SolidMesh Grid Tools: checkgrid

The checkgrid utility provides a tool to check the validity and angle quality of an input grid.
 

  • -igrid [file_name]
    		• Specifies the input grid file name
  • -ogrid [file_name]
    		• Specifies the output grid file name
  • -strength [#]
    		• Specifies the number and expense of the checks performed on the input grid.  Default value is 3.

    Strength < 1: Checks for

    • no invalid node numbers in element or boundary face maps
    • no negative element volumes

    Strength > = 1: In addition to previous strength levels, checks

    • grid connectivity for no flipped diagonals
    • element neighbor correctness
    • nodes belonging to no elements
    • edge connectivity correctness
    • nodes belonging to no edges
    • correct connectivity between surfaces and adjacent elements

  • -planar [#]
    		• Checks to ensure that the specified surface ID is planar
  • -angles
    		• Checks the dihedral angles for a volume grid or the or the face angles for a surface grid.
  • -min_angle [#]
    		• List elements that have angles less than the specified min_angle
  • -max_angle [#]
    		• List elements that have angles greater than the specified max_angle
  • -help
    		• Prints the help screen.
  • -version
    		• Prints the version information of the executable and the associated libraries
  • -build
    		• Prints the build number of the executable

    Options listed in red are mandatory.
