COMSOL Multiphysics® Software Performance Improvements COMSOL Multiphysics® version 5.3 provides significant performance improvements as compared to version 5.2a and earlier versions. These are most noticeable when working with models made up of a variety of several thousand domains, boundaries, edges, and points. The following table shows the most important of these performance improvements and the estimated speedup when handling larger models. Functionality Speedup* Selections of domains, boundaries, edges, and points 10x Virtual geometry operations (collapse faces) 10x Swept meshing 10x OpenGL® rendering 10x CAD import 5x COMSOL native geometry kernel 5x Load/save of MPH-files 2–10x *The actual speedup may be better or worse depending on the details of the model. Certain performance improvements were introduced in version 5.2a.
