How to apply force on the centroid of a solid object?

I want to simulate the effect of Gravity on Object.

I already create one coordinate system that origin is the centroid of solid object.

Is there something stopping you from using Inertial loads with standard Earth Gravity which is straightforward?

Let me describe the situation.

My simulation is to simulate the effects of gravity on non-vertical objects.

I want to simulate the effects of gravity on objects with different deviation angles without changing the model.

Is there any way to finish it?

You can set the direction of gravity and adjust it by degrees from one angle to another about the model, without any other change to the model.

First create a new Coordinate System. I renamed it to add for gravity. Use Global Coorinates for the Origin, then click on the RX button in the Coordinate Systems toolbar and type an angle to Rotate X.

Click on Static Structural, on the Environment toolbar, click Inertial, Standard Earth Gravity. In the Details window, change the Coordinate System to the one you just created and renamed. You can pick which Direction you want.
