Best Mesh Generation Software
Ennova is a commercial pre- post- processor that can import, clean and repair CAD and generate tet + prism meshes or polyhedral meshes with boundary layers. Can also do block structured meshes like ICEM HEXA. Developed by the same team that created ICEM CFD. Free for students ! Reasonable cost for commercial applications. Visit www.ennova-cfd.com. Thanks -Mike

Best Mesh Generation Software
Hello i'm looking for the best tools to perform the following task:
I have 3D-Parts designed with CATIA V5, which are connected to eachother for example by welding points. These 3D Assemblies shall be converted to a 2D-Mesh (triangular), which represents the surface of the assembly and the electrical proberties (including the connections). The Data shall be send as a NASTRAN-File. This File will be processed with ANSYS HFSS and/or Altaire Feko, to simulate Radioantennas attached to the assembly.
Which Mesher will be the best, if i want as much automatisation as possible?Posted December 13, 2016 at 08:30 by Virgil -
Best Mesh Generation Software
Thanks for replying to my post Far and aerospace84...The problem that i'm having in my case is that, when I start solution in Fluent initially residuals keep falling but after a few thousand iteration my residuals keep oscillating in a straight line...it looks like its stuck forever...I have tried solving it with different viscous models, also lowered under relaxation factors and tried to change solution methods...but its not helping...I thought i have bad mesh thats why i wanted to improve mesh with some other meshing software...but when i checked my mesh metrics i.e. skewness, aspect ratio etc. looks good in ansys meshing...so if my mesh is already good enough then whats stopping my case from converging?
can anyone please help me with this?Posted June 12, 2016 at 15:16 by diwakar -

then if you have bad cell clean the geometry, put some virtual surface and set properly the mesh sizes..it works in the 99.999% of casesPosted June 10, 2016 at 08:20 by aerospace84 -

yep i agree but if you want to run faster with an acceptable/good mesh ansys meshing is the tool. For other academic purpose that need only hexa i suggest ICEM. if you need polyhedral then you can convert your tetra mesh easily in fluent clicking a button.Posted June 10, 2016 at 08:18 by aerospace84 -

Hi, i wanna perform a Conjugate heat transfer analysis... basically its a 3D gas turbine blade film cooling simulation in ANSYS Fluent...U can see my geometry in pics attached...the blade is twisted & tapered and has internal cooling geometry and hole rows on it...its quite complex geometry

hi, I will be performing hydrodynamic simulations to assess turbulence in porous obstructions and I will use OpenFOAM as the platform to perform the simulations. What is the best tool (software) to generate the computational grid for OpenFOAM for complicated flow domains? it can be commercial or open source.Posted March 3, 2015 at 08:28 by saharhad -

It is mentioned there that CFX is already a polyhedra solver by default, but it does not accept poly meshes...
Fluent can easily handle poly meshes etc...
There is some advantage of poly meshes in case of high swirl, which CFX automatically gives you, as it is already solving equations on poly meshes...
But you can not avoid bad quality in narrow gap with the help of poly...
Poly is inverse of tetra...
There is no standard method to measure the quality of poly mesh...
So in short "poly will not be the magic solution to CFD problems"Posted July 27, 2014 at 15:50 by Far -

I had a study about that. using polyhedral mesh result in faster solution in some casesPosted July 27, 2014 at 14:54 by aroma -

Never did the comparison between fluent and star ccm+. But i believe there is no need for polyhedra meshes...Posted July 27, 2014 at 07:29 by Far -

What about star-CCM+? I found that very easy and efficient in polyhedral mesh generation. Have you made any comparison between Fluent poly and Star-CCM+ polyhedral mesh?

I am new to icem. Now I need to mesh a radial compressor with splitter blades. Could you give me some advice? I will be very appreciated if there is some tutorials related to mesh generation of radial compressor by using icemPosted April 30, 2014 at 03:03 by dowlee -
CFX or Fluent for Turbo machinery ?
Hello Guys,
I am working on project Flow field analysis through rotor 37 ANSYS CFX. Could anyone please let me know about which turbulence model is better to get results and why ?
I really appreciate .
Thanks

CFX or Fluent for Turbo machinery ?
Quote:Regarding the comments 2,3 and 4. These problems in Fluent seems to overcome with the new solver technology such as solution steering, pseudo time control, hybrid initialization and better convergence in version 13.
Now one can get the same solution in one order less iterations (10000--->> 1000 or even less) with few orders more convergence (instead of 1e-02 to 1e-04).
Even with the linking to design modeler and ansys meshing (ICEM to be included in workbench in release 14.5) through the ANSYS workbench one can easily perform and update the parametric analysis in Fluent.
Still I feel that the CFX is better than Fluent in turbo machinery (This can be seen from the latest development in turbo machinery modules in CFX 13.) and Fluent in better in external aerodynamics, two phase modeling, combustion and other (all) type of problems.
CFX has also better option for two-way FSI.
Embedded LES is another strong feature of Fluent but What I cannot understand why CFX has still not included the embedded rotating reference module which is available in Fluent V 13.0.Posted December 9, 2013 at 05:52 by Anna Tian -
Accelerating CFD Solutions (Fluent)
Hi Far,
Since speeding up solutions has to be done carefully, and since ANSYS published some interesting stuff on the topic of turbulence, here's the link to one of their recent blog posts:

Hello Far,
I am using ICEM, but have recently heard about about Gmsh.
"Gmsh is a 3D finite element grid generator with a build-in CAD engine and post-processor."
Easy to use according to the people who have used it. I just heard it today so thought it might be useful information for others here. Although i haven't used it.
One can get the software for free from website below:
