BLSURF

BLSURF is a CAD (composite parametric) surface mesher. The mesher can be plugged to a CAD platform or used as an external module. In the first case, the surface evaluation with derivatives must be provided.

As an external module, two CAD formats are taken into account, namely IGES and STEP files.

PLOUGH3D

The PLOUGH3D software generates the triangulation of a given discrete level set of an implicit surface.
Such a grid is often called a "voxel" grid which can be defined in two different ways:

  1. A 3D grid of real (scalar) values.
  2. A set of grayscale images.

The first concerns the values of a given analytical function and the second, images obtained via digitalized scans such as "CT scan" or "MRI scan".
The software also produces a closed surface of a given thickness around the imposed level. This kind of triangulation is particularly useful for surface 3D printing.

Industrial partnerships (since 2020)


SAFRAN/COMPOSITES  

The partnership with Safran/composites concerns the geometric modeling and meshing of three-dimensional composites. The initial geometry of the structure is defined by a 3D reconstruction from 2D scan images. The research developments include the definition of a parametric geometry and the construction of meshes of the structure. Eventually, these composites will be integrated into mechanical parts in order to establish their behavior models. The partnership has led to the development of several software programs under Safran/composites license.
 

DASSAULT AVIATION

The collaboration with Dassault Aviation goes back several years. The main research topic concerns the generation of hybrid surface meshes. Such meshes are used for various applications (fluid dynamics, shape optimization...). In addition, we are interested in the extraction of geometric or physical characteristic lines and surfaces. This partnership has led to the training of several PhD students, the development and licensing of several softwares.
 

CEA

The main research topic concerns the modeling of the behavior of three-dimensional granular structures in large geometric deformations. In this context, an advanced computational scheme including a complete chain processing (remeshing, error estimator, field transfer...) is achieved. The current research concerns multiphysics and multimaterials. In the framework of this partnership, several software licenses, including our 3D remesher, have been granted.
