(a) GROUP SOLVER
A novel new solution procedure known as the group solver has been developed for SMARTFIRE.
Computational domain split into a collection of groups.
Group is a collection of cells which has independent control parameters.
This allows the solution process to be controlled by directing computational effort where it is needed.
It is particularly useful in large domains such as tunnels or airport terminals.
Savings in computational time of over 30% have been demonstrated for relatively small problems.
