If you set up a simulation at a lower resolution that the final resolution you can get a fast preview of what sort of container size you need. You can then create a cube primitive and resize that to match the sim adaptive container. You can now resize your TFD container and reposition it based on the cube. When you increase the resolution the sim will tighten up so it will not exceed these dimensions. Thus you can get a good estimate of what sort of memory requirements you will need.
