Hello,

I am performing static analysis and after meshing I have less mass of component then the reality. i.e. I get 0.8 kg instead of 1 kg. 

To add mass to component, I would select all the nodes and distribute mass evenly.

 

But I wanted to ask if there is easier way then this? for Example, just select the component and give mass and hypermesh will automatically divide to each node of the component. So that I don't have to count the nodes and divide them manually.

 

Thanks in advance.

    are you using optistruct?

    it is already very easy way, if you do for 1 comp, it takes only 10 seconds

    if you have to do for many comps , make a tcl script

    Hi,

    You can also try adding non structural mass in NSM option of PSHELL card, which assigns nonstrictural mass per unit area. Please go through the Help on the same.
