calculation errors in comsol
Dear all,
Does anybody know how to estimate errors in calculations caused by mesh size.
Thanks in advance,
Alex

Re: calculation errors in comsol
Hi Alex
my way is to refine once, resolve and compare the results, but smethimes the errors are very local (stress concetration or E field concetration around sharp edges) then an adaptive meshing refinement is often better than a global refinement
Thre should be a residual variable somewhere too, check in the doc
Good luck
Ivar
