Estimating the volume affected by a temperature

Hi COMSOL users,

I have a question that has been driving me crazy for a while now. I'm doing a simple heat transfer model and I'm trying to estimate the volume that is above a certain temperature threshold. I saw in post processing there is a volume plot and I set the minimum and maximum values appropriately. I was wondering if there is any way to extract to volume of the geometry this way. Thanks!

Dear Alexander,

You can do a volume integration of (T>300) to get the volume of the domains with a temperature larger than 300 K. The logical operator supplies 1 if true, and 0 otherwise (try to plot it in a 3D volume plot)

I hope this solves it for you.

Best regards,
Frank

Thanks so much!

I wasn't aware I could input a function there!
