Boundary layer mesh
These preferences control the boundary layer mesh properties.

  • Stretching function: this variable set the stretching function which controls the height of each layer of boundary layer mesh. Options are the next ones, where 'h_i' is the height at level 'i' and 'r' is the grow factor:

·Function 1 (Geometric): This function is the geometric progression, and its expression is: h_i = h_0*(r^0+r^1+r^2+···+r^(i-1)
·Function 2 (Exponential): This function the exponential progression, and its expression is: h_i = exp(r*i + ln(h_0)).
·Function 3: This function is represented by: h_i = h_0 * (1 + i*(1+r*(1+r)*i))) . This function typically grows faster than the Geometric one.

  • Grow Factor: This variable controls whether the stretching function grows slower (smaller values) or faster (bigger values). When Function 1 is used, grow factor must be greater than 1.0, and when Function 2 or 3 are used, grow factor must be a positive number.
  • The red line below these options shows schematically the difference of heigt of the different layers of boundary layer mesh.
  • Boundary layer mesh in separated Layer: if this preference is set, the mesh elements which own to a boundary layer mesh will own to separated layers. The name of these layers will be the same as the Layer name of the geometrical entity where elements are, but with the prefix 'BLM_'.

Cartesian mesher
These parameters control the properties the Cartesian grid meshes:

  • mesher: algorithm selection:
    • Scan convert: voxelize in 3D with a scan convertion algorithm
    • Zmesher: developed by UGR
  • Shape: From geometry or from mesh: shape obtained from the render mesh of the geometry (faster) or from an standard mesh

  • grid spacing: Uniform spacing for the whole model, or variable spacing.
  • Minimum size: minimum grid spacing allowed.
  • Size ratio: ratio between sizes of neighbor cells on each x,y,z direction.

Utilities Menu>Preferences>Meshing>Sphere circle
This set of preferences controls the parameters for generating circles or spheres meshes.
Depending on the installed plugins it is possible to have more than one sphere mesher, then a 'Selected mesher' option will appear in order to set the current sphere mesher to use (for volumes/surfaces with element type assigned sphere/circle).

Preferences Window: Meshing->Sphere / circle->Selected mesher
Utilities Menu>Preferences>Meshing>Sphere circle>RBall
Rball
Rball is a sphere or circle mesher included internally in GiD.
It has several algorithms in order to try to pack spheres with tangency.
Spheres are tried to be packed without cross the volume boundary.
The different options to choose are:

Preferences Window: Meshing->Sphere / circle->Rball

Algorithm
·Optimization radius: iterative, optimizes distances and positions for minimum porosity.
(ref:Carlos Labra, Eugenio Oñate. High-density sphere packing for discrete element method simulations, Communications in Numerical Methods in Engineering 2009)
·Porosity predefined : iterative with fixed radius .Experimental.
·Explicit: iterative, radius defined with porosity and optimizes positions. (Experimental)
·Radius expansion : iterative, corrects positions and increases radius.
·Optimization radius fast: it's 'Optimization radius' with less precision. (Experimental)
·Position correction and inflate
·Optimization radius corrected

  • Delta radius factor: Randomness of initial radius. Minimum radius = (1-DeltaRadius)*UserRadius; Maximum radius = (1+DeltaRadius)*UserRadius.
  • Min. radius factor: Minimum radius Factor. Minimum radius = MinRadius*UserRadius(size of element/2).
  • Max. radius factor: Maximum radius Factor. Maximum radius = MaxRadius*UserRadius(size of element/2).


Options

  • Max. iterations: Maximum number of iterations for the choosed algorithm.

  • Preprocess with porosity: Initial generation of spheres with porosity.

·Porosity: Value of porosity for preprocess.
·Postprocess: correction of final positions. (Experimental)
·Overlaps: Checked permits overlaping between spheres. If not checked corrects radius of the sphere.
Note: Delta postition and Delta radius: define randomness of generations: if both of them equals 0, the generation will be structured.
Note: Maximum values recomended for Delta position and Delta radius:
2D: delta position: 0.6; delta radius:0.6
3D: delta position: 0.4; delta radius:0.4

Sphere and circle main options

  • Boundary tolerance factor: This parameter is a relative factor of the maximum element size, it is used to set the maximum distance to find a particle considered as belonging to the boundary. Value 1.0 (default) means that it will be considered as boundary all particles with distance to boundary less or equal to the maximum diameter defined.

