Domain & resolution

First you should decide if your final(!) simulation (see "Cascading" below) should be on a regional or a global grid and at which resolution you want to run. For this it is important to know that:

• the more grid points a grid has, the more cores are needed and
• the smaller the resolution and with that the model timestep the longer the simulation will take.
