• Surface Meshing:
o BPs determine where and to what level to refine surface
meshes.
• Volume Meshing:
o Polyhedral meshing (BT) contributes enormously to ease
of volume-mesh generation, accuracy and robustness of
the CFD solution. BPs determine where and to what level to
refine volume meshes. Surface extrusions (BP) are a
necessity for boundary-layer resolution.
o
Multi-Domain meshing (BT) is essential for certain types
of Multi-physics analysis such as conjugate-heat-transfer
(CHT) and fluid-structure interaction (FSI). BPs determine
which domain requires what level of volume meshing.
Continuous and fully connected meshes (BP) ease solver
issues between the multiple domains/physics. See
examples in Fig. 4.5.6.3.
• Analysis:
o Best Practices determine best use of mesh types,
discretisation practices, physical model practices, and
boundary conditions. Dependency analyses are always
encouraged to evaluate, verify and validate the modelling
practices.
