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
