Creating custom implicit solvers

You can write an implicit static solver as a DLL. The following limitations apply:

•      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

To use a custom implicit static solver, activate the User Defined parameter in the Simulate > Optimization Properties dialog.
