triqs.mesh.meshes

Different mesh types provided by the TRIQS library.

Each mesh class discretises a one-dimensional (or, for MeshBrZone and MeshCycLat, multi-dimensional) domain and provides the index ↔ data-index ↔ value mappings used by the TRIQS Green’s function containers.

The mesh classes may be categorised as follows:

• Function space meshes: MeshDLR, MeshLegendre.

• Imaginary time and frequency meshes: MeshImTime, MeshImFreq, MeshDLRImTime, MeshDLRImFreq, MeshChebyshev.

• Real time and frequency meshes: MeshReTime, MeshReFreq, MeshReFreqLog, MeshReFreqPts.

• Lattice meshes: MeshBrZone, MeshCycLat.

These classes are wrapped from their C++ counterparts in triqs::mesh and are re-exported at the package level under triqs.mesh.
