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.

In Examine, the function computed for a block is now set to None and the show status for cells in all ranges has been toggled off each time grridgen block is brought into Examine.

Please be aware that importing Gridgen restart. SPR An bug that kept blocks resulting from a prism extraction from being numbered properly within the execution of a glyph script was resolved. A new utility script is available DbImportPoints. SPR Fixed an issue that would cause Gridgen to vridgen when selecting a database group for copying using Pick: For example, you may want to only pick surface entities, or only circular arcs.

SPR Fixed a bug which was keeping the split connector cursor location from being updated in the Display window when manipulated from the keyboard. Logic has been added to Gridgen to prevent this from occurring. SPR An issue was found in which modifying the original database constrained connector in a periodic pair removed its grridgen associativity.

SPR The smoothed domain was not being retained after smoothing a domain that had an edge with an orthogonality boundary condition. You may select a block, for example, that was created by extrusion and Re-Extrude will allow you to continue the extrusion process with all the functionality of Extrude in the Create menu: SPR Fixed a problem in which Pick: SPR Logic was added to correct a bug that was causing Gridgen to split an STL file into many entities on import when no default split angle was specified.

Logic has been modified to handle these domains. A preference has been added to allow users to choose whether it is maintained or not. This is useful griden splitting the curve using a point generated by a closest approach intersection see below.

SPR Resolved a bug which was causing poor results for a domain that was being copied then rotated.

The following is a listing of technical issues resolved in V SPR Corrected the decimation of cells near a symmetry plane in an unstructured anisotropic tetrahedral block. Logic has been added to grdigen this problem. SPR Gridgen was not checking appended grids for identical block names for cases in which the appended and original blocks did not touch. SPR Corrected a problem causing gridyen growth of anisotropic cells in concave regions. SPR When journaling block face creation that included unstructured domains, erasing a domain that had been selected caused mnual when the journaled script was executed.

Improvements have been made in the manner in which Gridgen creates unstructured domains on highly curved shell entities. SPR Gridgen was found to crash when trying to re-extrude a copy of an extruded gridgne block whose computational coordinates were aligned differently from the original. Export routines have been modified to fix this problem. SPR Fixed a bug in which both sides of an unstructured baffle were not meshed even though the Mesh Both Sides option was enabled.

Models will allow users to form collections of adjoining quilts and trimmed surfaces. Glyph commands have since been changed and one added to correct this issue. Users can now extend the functionality of Glyph scripting by linking in their own C routines compiled as dynamic libraries. SPR Resolved a bug that caused the redimensioning of a connector to be journaled incorrectly from Gridgen.

SPR Resolved bug in which a database model was displayed in the lower right corner of the Display window and could not be centered. March Resolved a bug in which Gridgen was unable to export the analysis boundary condition file for Cobalt. SPR Fixed an issue that prevented the volume condition information of an anisotropic block from being propagated into its component tetrahedral and prism blocks during prism extraction.

SPR Corrected an issue which caused many errors to be generated when saving large unstructured blocks. SPR Fixed an issue that caused all boundary conditions to be removed from a block when an additional face was added.

SPR Hyperbolic extrusion from an edge on a particular grid using a geometric growth rate of 1 was causing a core dump floating point exception in Gridgen. Then when it is time to work on the wing mesh you can use the layer manager to make only that layer visible. SPR The grigen for linear projection was not getting updated in the Blackboard during model manipulations.

The following is a list of technical issues resolved in V Tolerances that were causing this problem have been adjusted. Gridgen bit for Linux workstations is now available. SPR An issue was found in which all database entities selected for rotation did grixgen rotate at the specified angle. Gridgen is now supported on SGI Prism workstations.

Gridgen now allows the use of mixed extrusion types using From Cons domain extrusion gridgne From Doms Block extrusion. These additional points provide greater refinement and transition for regions where anisotropic cell advancement has to stop locally. The logic involved in this process has been modified to prevent this from occurring.

SPR Resolved a bug in which the connector information was not displayed in the Redimension Grids Blackboard when a connector was highlighted. Manuual The following is a list of new features included in V The Unigraphics native file reader is an optional product. SPR A bug grixgen fixed which caused Gridgen to exit when journaling the extrusion of a domain from an edge. Logic has been added to handle this scenario so that the data will import correctly.
