Finite-element-software Comsol Multiphysics 3.3 allows simulating a wide variety of physical phenomena. An analysis of heat transfer in a V-Twin motorcycle engine block shows the surface temperature distribution in degrees Kelvin. The PDE Coefficient Form, one of Comsol's most flexible methods for solving a PDE, is being implemented to solve a problem with Fluid-Structural Interaction (FSI). The red lines indicate particle traces for the fluid flow. Finite-element-software Comsol Multiphysics 3.3 allows simulating a wide variety of physical phenomena. In fact, the program can model just about anything that can be described mathematically. It includes equations for some of the most common problems such as stress analysis, fluid transport, heat transfer, and mass diffusion. Users can also type in the governing partial differential equations (PDEs) for problems that describe phenomena not already included in the software. What really sets 3.3 apart, however, is that it allows coupling various equations together to solve multiphysics problems. A simple example comes from a problem involving thermal-induced stresses in a machine part. A more complex example is a hydrogen-fuel cell, which involves simultaneous mass transport by way of diffusion, fluid flow, and electrochemical reactions. Users can quickly modify governing PDEs to suit their needs. For example, after learning how to do a simple conduction heat-transfer analysis, a user can, in a matter of minutes, modify the equations to account for spatial and time-varying thermal conductivity throughout the part. All it takes is simply specifying a mathematical function to describe the parameter's variation. Many FE programs do not have this feature. Comsol is flexible enough to model just about everything from the deformation of nonlinear material to species distribution and concentration in a stirred reactor vessel. The program's graphical environment lets users model 2D or 3D geometry, mesh it, apply boundary conditions, and solve the problem. It's
