Of faces in mesh, nelts the number of elements in mesh. The connectivity cn is made of a faces-to-nodes connectivity (FN) and aĮlements-to-faces connectivity (EF). Of type ‘NGON’, describing meshes made of polyhedral elements. If an stores field on elements, ‘ELTTYPE’ can be ‘NODE*’, ‘BAR*’, ‘TRI*’, ‘QUAD*’, ‘TETRA*’, ‘PYRA*’, ‘PENTA*’, ‘HEXA*’. If an stores fields on nodes, ‘ELTTYPE’ can be ‘NODE’, ‘BAR’, ‘TRI’, ‘QUAD’, ‘TETRA’, ‘PYRA’, ‘PENTA’, ‘HEXA’. Storing the elements-to-nodes connectivity and an is a numpy array of data. The second one is called a pyTree and it implements the CGNS/python standard.Īn array is a simple definition of a mesh using classical numpy arrays.Īn array can be a structured array defined by a python list, where ni, nj, nk are the dimension of the grid and an is a ( nfld, nixnjxnk) numpy array containing data (coordinates and fields).Īn array can also be an unstructured arrayĭefined by, where cn is a numpy array The first one is called an array and is very close to a numpy array, This module can manipulate two different data structures: Pre- and post-processor for CFD simulations. This module is part of Cassiopee, a free open-source This module provides functions for CFD data conversion (both file format
