Ansys Meshing vs Ansys ICEM CFD
 

Hi,

In your experience which one is the better package to use for meshing and why?

I can't make my mind up as to stay with Ansys Meshing or learn how to use Ansys ICEM CFD.


I have read Ansys ICEM CFD is a very powerful mesher.


Thanks

Ansys meshing is more simple. So, for basic geometry Ansys mesh could save time. But if you want more tools and more control of your mesh ICEM CFD is better.

If you want a structured mesh, ICEM.

If you want an unstructured mesh, T-Grid; but I will compromise and say that you can use Ansys Meshing.

my experience: ICEM is a huge pain in your butt
very few tutorials
everything too complex and always driving you crazy

ICEM Hexa is really tough and stressfull. especially with complex geometries. For normal geometries and applications, it's very powerfull.

You need to learn basic blocking strategies for the most common applications. Once, you've the skills, it's as I said very powerfull.

For huge models (up to 20 million cells) Spider is my first choice. Gridgen Pro is also very good and much less complicated as ICEM Hexa.

For turbomachinery, Turbogrid is the best software in my opinion. I've meshed a turbine wheel with ICEM Hexa and the mesh wasn't nowhere near as good as the Turbogrid mesh.

Personally, I am an ICEM CFD user.

Since Ansys bought out the ICEM CFD I ( and few others I have asked) have tried Ansys mesher a number of times but we haven't discovered reasons to move to Ansys mesher yet.

What I heard is that Ansys will gradually improve Ansys mesher to have all the functionality of ICEM CFD but who know when that is going to be finished.

Meanwhile is there some functions ICEM has but not Ansys mesher and you would like to use them? If not is investment in your time to learn a new software worthwhile for other reasons? These are the questions you should be asking.
