Multiple gravities

Altair Forum User

Hey there,

 

i got a problem with my optimization. What i want to do is addig 4 gravity loads on my component in various directions.

well i know the option to create a load collector and card edit it to 'grav'. But then i would have to create 4 load collectors and the problem is how to assign 4 loads into my loadcase?

 

So what i tried to do then is just applying 4 forces. Because i know the mass of my component i can easily calculate the force.

so i tried to apply the 4 forces on the whole component with the various directions. But now i get a error # 1000 saying incorrect data in field 3 - 'FORCE 2 0 1.0 0 ......'

 

Perhaps i may have a big fallacy but i just dont know how to solve that problem

 

With best regards

 

EDIT: I think i found the problem but i dont know how to delete this topic

You can use LOAD card to add GRAV loads.

 

Create 4 GRAV load collectors and create one more with LOAD as card image and call these GRAV cards into LOAD.
