'''COMSOL Multiphysics''' is a cross-platformsimulation [[finite elementsoftware]] analysis,package solverfor andperforming [[Multiphysics simulation|multiphysics simulations]] and cross-platform [[simulationfinite softwareelement]] analysis and solution finding. ItThe software allowsfacilitates conventional physics-based user interfaces and coupled systems of [[partial differential equation]]s (PDEs). COMSOL provides an [[Integrated development environment|IDE]] and unified workflow for electrical, mechanical, fluid, acoustics, and chemical applications.
Beside the classical problems that can be addressed with application modules, the core Multiphysics package can be used to solve [[Partial differential equation|PDEs]] in [[Weak formulation|weak form]].
