- functionCoupled function to evaluate with values from v
C++ Type:FunctionName
Controllable:No
Description:Coupled function to evaluate with values from v
- variableThe variable this initial condition is supposed to provide values for.
C++ Type:VariableName
Controllable:No
Description:The variable this initial condition is supposed to provide values for.
CoupledValueFunctionIC
Initialize the variable from a lookup function
CoupledValueFunctionIC initializes the value of a variable with the value of a coupled MOOSE Function which is evaluated with a set of up to four coupled variable values v as its input parameters. The coupled variable values are substituted for the x,y,z, and t function variables in that order.
One example application is the use of a PiecewiseMultilinear function with a data file containing a pretabulation of dependent variable values as a function of up to four primary variable values.
This capability can be used when internal degrees of freedom, such as phase concentrations in a KKS model, need to be initialized to a good initial guess to improve the convergence of the first timestep. In the KKS case, and physical IC will be applied to the primary global alloy concentration variables, and the phase concentrations will be initialized from pretabulated data containing good approximations of the phase concentrations for each primary global alloy concentration.
