Grid Tools: gridmerge
The gridmerge utility provides a tool to merge two or more volume grids together into a single composited grid. gridmerge resolves the connectivity issues between the constituent grids, such that the final output grid is a valid unstructured mesh.
| -ngrid [#] | Specifies the number of input grids to be merged. Upon execution, the user will be prompted for the grid names to be merged. |
| -ogrid [file_name] | Specifies the output grid file name |
| -abs_tol | Use absolute tolerancing to find matching nodes between grids instead of local tolerancing. This method is much faster but less reliable. [Default] |
| -rel_tol | Use local or relative tolerancing instead of absolute tolerancing to find matching nodes between grids. |
| -tolerance [#] | Specifies the maximum distance between two points such that they are considered as matching between constituent grids. For relative tolerancing, the tolerance is specified as a percent edge length (i.e. 1% is 0.01). The default value is 1.0e-8. |
| -cat | Do not attempt to merge grid points; instead, simply concatenate the grids together. |
| -renum_tag | Renumber the input surface tags such that each surface ID is guaranteed to be unique. The default behavior is to retain the surface ID's of the constituent grids in the final merged grid. |
| -surfid [#] | Merge only the surfaces with the specified surface id. Note: The specified surface id must be present in all of the grids. |
| -nlist [#] | Specifies the number of number of surrounding neighbors when building the node surrounding node list. The default value is 600. |
| -ignorevtags | Ignore existing volume tags and assign new ones. |
| -dumpvtags | Writes the volume tags to an ASCII file. |
| -debug | Prints extra debugging information. |
| -printrejects | Prints extra information for candidate nodes that were not merged. |
| -flow | Merge/concatenate solution files in addition to grid files. |
| -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.
