18/35. Summary of experiences withFVM applied to solid-stress problemsLubbock,TexasOct 18 2013Applications of CFDMany comparisons with both analytical and finite-elementsolutions have been made.They confirm that FVM for stress-in-solids problems is practicable,accurate and economical; it is at least as good as FEM.This is a fertile field for research, still almost explored.SIMPLE works well for both fluid flow and solid stress; but surelybetter SSFT-specific algorithms can be found.Other questions remaining to be answered concern:relative advantages of staggered and collocated structured grids;and of (various kinds of) unstructured grids.Extensions are also required to time-dependent phenomena:• to large (enough to influence the flow) displacements; and• to non-linear and plastic deformations.
