Parameterised_boundary NUM=ival where ival is the data structure number |
Description |
Overview The Parameterised_boundary data structure may be used to define parameterized boundary conditions for associated geometry sets (or alternatively spatial grids if used). This allows a non-constant value to be prescribed on the boundary condition (e.g. a displacement on a boundary may be applied with a linear distribution or a quadratic function). The number of parameters required to define the boundary condition will depend on the distribution type (i.e. 1,2 or 3 for constant, linear and quadratic distributions respectively). When using the optimisation workflow for optimising boundary conditions (e.g. optimising boundary displacements to match a target stress state at various (well) locations on the domain) the data structure is left blank in the template datafile and the data will be automatically populated for every model generated.
