Simulation on uneven terrain

[sujinlee]

Modules installed on flat terrain have one orientation, making it easy to simulate.

However, modules installed on uneven terrain have more than one direction and module angle, so you need to set multiple directions, but I don't know how.
I would appreciate it if you could explain how to simulate the installed module according to the shape of the terrain.

If you have a single nominal orientation, the simplest is to use the window "orientation management" to identify all effective orientations as a single nominal one.

You will find this window from the 3D scene view > Tools > Orientation management tool. Once there you can adjust the tolerance and "identify orientation", the goal being to define a single orientation. This will also give you some information about the largest deviation in effective orientations in your scene.
