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.

If other dimensions are desired, they must be specified within the script interface. SPR Fixed a graphics issue in V Logic was added to rectify this situation. If you import a Gridgen. The restart file has been replaced to fix this problem.

Gridgen – Pointwise

SPR Corrected a problem causing rapid growth of anisotropic cells in concave regions. SPR A problem was encountered with a database trimmed surface containing a hole with two bounding curves. SPR Setting the ConSplit angle to 45 degrees for shell entities was causing empty domains to be created. The ability to extract prism cells from an anisotropic block at any time gridgeen been added to the block unstructured solver. 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 added to make unstructured triangulation more robust in Gridgen. SPR Resolved a problem preventing sufficient anisotropic tetrahedral recombination. This problem occurred for both normal copying and rotation as well as for a periodically copying it through rotation. SPR Resolved a bug which caused Gridgen to exit prematurely when executing a certain Glyph script.

SPR An issue that was keeping a pole domain that had been split from being rejoined has been fixed. The Catia V5 native file reader is an optional product. This provides users with the ability to: SPR An issue was fixed which caused poor quality unstructured anisotropic domains to be created on quilts of high curvature.

SPR Extracting prisms from an anisotropic block were causing the original boundary conditions set on the block to be moved fridgen different faces.

This new version contains improvements to the speed of the anisotropic tetrahedral mesher and the ability to mesh volumes with larger ranges of cell sizes. On Box could not be used in selecting domains to apply BCs. You use pick masks to limit the types of database entities that are pickable. SPR A bug was fixed in which the Layer Height settings were not being accurately applied to the edges of an anisotropic domain.

No matter what is visible in the Display window, pick masks ensure you will only pick what you want to pick. Gridgen can now run connected T-Rex blocks simultaneously manial the unstructured solver.

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.

SPR Resolved an issue that was causing the boundary decay factor for unstructured domains to influence the number of anisotropic layers created. The Glyph logic which vridgen this to happen has been modified.

Gridgen – Pointwise |

Grisgen There are currently no new technical issues resolved in V An extrusion boundary condition has been added that allows a hexahedral or prism block to be extruded while its boundary is constrained to a pre-existing connected structured domain in the grid. Gridgen now supports the export of FrontFlow analysis software files. SPR Resolved a problem which was preventing a journaled Glyph script from re-executing in 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. The two points the user hridgen define correspond to the computational minimum and maximums of the block. SPR Fixed an mqnual that would cause Gridgen to terminate when selecting a database group for copying using Pick: The following is a listing of technical issues resolved in Version
