Description
Creates a dvprel that relates a design variable to model properties.
Inputs
- name
- Name of the dvprel.
- entities
- The entity type which the dvprel is attached. Valid values are components, properties and elements.
- id
- The property ID.
- property
- Property type identifier. The possible values are:
- 1 - pshell
- 5 - pbar
- 6 - pbeam
- 7 - pelas
- 8 - prod
- 11 - pbush
- 14 - conm2
- field position
- Field position in property card. For more information about this field, refer to the DVPREL1 and DVPREL2 cards in the OptiStruct manual.
- ndesvars
- Number of design variables.
- functionid
- ID of the DEQATN, if a DVPREL2 is to be created (=0, if DVPREL1 needs to be created).
- c0
- Constant in relationship equation.
- pmax
- Maximum value allowed for the property (Nastran only).
- pmin
- Minimum value allowed for the property (Nastran only).
- ntableentries
- Number of table entries (=0 for DVPREL1 card).
- int_array
- Unused. Always set to 1.
- nintegers
- Total size of the integer array. See comments below.
- double_array
- Unused. Always set to 1.
- ndoubles
- Size of the real array.
Example
*createarray(2) 1 2
*createdoublearray(2) 2.1 3.5
*dvprelcreate("dvp1",components,1,1,4,2,0,1.7,0,0,0,1,2,1,2)A *createarray() and *createdoublearray() are required to define the IDs and coefficients. While creating a DVPREL2 card, the first ndesvars items in the *createarray() command are the IDs of the design variables and the next ntableentries items are the IDs of the tableentries.
