The most significant limitation is the grid domain restriction: simulations are limited to a maximum of 50 x 50 grids. This means you can analyze a single building, a small street canyon, or a modest public square, but not an entire district or city. The free version also restricts some advanced calculation features, such as Full Forcing meteorology and multi-core computing support, which is typically reserved for paid licenses. However, it is important to note that you can adjust the grid resolution (dx, dy, dz) within the free version, so a 50x50 grid is still capable of providing detailed insights for many small-scale projects.

In that case, purchase a license or switch to open-source alternatives like UMEP or OpenFOAM.
