Description
Writes a design variable.
Inputs
- id
- The ID of the design variable.
- name
- The name of the design variable.
- config
- The configuration of the design variable. The possible values for configuration are
listed below:
Config Type of design variable 103 Gauge 108 Topology 115 Size/Shape 116 Topography - lowerbound
- Lower bound of the variable. Valid only for gauge, size and shape variables.
- initialvalue
- Initial value of the variable. Valid only for gauge, size and shape variables.
- upperbound
- Upper bound of the variable. Valid only for gauge, size and shape variables.
- delxy
- Move limit for the variable during optimization. Valid only for gauge, size and shape variables.
- property
- Currently unused.
- xorder
- xorder for harmonic perturbations of shape variables.
- yorder
- yorder for harmonic perturbations of shape variables.
- xtype
- xtype for harmonic perturbations of shape variables.
- ytype
- ytype for harmonic perturbations of shape variables.
- shapedesignvariable
- id of shape design variable referenced by a topography design variable.
- minimumwidth
- Minimum width of bead (topography design variables).
- basethickness
- Base thickness of elements in topology optimization.
- designthickness
- Total thickness of elements in topology optimization.
- designable
- Flag to indicate if a topology variable is designable. If the flag is zero, the variable is not designable, else it is designable.
- drawangle
- Draw angle in degrees (topography design variables).
- drawheight
- Maximum draw height of bead (topography design variables).
- bufferzone
- Flag to indicate if a buffer zone exists for a topography design variable. If the flag is zero, no buffer zone exists. A value of 1 indicates that a buffer zone exists.
- boundaryskip
- Boundary skip parameter for a topography design variable. The possible values for
boundaryskip and their definitions are listed below:
Boundaryskip Meaning 0 skip both load and spc 1 skip loads 2 skip spc’s 3 don’t skip - type
- Symmetry type of a topography design variable. A complete description of the possible values for type are described in the OptiStruct on-line help.
- anchorpoint
- Anchor node id for a topography design variable.
- firstgrid
- Node id defining the direction of the first vector of a topography design variable.
- secondgrid
- Node id defining the direction of the second vector of a topography design variable.
