Detailed Description

This is the base class for all Solvers. Solvers are the classes that perform the actual simulation for objects. The solver is passed a set of objects with mutual affector relationships.

Definition at line 25 of file SIM_Solver.h.

Member Enumeration Documentation

The possible return codes from a solve operation. These are kept in order of priority to make multi-solvers easier to write. Any result value from a subsolver that is greater than the previous highest subsolver result becmoes the new overall return value.

Enumerator
SIM_SOLVER_SUCCESS 
SIM_SOLVER_REPEAT 
SIM_SOLVER_SUBSTEP 
SIM_SOLVER_FAIL 
Examples:
SIM/SIM_SolverHair.h, SIM/SNOW_Solver.C, and SIM/SNOW_Solver.h.

This method solves for some objects. It performs whatever processing is necessary to take objects from their state at one time to another. The default implementation does nothing. The objects parameter holds all the objects that should be solved for this timestep. The newobjects parameter is a set of objects that were just created in this timestep, and so should in most cases not be solved on this timestep so that they maintain correct initial conditions.
