Measure the mass of a domain

Please login with a confirmed email address before reporting spam

Good day May i ask is there any method to measured the mass of a domain? For example, i build a sphere in COMSOL and and need to know the mass of the sphere.

Thanks in advance

Define a domain integration and integrate the density of the domain. If you integrate 1 you get the volume.

Hi,

Also, check out the Mass Properties node under Component>Definitions, where you can define variables for the mass, volume, center of mass, and moments of inertia.

Best regards,
