| Summary | 0003815: fluent3DMeshToFoam not able to read mesh from R2021 | ||||
| Description | Hi, I've previously used fluent3DMeshToFoam to convert Fluent meshes to Foam and I recently upgraded to Fluent R2021 R2. I created a mesh and got the following error due to square brackets in the .msh ASCII file. /*---------------------------------------------------------------------------*\ ========= | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox \\ / O peration | Website: https://openfoam.org \\ / A nd | Version: dev \\/ M anipulation | \*---------------------------------------------------------------------------*/ Build : dev-69858a80ec41 Exec : fluent3DMeshToFoam fluent3DmeshToFoam_bug.msh Date : Mar 08 2022 Time : 14:31:14 Host : "DKAALT0912" PID : 7777 I/O : uncollated Case : /mnt/c/Users/dkaakbea/OpenFOAM/flocculatorDesign/basecase nProcs : 1 sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster (fileModificationSkew 10) allowSystemOperations : Allowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Reading header: "ANSYS(R) TGLib(TM) 3D, revision 18.1.0" Reading header: "ANSYS(R) TGLib(TM) 3D, revision 18.1.0" Dimension of grid: 3 Number of points: 8263 Number of faces: 12816 Number of cells: 2617 PointGroup: 64 start: 1274 end: 8262.

We have no access to Fluent and so no way to maintain the converter. Can you supply a patch which ensures the converter works with the current AND previous Fluent releases? I tested the .msh file you attached but it converted fine and does not contain any square brackets. |
|
|
I'll look into it. It might take a while, as I haven't got so much time at the moment. I don't know if you can put it "on hold" or something. If anyone else encounters this from Google search, they can simply remove the brackets from the .msh-file until a patch is made. |

I couldn't find any square brackets in the .msh file you sent and it converts fine. |

I accidentally attached the file where the brackets had already been removed. This is the right one. fluent3DmeshToFoam_bug-2.msh (911,624 bytes) |
|
|
I have played around with the text parsing and the attached version parses your case but I don't have many .msh files to test it on to make sure it is backward compatible. Could you test it before I commit it to OpenFOAM-dev? fluent3DMeshToFoam.L (43,055 bytes) |
|
|
Ah, that was quick! I have tested the updated mesh converter on .msh files generated by Fluent 2019 R3, Fluent 2020 R1 and Fluent 2021 R2. I, unfortunately, don't have licenses for previous versions. The updated converter works for all meshes tested. |
