I never calculate mesh quality as long as the code converges to the desired solution, i.e satisfy the tolerance, for all mesh levels. Check if your solution changes when you refine your mesh. If no spesic changes then your are just fine!

As per your approach first we have to run the solution in CFD solver and check the conversion. But if mesh is large i don't think we have enough time to just run the solution with unchecked mesh to see that mesh quality is good enough or not. We have to be as sure as possible that mesh is good enough to cause minimum problems in solution conversion before running the CFD solver.
i hope i made myself clear.

Ask your CFD support for the criteria of mesh quality. If you use CFX and ICEM for example they can give you all necessary criteria you need.

Some packages have built in features to help you evaluate/fix your mesh.
