It identifies how the software appears to use an approximate integration scheme for some Element Table...
I recently worked on a project where a third-party had used LISA for a beam vibration problem. I undertook a software verification test (http://www.ramsay-maunder.co.uk/knowledge-base/simulation-governance/verification/beam-element-in-lisa/) to check that LISA was giving the correct solution...
In conventional FE packages there are generally lower and higher order elements. Lower order elements have nodes at the vertices whereas higher order elements have additional mid-side nodes. As the elements are iso-parametric, the nodes define not only the shape of the element but also the...
Hi 3JC,
I run a company that is developing limit analysis software that may be used for reinforced concrete and metallic plate structures. It includes the upper-bound yield line analysis method and a complementary lower-bound equilibrium method. Using both gives a bounded solution on the...
