Vizir

Vizir is a mesh modification and visualization tool. It includes:
  • Curved high-order mesh visualization
  • Hybrid mesh visualization (pyramids, prisms, hexahedra)
  • Local display of meshes: mini-mesh, fast search of entities: vertices, edges,
  • See Gallery page for other examples of rendering

Feflo.a | Lib

Feflo.a is an robust anisotropic local remeshing sotware. Surface and volume mesh adaptation are handled in a coupled-way. It also includes boundary layers mesh generation for RANS simulations. It includes:
  • CAD re-projection and discrete surface remeshing
  • Hybrid mesh generation for boundary-layers
  • High-quality quasi-structured grids for complex geometries and complex corners: multi-normals, normals deactivation, ...
  • Highly anisotropic mesh adaptation, ratios: O(1:1000)
  • Anisotropic/Boundary-layer coupling for supersonic shock/boundary layer interaction
The boundary layer module alone (abl4flo) is registered with the APP under nbr. IDDN.FR.001.080032.00.S.P.2012.000.10000
The mesh adaptation module alone (ama4flo) is registered with the APP under nbr. IDDN.FR.001.460014.000.S.P.2012.000.10000
  • All examples of the Gallery page have been using Feflo.a for the generation of the anisotropic meshes.

AMG-Lib is the Adaptive Mesh Generation Library based on the Feflo.a technology. Its intent is to ease coupling with external flow solvers. See examples with Stanford SU2 code on the Git Hub Wiki.

Metrix

Metrix is a software that provides by various ways metric to govern the mesh generation. Generally, these metrics are constructed from error estimates (a priori or a posteriori) applied to the numerical solution. Metrix computes metric fields from scalar solutions by means of several error estimates: interpolation error, iso-lines error estimate, interface error estimate and goal oriented error estimate. It also contains several modules that handle meshes and metrics. For instance, it extracts the metric associated with a given mesh and it performs some metric operations such as: metric gradation and metric intersection.

Metrix is registered with the APP under nbr. IDDN.FR.001.070014.000.S.P. 2009.000.10000

Shrimp

The main issues addressed by are the reduction of cache misses by mesh renumbering, the improvement of shared memory parallel machine by mesh renumbering and domain splitting for parallel runs on distributed memory parallel machine.
  • Parallel hilbert renumbering
  • Parallel partitioning suited for parallel mesh generation
  • Creation of connex partitions
