Data Structure: Support_data |
|
Description |
Prescribed fixity conditions for all fields |
Usage |
Support_data NUM=ival where ival is the data structure number |
Description |
Overview The Support_data structure defines the entities which have some or all of their freedoms prescribed. Prescribed fixity conditions may be specified for each field variable in the simulation; i.e. displacement, pore pressure and temperature. While the Support_data identifies that specific freedoms are prescribed, if the prescribed value is non-zero then the magnitude of the prescribed value must be defined using the Global_loads data structure. An example with typical definition of a support data structure for a 3D model with assignments performed via geometry sets is shown below.
Notes •One Support_data structure may be defined but it can be respecified for each stage. •If non-zero prescribed values are specified using the Global_loads data structure the relevant entities must also be defined as fixed (prescribed) using Support_data.
Examples demonstrating the usage of Support_data include: All examples
