The purpose of the mesh generator is to decompose the flow domain into control volumes. Precisely where the nodes are relative to the vertices depends on whether the solver uses, for example, cell-centred or cell-vertex storage. Further complexity is introduced if a staggered velocity grid is employed.
Why do we mesh slab?
to provide lateral support(bracing) to structural elements which are not designed to resist lateral loads, to resist out-of-plane loads. For example, loads on the slab, uplift pressure due to wind action, etc.
Why is mesh quality important?
Importance of an Accurate and High-Quality Mesh A low-quality mesh will not only result in inaccurate simulation results but might even cause the solver to produce an error due to instability. Such instability is typically caused by poor-quality or illegal cells. This is something you want to avoid as much as possible.
