Solid Mesh

The solid mesh is the collection of points on the object’s surface \(X_{\alpha}\). It is recomendable that its resolution coincide with the fluid grid refinement (\(n\)). Ideally, the solid points should be uniformly distributed. However, This is difficult to assure in practice, so, a low degree of non-uniformity is acceptable. The figure below illustrates two different meshs of the same geometry. Despite left mesh having a higher resolution, the right one is the more adequate for a IBM simulation, because the points are more evenly spaced.
