Integration on different expressions of the same surface giving different...

Hello, I am hoping that someone can help me with a problem I am encountering in attempting to measure mass flux in my fluid dynamics simulation. I am getting very strange and different results when...

Re: Integration on different experssions of the same surface giving different...

Hi You talked about probable units issues, by default, even if your geometry is in [um], the coordinates x,y,z are in SI or [m] by default so "(59<x)" means "True if x smaller than 59[m]", and you...

Hi Ivar, Thank you for your reply. Adding [1/μm] to the variables in the boolean restrictions for the cut plane gives a syntax error, but I have appended "e-6" to all of the numbers and am now getting...

It turns out that the order of magnitude error on the parameterized surface was a bug fixed in the latest update. I thought comsol was up to date, but apparently there was an error with updating....
