Features
Waveller simulates the pressure field in three dimensional space. The computational domain can consist of materials with different acoustic properties. All wave phenomena are taken into account, including standing waves, reflections and refractions. The simulation geometry or the mesh can be imported in variety of formats (including IGES, STL etc.)
The pressure fields are modelled by solving the frequency-domain wave equation (Helmholtz equation) in inhomgeneous absorbing media. The solution is computed using the ultra-weak variational formulation (UWVF). The UWVF has similarities with the standard finite element method. The main differences between UWVF and finite element method are that UWVF uses physical basis functions (plane waves). This reduces computational load dramatically as compared to standard finite element method (see benchmark section). The mathematical formulation and model problems for the UWVF can be found from the scientific papers in the publications section.Different source types from point source to complex vibrating structures can be included into the model. In addition, Waveller provides a full set of boundary conditions, sound-hard, sound-soft, and mixed conditions to take into account the detailed behavior of waves on the boundaries of the simulation geometry. Furthermore, the state-of-the art absorbing boundary condition perfectly matched layers (PML) is also available in Waveller. When infite volume simulations are needed, the standard absorbing boundary condition can cause reflection to the simulation volume. With PML these (unphysical) anomalies can be minimized.
Waveller Acoustics can be run from the command-line using text files to describe the simulation parameters, or in conjunction with Comsol Multiphysics. When using Waveller Acoustics with Comsol Multiphysics, the simulation geometry and simulation parameters are described using the Comsol Multiphysics graphical user interface, and simulation is run using the Waveller computation kernel.
The Waveller computation kernel runs on Linux platform on one or multiple processors. It is fully parallelized for use in Beowulf type clusters for large-scale simulations. The parallelized version is built so that the computational load between the individual processors is balanced to speed up the computation.

Waveller ElectromagneticsThe 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.
