For this walkthrough, I'm looking at another finite element analysis (FEA) software product. I recently described the background to Altair SimSolid and its technology in an article on meshless FEA methods (DE, January 2019, digitalengineering247.com/r/22097).
SimSolid uses the complete geometric domain to define the displacement response. There is no subdivision into traditional elements. The solver adapts by increasing the number of internal calculation points until convergence of the displacement boundary conditions is reached.
