GRIDGEN MANUAL PDF

Pointwise supports exporting Gridgen grid files. A Gridgen restart .gg) file compatible with Gridgen Version 15 can be exported from Pointwise. © – Pointwise supports importing Gridgen database files. Any Gridgen restart .gg) file from Version 15 is supported for import into Pointwise. Note that 2D blocks are not supported by Pointwise and will not be imported.

SPR Resolved a problem in which applied interval shading for a database surface was not retained after the creation of a connector on the surface. March The following is a list of new features included in V The layer manager includes the ability to move entities from layer to layer, name layers, turn on and off the display of individual layers, create layer sets for easy recall, save layer data to Gridgen’s composite database file format, and read layer information from CAD files.

SPR A bug which caused the tetrahedral block to be deleted during prism extraction for an anisotropic tetrahedral block has been resolved. Glyph commands have since been changed and one added to correct this issue.

Improvements have been made to the performance of anisotropic triangles and tetrahedra marching out of concave regions. SPR Fixed a bug which was causing Gridgen to exit when importing a database composite file containing a model with 0 faces.

Gridgen – Pointwise

SPR Resolved a bug that caused Gridgen to crash when trying to import a restart file associated with a composite database file containing an isolated empty layer. SPR Fixed a bug which caused Gridgen to exit when importing a database composite file containing a corrupt trimmed surface.

June The following is a list of new features included thus far in V A new utility script is available ConSplitAtIsect. SPR An issue was fixed which caused poor gridgn unstructured domains to be created on quilts of high curvature.

Tolerances that were causing this problem have been adjusted. August The following is a list of technical grigen resolved in V SPR Resolved an issue which was causing Gridgen to crash when importing a particular restart file.

SPR The -extents flag was not documented for the gg:: SPR Domain projection onto a quilt was causing Gridgen to exit. SPR Fixed a bug in which the unstructured face normals were being calculated incorrectly for structured domains within the face.

SPR After receiving reports of problems using Gridgen in conjunction with an ATI Rage graphics card, a section was added to the Gridgen Hardware Requirements to document graphics cards with known Gridgen compatibility problems. The Auto toggle next griddgen the Coons button indicates whether you will create the Coons surface manually Auto toggled off by picking in sequence the curves around the perimeter, or automatically Auto toggled on by picking several entities and mabual Gridgen make as many surfaces as it can find from the selected data.

December The following is a listing of the new features that have maual added to V In order to more closely couple Gridgen with your analysis software, support for volume conditions i.

Gridgen only accepts angles between 0 and degrees for the split angle. SPR Setting the ConSplit angle to 45 degrees for shell entities was causing empty domains to be created. Logic has been changed to correct this problem.

SPR For grridgen databases, a trimmed surface could not be created from calculated intersection curves. Gridgen now features updated license management software. These scripts are provided for demonstration purposes and are not supported by Pointwise, Inc.

For example, you can create a group consisting of all the connectors on the symmetry plane or all the domains on the database. The Gridgen tetrahedral mesher has enhanced error reporting for unstructured volumes that are problematic to initialize.

SPR Fixed a bug which allowed non-visible grid entities to be pickable during domain and block assembly. By default, dimensions of the block i, j, k are set to Logic has now been added to account for this scenario and prevent this problem from recurring.

This has been fixed. SPR Corrected a problem with the Glyph command gg:: July SPR A bug was resolved which caused Gridgen to crash when deleting a control point that coincided with the end of a connector. The database Intersect command has been enhanced with the addition of Closest Approach intersections for curves.

These additional points provide greater refinement and transition for regions where anisotropic cell advancement has to stop locally.

mannual The Defaults menu now contains a preference which controls whether the Examine command automatically uses the diagnostic function chosen for the last block or blocks in Examine for any new blocks brought into Examine. The following is a list of technical issues resolved in V SPR Resolved an issue that was causing the boundary decay factor for unstructured domains to influence the number of anisotropic layers created.

SPR Resolved an error causing a crash when selecting gridgne for face assembly. Logic has been added to handle this scenario so that the data will import correctly. March The following is a manuual of new features included in V March New features included in V A new Glyph command has been added which allows users to momentarily pause a running script to pick database, connector, domain, block, or breakpoint entities.

So if you create a block, assign boundary conditions, but then delete the block, the boundary conditions are not lost.
