  What should be the major consideration for checking mesh quality for 2D meshing among jacobian ratio, element quality, aspect ratio, skewness and so on options.
  
  Also what is the difference between Jacobian (MAPDL), Jacobian (corner nodes) and Jacobian ( Gauss points) also how to descide which one to use?

  Hello,
  
  I'd strongly recommend that you go through the following information on the Meshing Users Guide. The definition of what these quality metric mean and an understanding of how to read these values can be obtained through this.

  - Yes actually I know the value range for all of this terms but I am not getting how to descide the priority order for the same and the difference between Jacobian (MAPDL), Jacobian (corner nodes) and Jacobian ( Gauss points) .
  - Can you help me with these points?
