9 What is a model of blocks ?
10 ===========================
12 A block (or a hexahedron) is a volume defined by:
15 - 6 quadrangular faces
17 A model of blocks is a set of blocks.
19 And for each quadrangle of a model of blocks, this quadrangle is:
21 - or a face shared between 2 blocks
23 How to find a model of blocks ?
24 ===============================
26 In this version of HEXABLOCK component, the user must find himself the model of blocks that is adapted for his geometry.
30 How to create a model of blocks ?
31 =================================
33 When the user find the model of blocks necessary for his geometry to be meshed with hexahedra,
34 HEXABLOCK component has a lot of tool to build this model of blocks:
37 - create one hexahedron
38 - create a hexahedra with 2, 3, 4 or 5 quadrangles
46 - predefined model of blocks:
49 - for two intersected cylinders
50 - for two intersected pipes
54 - powerfull functions:
57 - make hexahedra by revolution of quadrangles
58 - cut an edge to slice hexahedra
59 - replace an hexadron by a pattern
