- You could always use a remote or distributed mass (depending on what you're after).
- If I recall correctly, you can't have more than one gravity load defined, but I'd wait to get someone more knowledgeable to confirm that. This is unfortunate (if true), as it's a lot more efficient to solver a stiffness matrix once with multiple load sets (instead of multiple times with one load set each).
- Not sure if the override mass value works in simulation, so you maybe use (1).
overridden masses don't get carried over to simulation you'd have to add a remote or distributed mass in simulation to do something similar.
on applying multiple gravities, you can't do more than 1 at a time but if you expand the advanced options you can add other directions if you want.
but i don't think i really understand what the load application is. but you can do it if you want.
Another trick you can use to quickly create and solve different studies at once is to copy-paste the studies. Modifying the G loads and then solve them all at once in batch. Use the "Run all studies" option.
Thanks for sharing the tips. It's more clear now.
