Efficiently Verify Electric Fields Outside Electrical Installations with Apps

Bridget Cunningham February 8, 2017

Electrical installations are required to have their surrounding electric fields fall within certain levels. A simulation application can be used to verify measurements and adhere to standards.

For patients with renal failure, efficient dialysis treatment is vital. One point of focus is designing high-performance dialysis equipment that increases contaminant removal, improving treatments like hemodialysis. To accomplish this, you can study aspects of the hemodialysis process, such as membrane dialysis devices, with numerical modeling apps. These apps, like the one discussed here, enable users to more quickly analyze the effects of different inputs and improve designs.

Learning how to use computational tools requires training. This is why a large group of stakeholders — one that continues to grow — relies on a small pool of experts to perform simulation analyses. The Application Builder, part of the COMSOL Multiphysics® software, is helping to bridge this gap. Simulation experts can now wrap models in an easy-to-use interface, making multiphysics simulation more accessible to a wider audience. See what our customers have to say about the Application Builder.

For many years, it’s been possible to analyze synchronized CAD geometries in COMSOL Multiphysics® via the LiveLink™ interfacing products. But did you know that you can also incorporate this functionality into an easy-to-use simulation app? With an app, you can dynamically modify your geometry in a CAD program such as SOLIDWORKS® and use this information to analyze new product designs. Today, we will demonstrate how to do so, using the new Bike Frame Analyzer app as an example.

When designing a perforated well to recover oil and gas, choosing the right number of perforations with the appropriate properties is key. Too many holes and you run the risk of equipment failure or injury; too few and you decrease productivity levels. One way to achieve this balance and improve the safety and productivity of the recovery operation is to model fluid flow near the wells. Let’s see how the Application Builder makes this process even more efficient.

In a previous blog post, we discussed the physiological basis of generating action potential in the excitable cells of living organisms. We spoke about the simple Fitzhugh-Nagumo model, which emulates the process of depolarization and repolarization in a cell’s membrane potential. Today, we analyze a more advanced model for simulating action potential, the Hodgkin-Huxley model. We also go over how to use a computational app to streamline this type of analysis.

Aside from the winding type, concentrated or distributed, the logic behind the design of electrical machines is relatively similar, as it’s based on their phasor diagrams. Using an induction motor benchmark model with a concentrated winding, we’ll show you how to create selections in the COMSOL Multiphysics® software to streamline the analysis of your winding design. We’ll then demonstrate how to further advance your simulation studies by automating these processes with the Application Builder.

In 1961, R. Fitzhugh (Ref. 1) and J. Nagumo proposed a model for emulating the current signal observed in a living organism’s excitable cells. This became known as the FitzHugh-Nagumo (FN) model of mathematical neuroscience and is a simpler version of the Hodgkin-Huxley (HH) model (Ref. 2), which demonstrates the spiking currents in neurons. In today’s blog post, we’ll examine the dynamics of the FN model by building an interactive app in the COMSOL Multiphysics® software.
