Hi,
The Brook's ports is great! The application "icoFoam" can run smoothly.
but when I run dieselFoam, the problem is as following:

What's wrong?

thanx

I have just checked it - works

I get the same error on my Cyg
 

I get the same error on my Cygwin installation. Hrv, were you testing on Cygwin, or on another OS?

The problem, I believe, is that in the aachenbomb/constant/thermophysicalProperties file, the CHEMKINThermoFile is specified as "$FOAM_ROOT/$FOAM_CASE/chemkin/therm.dat", and Cygwin does not appear to be handling the $FOAM_ROOT and $FOAM_CASE correctly.

Changing the two relevant lines in thermophysicalProperties to:

CHEMKINFile "$FOAM_TUTORIALS/dieselFoam/aachenBomb/chemkin/chem.inp";
CHEMKINThermoFile "$FOAM_TUTORIALS/dieselFoam/aachenBomb/chemkin/therm.dat";

seems to make things work correctly, and I then get the same results Hrv does.

Thus, I'm guessing that $FOAM_ROOT and $FOAM_CASE aren't getting set properly; Hrv, if you have any suggestions for how to track down where that should be happening and why it isn't, I'd appreciate it.

In the meantime, not using $FOAM_ROOT and $FOAM_CASE to specify the filename should work as a workaround, though it's a bit of a hassle if you copy the file into a new case or such.

Update: It looks like the code
 

Update: It looks like the code that sets the $FOAM_ROOT and $FOAM_CASE environment variables is in src/OpenFOAM/global/arglist/arglist.C. I'm guessing the problem is some sort of Cygwin weirdness with what scope they get set in, but it could be something in the port. Unfortunately I don't have much time to work on this right now.

The trick of Brooks can make it run, but foamToVTK didn't work for the case.
