I want to create a "dummy" part outside my cube and i want to use that area as local initial size , in order to calculate the drag force on a 2D and a 3D cube.
Also can i create multiple "dummy" parts around my cube ? For example i want to make two initial local (one inside the other).
1.Does anyone have some detailed steps in order to do that ?
2. How can i achive a specific cell size in that area ? For example i want all the area around the cube to be 0.1m cell size. Is that possible ?
Thank you in advance.