Utilities Menu>Preferences>Meshing>Other

Preferences Window: Meshing->Other

Mesh / NoMesh

  • Mesh until End: If this preference is set, the mesh generator will continue until it has completed the meshing process, even if there are surfaces or volumes that cannot be meshed.
  • No Mesh Frozen layers: If this preference is set, entities belonging to a frozen layer will not be meshed.
  • Mesh always by default: this option Changes the default Mesh/NoMesh meshing criteria (Mesh NoMesh). Entities will always be meshed even if they have higher entities. Example: If surfaces are checked when meshing a volume, volume elements and surface elements will be obtained.


Others

  • Smoothing: You can choose the level of smoothing required to enhance the mesh after the generation. It is applicable to unstructured meshes. Options are:

·Normal: only the standard laplacian-like smoothing is performed.
·HighAngle: an additional smoothing trying to improve the angle of the elements is performed.
·HighGeom: an additional smoothing with a chordal error criteria in order to adapt the mesh in high curvature areas of the model is performed.

  • Avoid elements with all its nodes in boundary: if this option is set, there won't be any element in the mesh which has all its nodes in the boundary of the geometrical entity. This is only applicable for unstructured meshes.
  • Allow quadrilateral dominant meshes: If this preference is set, unstructured quadrilateral mesh generator is allowed to use some triangles in the quadrilateral mesh in order to improve elements quality. This option only affect to the mesh of surfaces not belonging to any volume.

Utilities Menu>Preferences>Import and Export
The fourth group of preferences are geometry exchange (import and export) options.

Preferences Window: Import and Export
Import

  • Automatic Collapse After Import: If this option is set then after reading one external format file (IGES, DXF, etc.) one global collapse is made. If it is not set, all surfaces and lines will be independent of each other.
  • Automatic Import tolerance: When importing a file or collapsing entities, any points closer together than this distance are considered to be the same (see IGES). Lines and surfaces can also be collapsed.
  • Collapse:

·Ignoring Layers: Entities are also collapsed if they belong to different layers.
·Each layer separately: Entities in different layers are not collapsed. (Entities belonging to frozen layers are never considered.)

  • IGES: Curve on surface from 3D: If this option is set, IGES curves on surface entities are created from the direct 3D space definition (recommended); if the option is not set, IGES curves are created from the surface space parameter definition.
  • IGES: Create all in 'layer to use': If this option is set the IGES entities are created in the current layer to use, instead of using the file layers.



Export

  • IGES: B-Rep output style: If this option is set, exported IGES volumes are written with Boundary Representation Solid Model style; otherwise its surfaces are written as separated trimmed surfaces without topological information.

Some CADs are not able to read the IGES B-Rep style and then can be interesting to use the alternative style.
Utilities Menu>Preferences>Fonts
The user can select the fonts for the diferent text objects with the Fonts panel in the preferences window.
In postprocess a new fonts management system has been implemented. Now GiD uses directly True Type Fonts (R) to draw text inside the postprocess graphical windows.
This allows to draw the characters with smoothed edges.

Preferences Window: Font
Graphical postprocess fonts
Used to draw text in the graphical windows (OpenGL):

  • Legend / Comments font: used to draw the legend and comments.
  • Labels font: used to draw the nodal, elemental, results o minimum and maximum labels.
  • Graphs font: used to draw the labels on graphs.
  • Asian font: used to draw the text when special charactes are detected, which requires special utf-8 codes.
  • Quick bitmap font: used to draw fonts when needed.
  • Render mode: allows to enable or disable the smooth edge drawing.


The True Type Fonts used in GiD are the free ones provided with GiD and the ones provided by the system: %WINDIR%\fonts in Microsoft Windows, and several directories in Linux (remember to install the true type fonts, or free type fonts from your favorite package administrator).
Utilities Menu>Preferences>Grid
The seventh group of preferences contains grid options (see Grid).
This 'working grid' is an auxiliary grid on the xy plane that allows the user to select the coordinates of points in its grid nodes, setting the 'Activate snap' option.
Also this grid is a visual aid to know the dimensions of the model.
Note: If the model has defined with cartesian mesh type, then this 'cartesian grid' is drawn instead the 'working grid'.
The cartesian grid define the tick location on the three axes: x y z, not only the x y as the 'working grid', and these location could be non uniform (not equi-spaced spans)

Preferences Window: Grid
General options

  • Show axis: If this option is set, 2D axes are shown in the grid (X and Y).
