Hi,
Unsuccessfully, I’m trying to make FLUENT to accept my MESH file (in ANSYS WorkBench), and I’m quite stuck with it… I’m trying to simulate the 2D flow over the shape that I attached to this thread. Somehow, no matter which shape of domain I’m using, when trying to do the SETUP, and updating the MESH, I get this message over and over again- “The mesh file exporter failed during translation…“ I tried splitting the domain into different areas and Map it, I tried Sizing controls… But still, nothing… If anyone have a good idea - I’ll be grateful, Thanks |

Well, Basicly I’m meshing in the Mesh software of ANSYS 13, and then open it with FLUENT directly from WorkBench.
However, I can export the MESH file as msh, meshdat and also poly,cgns,prj and tgf. |

Yea, it is 2D on X-Y plane

OK, so here are two snapshots, which I hope can be relevant...
(Even though I couldn't find any useful information from this... ) The first is from WorkBench, and the second is from the mesh program of one of the attempts |

Hello OfirLaor and Far
I am sorry to hijack this topic, but I have exactly the same problem with ANSYS Workbench 13.0 and whatever the simplest geometry and mesh I try to make, I have the same error message : "The mesh file exporter failed during translation..." Actually, I want to mesh a simple 2D square... The difference with OfirLaor's case is that I cannot export my mesh in ASCII MSH file (I obtain the same error message); I can export in binary formats however. Do you have any solution or advice for this problem? What is wrong with this? Thank you a lot for your help |

So, what did you do? Did you use another mesher software?

Well, this specific problem was the first out of 370 models I tested, in order to get some results, which I can analyse and compare between... So actualy, I didn't need a high resolution of accuracy. Therefore I solved the models with SolidWorks Flow simulation. However, if you're looking for a very accurate solution, I reccomend you to stay with Ansys... Please let me know if you find somthing... thanks

The fact is I build meshes with Workbench long ago (one year...). But now, I am completelly unable to create any new one, even the simpliest square. That is very confusing...
If I have any trick, I will tell you. |

Well, I have some news for you OfirLaor !
According to my school IT supervisor, version 13.1p1 of WorkBench isn't supported by Ubuntu yet, but it is OK under RHE 5 or SLES 10. Since I am working under Ubuntu, this should be the reason of the error message. Version 14 (and 13.0) should be (is) OK with Ubuntu. I will have a try with it as soon as my IT supervisor installs it. Hope it helps. |

Hi,
For Fluent 2D analysis through workbench, we need to change the simulation type to "2D" before opening DM & Ansys mesher in workbench schematic. This will be available in properties panel. To get the properties, right click the fluent flow and select properties Otherwise, Fluent will not accept the mesh. This might be the reason.

Well, jsm, actually I have already set this parameter on 2D.
I add I have tried a 3D cube and the result was exactly the same. The OS incompatibility is reported on ANSYS' technical website (I don't have the source). |

Yes, version 13.0 works quite good on Ubuntu Linux.

I have additionnaly some news for you! WorkBench on Linux needs a default Bash Shell (executables refers to /bin/bash). You have to set it up if your default shell is Sh or Tcsh (like in my school).

Hi Nerasta,
I got good news! Apparently, my problem was easy… I used Workbench and there I had “Mesh” system (box) which I have created the geometry and mesh, and I linked the mesh to other “Fluent” system to the setup. So that was somehow wrong to do… I did the same with one system of “FluidFlow (Fluent)”, and then I had no Error…. Hope this might help, Have a nice day! |
