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
