Using Evaluation Operator in Post-Processing

Engineers post process their simulation results for reasons that range from better understanding their results to communicating those results to others.  Developing labels that clearly identify the conditions for a simulation communicates the critical input parameters for the plotted results. In this Tip and Trick, the simulation engineers at AltaSim will show a way to …

Electromagnetic Wave Polarization in 2D Geometry

An electromagnetic wave consists of a coupled oscillating electric field and magnetic field which are always perpendicular to each other. By convention, the “polarization” of electromagnetic waves refers to the direction of the electric field. In 3D geometry, arbitrary polarization is naturally defined by the prescribing the directions of all three components of the electric …

Selection of Exterior Boundaries

At virtually every step of the model creation process, you need to select and apply materials, physics boundary conditions, and other settings to your model geometry. Bookkeeping of these settings can be challenging, especially when you re dealing with large, complex geometries and multiple physics interfaces. In COMSOL Multiphysics, Selections provides a tool to organize your model …

How to Export Plot Data in COMSOL Multiphysics

Post processing is the last of the five primary steps of simulation development. This step represents the payoff from all the hard work of the previous steps, and it drives the deeper understanding of the design that engineers obtain though simulation. A simulation engineer can significantly improve their understanding, and better communicate that understanding, when …

Data Storage Options for Dynamic Simulations

Many simulations are quasi-static, or steady state, because the results are independent of time.  Time dependent simulations introduce additional challenges over time independent cases.  The data generated during a time dependent simulation could be many gigabytes.  Thus, the simulation engineer needs to balance the volume of output data with their needs for data at critical …
