Like always, ENVI-met V4 is free and comes along as a complete model including the full set of features. In addition to the free version (“ENVI-met Standard”), there is a Professional version with additional analysis modules and an Expert Version with advanced modelling features. The diagram below summarizes the basic differences between the 3 versions:

While the Standard version can be downloaded and used freely, the Professional version must be licensed for an individual user or a academic institution. For more information, please write an e-mail to office[at]envi-met.com. Finally, the features of the Expert version are only available within our consultancy work.

The documention from V4 is not ready yet. Most of the general itmes of V3.1 can still be used, but there are considerable differences in details. A short overview can be found here.
