Projection-Method with grid generated via Thompson algorithm (stretching function)
I'm trying to implement the projection method on a flow past a cylinder problem.
I have generated a grid for the cylinder via Thompson algorithm of the Poisson equations. Therefore the grid is (very) stretched and curvilinear.
When I descretize the NS equations, what is the appropriate stretching function I should use?
For example, for
what is the appropriate expression for ?
