There are three codes available on this site. UCLCHEM is a gas-grain time-dependent chemical code. 3D-PDR is the first fully 3D code for PDR regions. For more simple models, a 1D version called UCLPDR is available. Links for each code are above and the individual pages for each code have full descriptions and links to the code repositories and manuals.
