Hello all

As part of my PhD project which involves CFD numerical modeling, I'm trying to create a geometrical model of a plastic bag around 5 balls.

Is there some way I can model 5 balls and then wrap a geometry around them. Ideally I would like to make as simple a model as possible and it is my aim to define the bag as a surface plane (boundary layer in CFD software) and the balls as solid volumes.

Hope someone can help me?

Here are some instructions. I really hope I interpreted your intent correctly. Let me know if you have any questions about any of the steps.
