Does the Current Flow Backwards Inside a Battery?
What happens inside a battery? Does the current flow from negative to positive electric potential? Here, we explain the potential profile inside a battery during discharge and recharge.
Different Ways to Count Particles in COMSOL Multiphysics
There are 3 ways you can count particles in your particle tracing simulations in COMSOL Multiphysics: during postprocessing, using accumulators, or with the Particle Counter feature.
Exploiting Periodicity in Models with High Péclet Numbers
In the study of chemical species transport, a high Péclet number means the ratio of advection to diffusion is very high. Learn how to exploit periodicity when modeling this type of problem.
How to Solve for the Brachistochrone Curve Between Points
See how to use built-in mathematical expressions, the Optimization Module, and COMSOL Multiphysics® to solve for the brachistochrone curve.
How to Calculate Mass Conservation and Energy Balance
Ever wonder how to compute the mass conservation of a fluid flow simulation, or the energy balance of a conjugate heat transfer simulation? If so, keep reading >>
Modeling Acoustic Orbital Angular Momentum
Get an introduction to acoustic orbital angular momentum and a demonstration of how to model it. Parr 2 of a blog series on modeling acoustophoretic forces.
Modeling Microresonators with Electrostatic Actuation
Learn how to model electrostatically actuated MEMS resonators and get an intro to terms such as equilibrium point, pull-in, pull-in voltage, and time harmonic response of a biased resonator.
Modeling Linear Motors or Generators in COMSOL Multiphysics
We demonstrate how to customize a linear periodic boundary condition to model linear motors and generators in COMSOL Multiphysics®, with an example of a tubular generator used for wave energy.
