Issue created Dec 14, 2021 by Darrin Stephens@Darrin

extension of velocityDampingConstraint to allow damping on a selection of cells

Functionality to add/problem to solve

Extend velocityDampingConstraint fvOption to allow selection of cells to apply the damping to rather than the entire mesh.

Target audience

Anyone using the velocityDampingConstraint and only ned the damping in a specific region.

Proposal

velocityDampingConstraint is a cellSetOption and therefore can be easily extended to allow selection of cells rather than the entire mesh. This can be achieved by replacing line 67 in the addDamping function (velocityDampingConstraint.C) forAll(U, cellI) with for (const label cellI : cells_)

Funding

Functionality already exists, just needs to be enabled.
