No. of elements and nodes generated by
brick mesh are in the order of 1/2 to 1/50 in comparison to tetra
mesh.
Brick mesh reduces solution time and
results in ease of handling the model on workstation (pre and post display).
Time consumed in brick meshing is more
and requires experience, hard work and lot of patience too!
Over the years algorithm for tetra has
improved and accuracy wise there is not much difference in tetra-1 0 and
brick-8 elements.
Analysis types like crash or
non-linear give preference to brick meshing due to no. of nodes and mesh flow
lines.
Previously, all the organizations used
to brick mesh solid parts. So, in case if objective is to compare existing
model with the previous one then it has to be modeled using same type of
element and length for a logical comparison.
