to it. For example lets say chimera type of mesh support or immersed boundary type of support to it.

I can spend my time doing one of these tasks and i could not decide where to put my efforts.

So the question is what do you guys think is parallel solver is too much needed for people who use cfd or they would rather have a solver that provide something that other solvers do not provide.

For example Fluent CFX, starCCM , openFOAM etc do not provide immersed boundary type of solver. So i think it would be great to have.

Any input would be helpful.
