Material_grid_set

Contents

Data Structure: Material_grid_set
Description	Material grid set data structure for each grid
Usage	Material_grid_set NUM=ival where ival is the data structure number

Description

Overview

The material grid set data structure permits the creation of material grids for several element groups using a single set of definition data

Notes

•A material grid can only be assigned to a single group, so material_grid_set creates one grid for each requested group

•Only one material_grid_set data structure may be specified

Examples

demonstrating the usage of Material_grid_set include:

•grd_2d3n_001.dat

Group_names List of group names

Usage

Group_names		IDM=ival
Character Names
where	ival	Number of material grid groups

Description

List of groups, defined by group name, to be assigned this material set.

Groups List of group numbers

Usage

Groups		IDM=ival
Integer Values
where	ival	Number of material grid groups

Description

List of groups, defined by group number, to be assigned this material set.

Deposition_flag Deposition flag (1-Create grids on newly sedimented material, 0-existing material only)

Usage

Deposition_flag

Integer Value

Description

The deposition flag defines whether material grids of this type should be created on newly sedimented layers. Valid settings are:

• 0 - Only create grids on existing groups specified via Groups or Group_names (Default).

• 1 - Create grids on newly sedimented material.

Grid_length_x Grid length in X direction

Usage

Grid_length_x

Real Value

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

Grid_length_y

Real Value

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

Division_size_x

Real Value

Description

Grid division size in X direction

Division_size_y Grid division size in Y direction

Usage

Division_size_y

Real Value

Description

Grid division size in Y direction

Cell_stretch_tolerance Cell removal tolerance

Usage

Cell_stretch_tolerance

Real Value

Description

The cell removal tolerance allows highly distorted cells to be eliminated when the grid is displayed in in the post-processor. The cell removal tolerance should be > 1.0 and is typically set to 4.0.

Rotation_2d Rotation of grid in 2-D

Usage

Rotation_2d

Real Value

Description

Rotation of grid in 2-D in Degrees (default 0.0)

Grid_origin Grid origin

Usage

Grid_origin		IDM=ival
Real Values
where	ival	Number of dimensions

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

Grid_vector_X		IDM=ival
Real Values
where	ival	Number of dimensions

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

Grid_vector_Y		IDM=ival
Real Values
where	ival	Number of dimensions

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

Stripe_spacing_X

IDM=ival

JDM=jval

Integer Values

where

ival

jval

Number of stripe values (always 2)

Number of stripe configurations in X

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 stripe spacing in x direction in the following plot:

Grid_001

Notes

•Note that the values specified in stripe spacing must be integer numbers

Stripe_spacing_Y Stripe spacing in Y direction

Usage

Stripe_spacing_Y

IDM=ival

JDM=jval

Integer Values

where

ival

jval

Number of stripe values (always 2)

Number of stripe configurations in Y

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 present

Stripe_numbering_X Stripe numbering in X direction

Usage

Stripe_numbering_X

IDM=ival

JDM=jval

Integer Values

where

ival

jval

Number of stripe values (always 2)

Number of stripe configurations in X

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

Stripe_numbering_Y

IDM=ival

JDM=jval

Integer Values

where

ival

jval

Number of stripe values (always 2)

Number of stripe configurations in Y

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)
