How to include the own weight of the element

Altair Forum User

Hi Guys

I am working on my school project

I tried to include the own weight of the elements in my calculations but they didn't look alright.

That is what I did.

1- I defined RHO in the materila MAT1 card.

2- I created a Gravity load collector with Given values for G and (-1) for z

3- I created a loadstep that includes the Constrain = load collector, Gravity = Gravity load collector and extrenal load = load collector collector

Is this the right procedure

Please let me know with details

Bashar,

You need to combine the gravity load with the external loads using a LOAD Bulk Data entry, and then reference this in the subcase using the LOAD data selector.
