This is a short presentation of the freefem++ software. In Section 1, we recall most of the
characteristics of the software, In Section 2, we recall how to to build the weak form of a …

Research into the use of unstructured mesh methods in oceanography has been growing
steadily over the past decade. The advantages of this approach for domain representation …

We first describe the well-established unstructured mesh generation methods as involved in
the computational pipeline, from geometry definition to surface and volume mesh …

A new non-iterative mesh generation algorithm named conforming to interface structured
adaptive mesh refinement (CISAMR) is introduced for creating 3D finite element models of …

We propose a numerical method to approximate the solution of second order elliptic
problems in nonvariational form. The method is of Galerkin type using conforming finite …

A new anisotropic mesh adaptation strategy for finite element solution of elliptic differential
equations is presented. It generates anisotropic adaptive meshes as quasi-uniform ones in …

In this paper, we study the extension of anisotropic metric-based mesh adaptation to the
case of very high-order solutions in 3D. This work is based on an extension of the …

In this article, a high-order solution-based mesh adaptation method is investigated. This
later, which is called the log-simplex method, relies on the approximation of high-order …

The paper studies several approaches to numerical integration over a domain defined
implicitly by an indicator function such as the level set function. The integration methods are …

Capturing accurately and automatically the complexity of the whole flow around a complex
aircraft is still an unachieved goal in aerodynamics. Indeed, the various features of the flow …
