A reliable procedure for benchmarking of computer solutions in the fields of computational mechanics including computational fluid mechanics, heat transfer, and k-ε turbulence models is presented. The procedure consists of using assumed solutions to calculate the required source terms (which could be in the form of body forces for momentum equations) and use the resulting source terms as inputs to back calculate the displacements, velocities, temperature, etc. The procedure works especially well for nonlinear problems. Several examples are provided from fluid mechanics and heat transfer.
