Quality mesh

These were my results of mesh quality, what does target skewness mean?

Would my quality be poor? how could i fix it?

    Target is just a note to suggest a limit, and you've exceeded it. A max skew of 0.99999 means the cell is essentially flat (degenerate or may even have a negative volume) so must be fixed. At best the solver will fail fairly quickly, worst case the solver will take time to not converge and the result will be rubbish.

    Thank you very much, I will look for a tool that helps with the quality of the meshing, because I am working with very complex geometry.

    Right now I'm using the automatic method, you have any suggestions? I would appreciate your opinion.

    Automatic is fine, but you need to locate the bad cells and figure out what the problem is. It could be a rogue voxel in the scan conversion or a "thin" region that's not resolved.

    Automatic option is best option...but if u want to build a mesh in specific range of skewness, you can enter your limit there.. I don't to how much time it will take..
