hi,
I don't know how to read the meshes by Fortran. I need to program, but I don't know the meshing rule of ICEM, especially the multiple grid. what can I do now? |

Hi
There are different ways to write out the mesh information in ICEM. Me personally I like the FluentV6 output, because it is in ASCII. So you can read it for small test cases and compare it with the information the code reads in and see if your routine for the read in is right. The structure of the FluentV6 files is also easy to understand and straight forward. You won't need more than a day or two to write the routine. I have a commented example file somewhere on my home-PC. I'll try to find it, when I'm home. Like I said before, there are heaps of other ways to write out the generated file from ICEM. I suggest just try a few common ones and choose the one you understood the best. |

Just to add with the previous post by Marcus, you can just export icem mesh in cgns format (w/o reading in fluent) & read it in fortran provided you have already installed cgns library.

with C++, cgns is more easy-to-use ..*teardrops from a "vintage" fortran admirer*

Hey,
Hope you are doing well. I have a very quick question. Actually I drew a rectangular geometry with two zones (interior1 and interior 2) in ICEM and mesh it and could bring it to the Fluent including all of the boundary conditions but I cannot bring the surfaces ( interior one and two) to the fluent. The fluent does not show me the surfaces. Would you please give me a hint. Thanks |

I might be facing similar problems with exporting from ICEM for multiblock grid in a CGNS format. I can choose to either output volumes or surfaces and there is a pop-up message where the user is required to choose. This appears when you right click on pre-mesh and choose convert to structured multiblock mesh.
There should be a way to combine them and export both, otherwise I do not see how we can assign boundary conditions properly. Look forward to some interesting comments and suggestions on here. Thank you.

Hi,
I'm also working on reading the FluentV6 output from ICEM using FORTRAN. Could you please give me your sample commented example file to help me read it in FORTRAN? my email address: yaomin_yaomin@163.com Quote:
