How to obtain the mass moment of inertia

Hi! I need to find the moment of inertia of a complex structure. Anyone knows a way to calculate it? I took a look at the forums but the info I saw was very confusing. Thanks a lot!

Re: How to obtain the mass moment of inertia

Hi Ezequiel, If you integrate the density over a domain you get its mass. Similarly, if you integrate “density * (x^2 + y^2)” over a domain you get its mass moment of inertial about the z-axis, I_zz....

Re: How to obtain the mass moment of inertia

Hi in the latest 4.4 you can add a sub-node in the "Definitions" section (as for old v3.5) and get a set of variables defining mass, Cog, moment of inertia etc very handy But do not forget to define...
