*SetSolverVariable() - single solver variable with user subroutine

Sets the properties of a solver variable with a user subroutine.

Syntax

*SetSolverVariable(sv_name, USER, `solver_expression`) 
*Set(sv_name.use_local_dll, TRUE|FALSE) 
*Set(sv_name.local_dll, "string")

Arguments

sv_name: The variable name of the solver variable.; Data type: varname
USER: Indicates that a user subroutine is used to compute solver variable properties.
solver_expression: A solver expression enclosed in back quotes to specify arguments for the user subroutine.; Data type: string
sv_name.use_local_dll: Specifies if a user subroutine DLL is specific to the instance of one solver variable entity.; Data type: boolean
sv_name.local_dll: The path and filename for the user subroutine DLL to be used with an instance of the user defined solver variable.; Data type: string

Example

*SolverVariable(sv_solvervariable, "Solver Variable" )
*SetSolverVariable(sv_solvervariable, 
 `7*DZ(marker1.id, marker2.id, marker2.id)`)

Context

*BeginMdl()

*DefineAnalysis()

*DefineSystem()

Comments

The solver variable is generally used to define a variable that is an algebraic function of solver parameters. This solver variable can then be referenced by other solver variables or passed into a user subroutine.
