How to Use the Boundary Element Method in Acoustics Modeling

March 19, 2018

Learn advantages and strategies for using the boundary element method (BEM) for acoustics modeling. Plus, we go over a hybrid approach that combines BEM with the finite element method (FEM).

Using the Inflow Boundary Condition in Nonisothermal Flow Simulations

March 15, 2018

Nonisothermal flow is a multiphysics problem, as it combines CFD and heat transfer analysis. Learn how to implement the Inflow boundary condition when simulating these types of scenarios.

Modeling Phase Change in a Thermosiphon

March 12, 2018

A guest blogger from Noumenon Multiphysics writes about modeling phase change in a thermosiphon, a device that has been keeping houses warm since the 1800s.

Advancing Additive Manufacturing with Sequential Simulations

March 7, 2018

In some ways, additive manufacturing is like sewing or weaving. We talk to a professor of additive manufacturing about how sequential simulations can be used to analyze and optimize the process.

Analyzing Triaxial Testing Methods for Geomechanics

March 5, 2018

Triaxial testing of soil is important when determining the structural stability of a tunnel, dam, or building. Geomechanics simulation can help ensure that triaxial testing methods are up to par.

Acoustic Topology Optimization with Thermoviscous Losses

February 28, 2018

A guest blogger from GN Hearing discusses including thermoviscous losses in the topology optimization of microacoustic devices, such as hearing aids, mobile phones, and metamaterial geometries.

Comparing Static and Dynamic Wall Heat Exchangers with Simulation

February 27, 2018

We compare the performance and efficiency of static and dynamic compact wall heat exchanger designs using fluid-structure interaction.

Analyzing Vehicle Suspension with Multibody Dynamics Modeling

February 20, 2018
