- StarCCM's built in Design mangager is difficult to setup and unreliable
- Automatic resource handling to parallelize running simulations on any number of nodes
- This allows us to better suit our avaliable HPC resources
- Allows for much better error handling and logging
- Can use whatever DOE method works best for us
