Structured hexahedral mesh in workbench
I have been using ICEM CFD to generate block structured meshes and then using Ansys CFX to setup and run the simulations for quiet some time.
Now I want to automate the process of making a parametric modification in geometry, generating the mesh and running the simulation in CFX.
I have very recently started exploring Ansys workbench. The Design modeler helps to create a parametric geometry.
But I could not find a way to create a structure hexahedral mesh (as in ICEM CFD) in the Mesh cell of the Fluid Flow (CFX) . I could see that it creates a unstructured tetrahedral volume mesh.
How can I create a structured hexahedral mesh in the Mesh cell of this module?
Thanks a lot for your inputs !
First thing here is ICEM is not in workbench platform. So,its not possible for you to work parametrization for your design using ICEM in workbench.
May i know which version u r using?
If you using V13, then ansys meshing is better option, where you can select solver type (CFX/Fluent/Polyflow) for meshing.
Do calibration for your satisfaction.
Personally, I would not recommend using Workbench with ICEM, there is an option to have your model mesh automatically using an ICEM tcl/tk script, but I have not found it very reliable.
You should be able to script your whole process with not too much difficulty. I have used Matlab to generate parametric inputs for geometry, recursively run the simulations for different variables, and then import some quantitive results from an output file. If you do not have access to Matlab, you could script using C, Fortran, shell commands etc etc. I personally prefer Matlab because it is easy to work with, and can be very handy if you are trying to optimise your design based on parameters.
