Abstract: Snow avalanche dynamics is a phenomenon widely studied worldwide. Modelling of avalanche dynamics require several conditions: 1. appropriate software, 2. digital terrain model, 3. photography or local measurement of snow properties in the area of interest, 4. weather and snow forecast to evaluate snow deposition in the terrain, 5. entry and boundary conditions. There are several dedicated software for snow crack propagation, snow avalanche dynamics, etc. Most of these software are not available as freeware and their full and educational licenses are quite expensive for personal, research or educational use. On the other hand, there are general simulation software packages covering multiphysics that are available as academic campus licenses with tens of licenses per individual physics. These academic campus licenses are widely spread for academic purposes at universities and research institutes. Thus, many undergraduate, graduate and Ph.D. students have access to the enterprise versions of Computer Fluid Dynamics (CFD) software. The fifth generation of Digital Terrain Model (DTM 5G) representing natural and human modelled terrain in a form of discrete points is currently available in many countries. As the total mean error of the height in DTM 5G is 0.18 m in an open terrain and 0.3 m in a forested terrain, it could be used for modelling snow layers and avalanche dynamics without additional unmanned aerial vehicle (UAV) Light Detection And Ranging (LiDAR) or satellite data. In our contribution we focus on the application of campus license of CFD solver Ansys Fluent for modelling avalanche dynamics in typical avalanche paths in the mountains with comparison with real avalanches.
