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 […]

In last month’s Tips and Tricks article AltaSim introduced the topic of model parametrization, describing the process and a few of the benefits. Effective parametrization of a model file takes time and thought to implement correctly. This article will extend the approach discussed in Part 1 to include one important recommendation for robust geometric parametrization.

When learning to use a simulation software such as COMSOL Multiphysics, users typically focus on learning the fundamental tools and steps for building a model and getting results, e.g. geometry building, applying boundary conditions, defining material properties, meshing and post-processing. These skills are crucial for developing a working and useful model, so it is a great place to start. Once a user has acquired these basic skills for getting a working model, AltaSim

Engineers have been using models since the beginning of time. Computational simulations provide a better way for engineers to model. Computational simulation continues to provide excellent value throughout the product development lifecycle. This engineering tool has significantly improved product quality, development cost and time-to-market for companies. In addition, engineers have used simulation to create highly

Frequency domain simulation techniques are widely used to analyze the behavior of arbitrarily shaped objects and complex materials. One of the disadvantages of traditional frequency domain techniques, however, is the computational cost involved in obtaining solutions over a range of frequencies. Simulations have to be repeated at each frequency of interest to obtain a complete
