Bembel Project – A Boundary Element Method Based Engineering Library

The boundary element method (BEM) or method of moments (MoM) is a common approach for the solution of partial differential equations (PDEs) in engineering applications such as acoustic and electromagnetic scattering problems in homogeneous media. It is accepted in industry and there are many free and proprietary implementations.

Bembel is the Boundary Element Method Based Engineering Library written in C++ to solve boundary value problems governed by the Laplace, Helmholtz or electric wave equation within the isogeometric framework. The software is freely available (as in speech) and it is developed in a joint project of the Technical University Darmstadt, University of Basel and Università della Svizzera italiana in Lugano. More information can be found in the recent software publication 10.1016/j.softx.2020.100476.

If the name rings a bell, a bembel is also a traditional German ceramic:

Most establishments also serve Apfelwein by the Bembel (a specific Apfelwein jug), much like how beer can be purchased by the pitcher in many countries. The paunchy Bembel (made from salt-glazed stoneware) usually has a basic grey colour with blue-painted detailing.
