Wave Simulator for Acoustic Computing

Introduction

Waveller is a powerful Helmholtz-equation solver that is controlled using it's own input data format. Converting meshes and setting simulation variables has been a tedious task until now. The solver is implemented as a plug-in to a widely used engineering software, Femlab. Simulation geometry can be created and simulation material parameters set using Femlab's graphical user interface, and this information is exported to the Waveller plug-in, which in turn computes the resulting acoustic field using the UWVF-algorithm. The result can be visualized and further post-processed using Femlab's versatile post-processing facilities.

Ease of use

Using the plug-in, the user doesn't need to concentrate on the details of the Waveller solver. Instead, the time is spent on the actual design of the geometry and it's properties and evaluating the results. The workflow when using the plug-in is exactly the same as when using the standard Femlab.

Simulation benefits

The Waveller solver has been benchmarked and compared to standard finite element method (FEM) solvers (see Benchmarks). The key benefit is that Waveller uses considerably less time and memory to compute the same wavefield compared to standard FEM solvers. The user gets the result faster and is able to model larger volumes and more detailed geometries with even higher frequencies.

Femlab cluster-enabled

Not only Waveller is a superior solver on one processor -- with the Waveller cluster plug-in the user is able to model large-scale simulations using Femlab as a front-end. Beowulf-style commodity hardware clusters provide a cost-effective solution for simulations requiring tens of gigabytes of memory, and with the cluster plug-in Femlab can utilize this increased computing power. The usage of the cluster plug-in is equivalent to using the single processor plug-in, data transfer between the front end (Femlab) and cluster is done automatically.

Schedule

Both the single processor and cluster plug-ins are scheduled for release in November 2005. For more information and technical details, please contact us at info@waveller.com.

Waveller Electromagnetics
The first results using Waveller Electromagnetics are available in article Solving Maxwell's Equations Using the Ultra Weak Variational Formulation and in the screenshots-section. The mathematical formulation of Waveller Electomagnetics is extremely useful for solving electromagnetic field related wave problems in many application fields. We are currently seeking collaborators for developing a COMSOL plug-in for Waveller Electromagnetics.

Our development efforts have concentrated on implementing Waveller as a plug-in solver to Femlab. This enables the user to create or import geometries using Femlab's GUI as well as setting material and solver properties, then using Waveller to compute the result, and finally to visualize the result using Femlab's versatile plotting options. More information is available on Femlab plug-in-section.
