Description

MolFlow+ is a test-particle Monte Carlo code for ultra-high vacuum simulations, primarily intended for use in the field of particle accelerators. This contribution gives an overview of updates made to the code in recent years. The graphical user interface has been improved and several new features have been added, including a tool for extracting simulation results along user-defined 3D paths, as well as automated scaling of the desorption rate when recording molecules' directional distributions. Additionally, the code can now count the number of particles present on a surface within a specified time window. Furthermore, the calculation of particle residence time (sojourn time) has been updated to allow for temperature variations during a particle's residence on a surface. This enables simulations of surface decontamination through heating (bakeout). Finally, MolFlow+ can now simulate particle collisions with background gases using the hard-sphere collision model.
