pyblockmesh

Python Library

Example

import pyblockmesh as pbm


v0 = pbm.Vertex(-1,-1,-1)
v1 = pbm.Vertex( 1,-1,-1)
v2 = pbm.Vertex( 1, 1,-1)
v3 = pbm.Vertex(-1, 1,-1)
v4 = pbm.Vertex(-1,-1, 1)
v5 = pbm.Vertex( 1,-1, 1)
v6 = pbm.Vertex( 1, 1, 1)
v7 = pbm.Vertex(-1, 1, 1)

h1 = pbm.Hexahedron([v0,v1,v2,v3,v4,v5,v6,v7],numberOfCells=[3,3,3])
h1.add_edge(v0,v1,'line')
h1.add_face([v0,v1,v2,v3],name='inlet',patchType='wall')

string = pbm.buildBlockMesh()

print(string)
blockMeshDict = open("blockmeshdict.txt", "w")
blockMeshDict.write(string) 
blockMeshDict.close()
