ENVI_MET Winter Release 2017

We are thrilled to announce the winter release of ENVI-met, ready to run on your desktops and servers. This new release is a game-changer for our company, and we think you’re going to be very pleased with the improvements that will come with it.

Winter release of ENVI_MET

Hoping to make you today a premature Christmas present the new release comes with three major innovations:


  • 64 Bit Support
  • Open & Flexible Domain Sizes
  • Parallel Computing


All three developments of ENVI-met depend on each other, because without the 64-bit support you will not be able to calculate whole city-quarters with ENVI-met. Likewise, you could not shape your ENVI-met domain to your needs without open and flexible domain sizes. And finally, parallel computing is the basic requirement to calculate your simulations in a reasonable time.

All other application have been reviewed as well, the interface of SPACES has been remodelled significantly. New and updated tutorials on the new features will be available on our Youtube-channel, facebook page and homepage within the next days.

Winter release highlights

64Bit Support

On 64Bit WINDOWS Systems (recommended: Windows 10), the ENVI-met core application and LEONARDO are now designed as 64 Bit applications. This means, that the whole computer memory is now available to ENVI-met, removing almost all previous limits of former times.

Open& Flexible Domain Sizes

As the 32Bit memory is no longer the limit to ENVI-met, we have removed the pre-defined ENVI-met Versions (e.g 150×150 or 250×250 Grids). From Version 4.3 on, you can allocate any number and combination of grid cells you like – if you have enough memory available.

Please note that free trial BASIC version is still limited to 100x100x40 grids.

Parallel Computing

Last but not least: ENVI-met now supports parallel computing on your CPU. If you have several CPU cores available, ENVI-met will distribute the calculation work in parallel over the CPU cores. This can result in an overall speed-up of 10 times compared to the previous versions and is the biggest milestone in our development.

Using ENVI_MET for large-scale WUDAPT simulations (TKR)

Since ENVI_MET V4.3 is now able to be run in 64-bit mode and with all processors used in parallel, the model areas used can be sized quite large.  (The right computer presumed)  It is now possible to simulate city quarters in the range of kilometers in a reasonable resolution and time.

The Local Climate Zone Classification of WUDAPT (www.wudapt.org) ) is about to be used as input data for these big model areas. The Local Climate Zones defined by Steward and Oke (2012) classify urban areas and their rural surrounding into 17 types like Compact High-Rise in CBDs, Heavy Industry or Dense Trees (forests). WUDAPT is an open project in which everybody can participate by classifying a city into Local Climate Zones. The satellite-based classification which covers big parts of city can now be used to provide large model areas for ENVI_MET. A small interface generating those model areas using the WUDAPT data as input is developed in the course of a master thesis at the moment. The output of these big ENVI_MET simulations may then consecutively be used as nesting input for further high resolution runs with ENVI_MET (self-nesting)
