From 8 to 9

What's new from version 8.0.x to 9.0.x 

PREPROCESSING
Visualize layer labels

Rhino import updated to version 4
DXF import: support of 3DSOLID entity (ACIS based)
Improvements in Parasolid import
CGNS mesh format import

 

Draw surface curvature : mean, gaussian, main directions. Get them with GiD_Info 

NURBS simplification operators: knot removal and degree reduction for curves and surfaces

Volume split (similar to surface split, to divide a volume from a group of dividing surfaces)
Surface render using triangle strips
Join surfaces function.
Sphere element new mesh quality filters: NumNeighbors and SpaceFilling
Transparent layers
Combobox in the toolbar to select the current layer to use
Mesh/nomesh criteria can be applied also to points
Draw meshing data related to boundary layer and Points forced to the mesh
Advance bar when reading GiD projects
JoinSurfaces JoinCoplanary, new function to join coplanar neighbor surfaces
GiD mesh ASCII reading: separate material in new layers

MESHING
Meshing volumes with sphere elements and 2D surfaces with circle elements.

Align nodes of structured and semi-structured meshes (variable AlignSemiStructuredNodes)

Apply background mesh sizes also when meshing lines
NetCDF format import (only mesh)
New mapping algorithm when meshing using Rsurf mesher
Creation of voxels from an VTK file (structured points dataset), GiD_VTK2OrthoHexa Tcl command

Creation of hexahedra from an VTK file (structured points dataset), GiD_VTK2Hexa Tcl command
Creation of iso-surface of triangles from an VTK file (structured points dataset), GiD_VTKSP2MarchingCubes Tcl command
Option to avoid elements with all its nodes in the boundary
Advance bar improvements: show number of generated entities

Global option to force a maximum relative chordal error of the mesh in Preferences->Meshing

New Rjump window to make easier the entities selection
Different interpolation scenario (2d or 3d) in surface structured meshing depending on the surface mesher selected (RFast or RSurf).
New quadrilateral mesher

Boundary regular transition meshing preference

Smoothing of triangles and quadrilaterals: new option LaplaceSmooth to only apply a Laplacian smooth, with angle tolerance and try to save the enclosed volume
Delaunay volume mesher (GiD_Set VolumeMesher 1)

Split tetrahedra option
Cartesian mesher

RenumberMethod = 2 to renumber nodes following the XYZ axes
Boundary layer meshing in 2D
Swap normals in groups of line elements to orientate them coherently.

POSTPROCESSING
Smooth iso-surfaces with results visualization and animation:

Free iso-surface with smooth render

Vorticity iso-surfaces with contour fill of velocity
Isolines created for surface meshes when the iso-surface option is selected.
Options added: Iso-surfaces can be seen although all the meshes are switched off, and isolines can be switched off.
Stream lines implemented for hexahedra, prisms, pyramids and quadrilaterals

Options added for stream lines: length, initial step, maximum number of points
Stream ribbons as stream lines with detail level=2, with rotational, and the detail level 'points' shows the calculated points from the stream:

Stream line options

Stream ribbons of the velocity field with contour fill of pressure
Supported hexahedra of 20 nodes in postprocess
Macro to create a vector result from an scalar result
Support for spheres (defined by a center node and a radius) and circles (defined by a center node, a radius and a normal) in Postprocess. Spheres can be cut and create in circles. If the normal for the circles are not given GiD assumes the normal ( 0.0, 0.0, 1.0):
