Download a free Lite Version
of ENVI-met V4.4
WINDOWS 7, 8/8.1 or 10 64Bit
ENVI-met can be installed on 32 Bit Systems but large models (above 200×200) probably will not work due to memory shortage
3 GB Memory and 1 CPU core for each active simulation, a lot of disk space (expect 5 GB for one 24-hrs Simulation).
ENVI-met might run in a virtualized environment, but calculate slower and will need non-standard settings.
The Winter Release usually brings new features to the system while the Summer Release is mainly dedicated to small updates and bugfixes.
Users of the Lite Version must update to the newest versions within one month. In addition, there will be “Hot Updates” available if required to those who can’t wait for the next official release.
The license conditions depend on the version of ENVI-met you use. You need to agree to the exact and actual license conditions when installing ENVI-met. A general overview can be seen here.
