Models enable rapid insight into complex problems.
To an engineer the usefulness of a model is dependent on how much time and effort is required to generate a solution.
FFM has relied on improvements in computer technology to increase its usability and viability.
While great advances in computer technology have occurred and continue to occur, FFMs insatiable appetite for computational power is unlikely to be meet simply by advances in computer technology.
Improvements in the solution techniques at the core of FFM are also necessary.
This becomes more critical as capabilities of FFM increase to include, solid fuel combustion, sprinklers, structural steel, etc.
Consider two advances - Group Solvers and Dynamic Control.
