[Commercial meshers] Problem with fluentMeshToFoam

whitecat · August 28, 2008, 05:32

While converting a Fluent mesh created by ICEM CFD, I got the folling error message

Exec : fluentMeshToFoam fluent -case fluent
Date : Aug 28 2008
Time : 09:18:57
Host : flux4
PID : 4838
Case : ./fluent
nProcs : 1

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create time

input in flex scanner failed

What is wrong?

Can anyone help me? Thanks.

Is the Fluent file ascii? Compare e.g. with icoFoam/elbow/elbow.msh in the tutorials.

The Fluent file is in ASCII format and created by ICEM CFD Version 11.

According to ICEM CFD this Fluent file has the Fluent V6 format. I don't know whether openFoam 1.5 supports Fluent V6 file.

So what is different when you load them in an editor? Is the structure the same? Can you post a small sample file?

Hi N.Wei!

This is just a guess: was the ASCII-file created on a Windoze-machine and moved to Linux/Unix/etc? In that case try dos2unix or a similar utility on it before trying to convert it (see discusions about Windows-Newline is two times ***x-newline elsewhere on the board and if I remember it correctly fluentMeshToFoam cares about that difference)
