Modifications to the finite element modeller program "REFINE" / by M.F. Palmeter - M.W. Chernuka.: D68-20/1-1990E-PDF

"Program REFINE was initially developed as part of an adaptive finite element modelling package for VAST where from estimates of discretization errors based on element residuals, the finite element model would be selectively refined (by element subdivision) until acceptable levels of accuracy (according to computed error estimates) where attained. However, increasingly the REFINE program finds application as a general modelling tool which complements the data generation capabilities of PVAST and HVAST. Under these circumstances, the PVAST and HVAST programs need only concentrate on achieving accurate geometric models, since subsequent refinement of the model to attain acceptable finite element accuracy can be achieved with REFINE. This is particularly useful when the initial model is defined in a pointwise fashion with a graphics table. In this context as well, selective model refinement would generally be employed but the experience of the modeller would dictate where the model refinements would be"--Abstract, page 6.
