It is generally advised to keep the minimum orthogonality greater than 0.15 and maximum skewness lower than 0.95. Having bad cells or elements can lead to incorrect simulation results. However, these are general guide rules and depend on the physics solved or where the cells are located. The following tables can help you gauge the quality of your mesh.
