How can Fluent Meshing extend WB Meshing?
Workbench Meshing is the proposed meshing solution, Fluent
●
Meshing is a complement. With Workbench Meshing, you have
ease-of-use,, pparametric and ppersistence througghout the meshingg
process. But if the time/quality does not meet client needs for a
specific model, Fluent Meshing could be your back-up solution.
Note that geometry/mesh changes are not parametric with Fluent
●
Meshing, except using advanced scripting
Fluent Meshing has extended capabilities to produce high quality
●
meshes
Fluent Meshing is directly available to all Fluent users without any
