 When you start to get in touch with ENVI-met, you should build **small** models, e.g. in the size of 30x30 grids. These models will run very quickly and you will get your results very soon. You will also get back negative feedback very soon, if your model cannot be simulated properly due to the selected settings or other issues. When you start to get in touch with ENVI-met, you should build **small** models, e.g. in the size of 30x30 grids.

-As you run simple simulation, you will more and more understand how the system works and which are the triggers and settings you need to modify to control your simulation. You will also see, that a numerical climate model is a highly non-linear system. Small issues, uncertainties or changes can lead to large changes or problems in the overall simulation, which is the famous [[wp>Butterfly_effect|Butterfly Effect]] in [[wp>Chaos_theory|Chaos Theory]]. +As you run simple simulations, you will more and more understand how the system works and which are the triggers and settings you need to modify to control your simulation.

 As a matter of fact, ENVI-met is not a "normal" computer program, in which every action has a clear result and the failure to produce a result or an error message is a software programming failure. In many cases, you will need a lot of thinking and analysing, why the model results are as they are. Besides a feeling for numerical models, this also requires knowledge in microclimate and atmospheric physics. As a matter of fact, ENVI-met is not a "normal" computer program, in which every action has a clear result and the failure to produce a result or an error message is a software programming failure.

 When you run large models, you will occupy your computer, or at least parts of it, for a long time. Although -depending on your PC- it might be possible to run even large ENVI-met simulations on your PC and keep on using it for your daily work at the same time,  this is not recommended. It will significantly slow down both the ENVI-met simulation and your daily work. When you run large models, you will occupy your computer, or at least parts of it, for a long time.

-Best choice is to have an own computing PC reserved for your ENVI-met simulations. Once installed, it doesn't require its own keyboard or monitor and you can access it through Remote Desktop programs. The only thing you need to di is to copy your ENVI-met files onto the calculation PC and copy back the results once they are finished. (And, in additon, you should check from time to time if your simulation is still running...).+Best choice is to have an own computing PC reserved for your ENVI-met simulations.
