Performing Contact Analysis can be one of the more complex non-linear finite element challenges in the daily life of a structural engineer. As we have many involvements with people performing these non-linear contact analysis for their finite element model, we notice that there are a lot of challenges which often are not addressed well because a lack of convergence and ever reducing time-steps. This is where we see a lot of trial and error approaches with the hope on a possible solution. Unfortunately many times the “hope” ends in a hugely stressful situation where you need to ask another company to do the analysis for you because you can’t seem to get it running properly.
