How to assign inertia to a node?

Altair Forum User

Hi,

 

    I want to do modal analysis of engine & fixture assembly. I'm gonna consider engine as a rigid point mass, so i will create a node representing engine and i will assign inertia (Mass, Moment of inertia) to that. Subsequently  i will connect the point mass to fixture mounts through rigids. I don'no how to assign inertia values to node. Any help regarding this will be of great help to me...

 

Thanks!!!!

After creating mass element (CONM2), card edit the element as below,

 

<?xml version="1.0" encoding="UTF-8"?>

 

Now, click on the CONT option to input the inertia values:
