Web4 jul. 2024 · For condensed systems, the incorporation of quantum chemical solvent effects into molecular dynamics simulations has been a major concern. To this end, quantum mechanical/molecular mechanical (QM/MM) techniques are popular and powerful options to treat gigantic systems. However, they cannot be directly applied because of temporal … WebPyroSim includes tools to manage multiple meshes. One effective strategy is to first define a single mesh that spans the entire model. Then use the PyroSim mesh splitting tool to create multiple meshes. You can then change the resolution of selected meshes using the Refine Mesh option and all the meshes will automatically stay correctly aligned.
