Performance impact of complicated meshes

Asked by Colin Power

Hi, I am curious as to what kind of impact increasing the number of elements in a triangulated mesh can have on the simulation speed.

For quick testing I have an imported mesh that contains about 500 elements. Soon, I want to scale this up to at least 20000 elements so that I can have more triangles for post processing. If it has only a minor impact on performance I might want to use even more elements. I have also considered reducing the number of elements on the more "useless" sides of the facet and keeping the elements denser on the appropriate surfaces. Does anyone have any thoughts on this matter?

Thank You,
Colin Power

as everything, it strongly depends on what you simulate and how. For
example, how many other particles you have, how big they are compared to
the facets etc.

If you only need it for postprocessing, just refine it in the
postprocessing stage if increasing number of triangles becomes a problem :-)
