Creating custom implicit solvers

You can write an implicit static solver as a DLL. To do so, activate the User Defined parameter in the dialog box for the Simulate > Optimization Properties command. A user-written solver is then used. Note the following about a user-written solver:

•      It must be named VSOLVER.DLL

•      It must reside in your current directory when you initiate implicit static solving

•      It must contain the exported function userSolver() that is called at each time step
