In your case your planning to run FEA or CFD.
1. In case if your planning to run CFD with different iterations, then you can prepare with all Boundary condition and goal, then you can use to run all CFD with batch run option.
2.In case of FEA, then prepare different Iterations with all boundary conditions and loads. Then use run all Study option.

Here is a cool tip that I didn't know until a couple of years ago
Assuming that you're using flow simulation if you have simulation multiple files, if they are all open the batch run will let you run simulations from any of the files
If you want to batch run like that for simulation, you can also look at task scheduler
