Yesterday August 13th, 2018, R-SWMS developers from Germany and Belgium met in Liège (BE) to set up a new version of R-SWMS. The former one was 8.2. The new version, called R-SWMS 9.0, has several new features. Now, it is possible to simulate multiple root systems with different transpiration and growth, peticide uptake and transport in the plant and root growth in the biopores. Techical changes have also been implemented like the parallel processing for solute transport with particle tracking or the possibility compile only water flow (without solute).
