+ | Starting with V4.3, you might also simulate a (very) large area, but you need a (very) strong computer and a lot of memory. | ||

- | There are papers about photocatalytic NO degration, water spray cooling or the cool TreePass. Where are they in my version? | + | |
- | !!! There are 3 different versions | + | !!! ENVI-met is a pure physical model. It was designed for high-resolution simulations, |

+ | !!! There is a large number of documents, online help and video tutorials on our web page and it is growing constantly. | ||
+ | In addition there is our online forum, but remember that this is not an online hotline. Some question might be answered, others not because they are too complex. Also this is intended as an exchange forum between users. | ||

+ | * Try to clean up your model and only keep important structures. But these structures then must make sense. Example: A narrow path between buildings might be close to the models resolution. If you think, this path is important, include it in your model and make it a free path, even if it might be broader or larger in the model than it actually is. If it is not important, delete it. There is no sense in keeping some mess of grids just because the algorithm or map adjustment suggests it. | ||
