PALM Tutorial

This tutorial teaches you about the design of PALM, and how to ... carry out runs with PALM for different meteorological scenarios. use specific parts of the model, such as the embedded particle model or topography. understand and analyze the PALM output data. add user-defined code to the model. debug errors. At least once a year, we are hosting the 5-day seminar An Introduction to the Large-Eddy Simulation Model PALM, which covers all the above-mentioned topics (Class of 2018 in Fig. 1).

If you cannot make it to the seminar, you could self-study the contents by following the time schedule of this years' PALM seminar (Fig. 2). The respective PDF presentations are available as attachments below (normal and handout version). At the PALM seminar 2019, we are going to work with PALM revision number r4151. The PALM code is currently under heavy development (see lecture "Current developments"). To view the code changes since then, feel free to browse the repository, or have a look at the changelog.
