Hi all,

I have recently come across a body-fitted meshing technique in the literature (van Hoof and Blocken, 2010) that I would like to adopt in my simulations. The technique is called the "surface-grid extrusion technique". Basically, it generates high quality hex grids for "very complex building and urban geometries", albeit labor and time intensive.

I have compiled the details of this method in the PDF link:

My questions here is regarding the meshing tool. I am not sure which to use.

Studies adopting this technique have mentioned using GAMBIT. So far, I've been using ANSYS meshing for my simulations, so ideally I prefer to stick with ANSYS tools. However, I understand it may be a far stretch to expect this level of user control from ANSYS meshing.

The other option is ICEM, which I have not used in any extensive capacity. I suspect this technique is possible in ICEM, although I would appreciate if any ICEM users can confirm this.
Also, any specific pointers on how to adopt this method in ICEM are greatly appreciated.

Thanks.
