Description |
Overview Material grid data structure for each grid
Notes •One Material_grid data structure is defined for each material grid •A material grid can only be assigned to a single group •The Material_grid_set data structure may be used to assign material grids to multiple groups
Examples demonstrating the usage of Material_grid include: •adr_2d3n_004.dat •his_3d4n_001.dat •grd_2d3n_001.dat

 | Name Name of material grid |
Usage |
||||
|
||||
Description |
||||
Name of material grid
|
| Group Group number |
Usage |
||||
|
||||
Description |
||||
Group number to be assigned this material grid
|
| Grid_length_X Grid length in X direction |
Usage |
||||
|
||||
Description |
||||
Grid length in x direction. If Grid_length_x is not specified the grid will extend from the origin in the local X direction to cover the complete group.
|
| Grid_length_Y Grid length in Y direction |
Usage |
||||
|
||||
Description |
||||
Grid length in Y direction. If Grid_length_y is not specified the grid will extend from the origin in the local Y direction to cover the complete group.
|
| Division_size_X Grid division size in X direction |
Usage |
||||
|
||||
Description |
||||
Grid division size in X direction
|
| Division_size_Y Grid division size in Y direction |
Usage |
||||
|
||||
Description |
||||
Grid division size in Y direction
|
| Cell_stretch_tolerance Cell removal tolerance |
Usage |
||||
|
||||
Description |
||||
The cell removal tolerance allows highly distorted cells to be eliminated when the grid is displayed in the post-processor. The cell removal tolerance should be > 1.0 and is typically set to 4.0 (Corresponding to a distortion of ca. 400%).
|
| Rotation_2d Rotation of grid in 2-D |
Usage |
||||
|
||||
Description |
||||
Rotation of grid in 2-D in Degrees (default 0.0)
|
| Grid_origin Grid origin |
Usage |
|||||||||||||||
|
|||||||||||||||
Description |
|||||||||||||||
The grid origin defines the lower left hand corner of the grid. If not specified the grid will be defined with origin at the lower left hand side of the element group.
|

| Grid_vector_X Grid vector in X direction |
Usage |
|||||||||||||||
|
|||||||||||||||
Description |
|||||||||||||||
Grid vector defining X direction specified as a vector with dimension 3 in 3-D. The grid vector is only required if the local X direction of the material grid does not coincide with the global X direction.
|
|||||||||||||||
| Grid_vector_Y Grid vector in Y direction |
Usage |
|||||||||||||||
|
|||||||||||||||
Description |
|||||||||||||||
Grid vector defining Y direction specified as a vector with dimension 3 in 3-D. The grid vector is only required if the local Y direction of the material grid does not coincide with the global Y direction.
|
|||||||||||||||
| Stripe_spacing_X Stripe spacing in X direction |
Usage |
|||||||||||||||
|
|||||||||||||||
Description |
|||||||||||||||
Stripe spacing in X direction i.e. horizontal stripes. The data is specified as a pair of spacing values for each configuration required. For example if a single set of stripes are required with alternating colours then the data comprises: Stripe_spacing_x IDM =2 JDM =1 1 1
See the effect of the tripe spacing in x direction in the following plot:
Notes •Note that the values specified in stripe spacing must be integer numbers
|
|||||||||||||||
| Stripe_spacing_Y Stripe spacing in Y direction |
Usage |
|||||||||||||||
|
|||||||||||||||
Description |
|||||||||||||||
Stripe spacing in Y direction i.e. vertical stripes. The data is specified as a pair of spacing values for each configuration required For example if a single set of stripes are required with alternating colours then the data comprises: Stripe_spacing_y IDM =2 JDM =1 1 1
Notes •Note that the values specified in stripe spacing must be integer numbers •Vertical stripes not implemented at the moment

| Stripe_numbering_x Stripe numbering in X direction |
Usage |
|||||||||||||||
|
|||||||||||||||
Description |
|||||||||||||||
Optionally, a specific identification numbers may be assigned to the stripes to enable contouring with specific colours during post-processing. Stripe_numbering_x defines pairs of numbers for each stripe configuration in the in X direction (i.e. horizontal stripes)
|
|||||||||||||||
| Stripe_numbering_y Stripe numbering in Y direction |
Usage |
|||||||||||||||
|
|||||||||||||||
Description |
|||||||||||||||
Optionally, a specific identification numbers may be assigned to the stripes to enable contouring with specific colours during post-processing. Stripe_numbering_y defines pairs of numbers for each stripe configuration in the in Y direction (i.e. vertical stripes)
