Description:
After changing the writeInterval while
case is running OF doesnt write to
disk anymore.

Solver/Application:
bubbleFoam

Source file:

Testcase:
axiCase.tar.bz2

Platform:
probably non-specific but I run Gentoo 32

Version:
OpenFOAM 1.5
rebuilt

Notes:
I run the case as it is (attached).
after some time 0.4
I realised that
writeInterval 0.01;

in another terminal i changed
writeInterval 0.1;
and the cases are not written any more.
reverting back to
writeInterval 0.01;
and everything is like it was
(writing every 0.01s)

I run this case twice - the same result.

Thanks in advance

I've had similar problems with the twoPhaseEulerFoam - a close relative to the bubbleFoam - in the 1.4.1 version. So it probably isn't a 1.5 related issue. Probably has more to do with the solver.

This is a known problem that occurs sometimes but not always when the writeInterval is changed. We will work on it when we have sorted some other pressing issues.

Could you try this fix and let us know if it helps? (replace OpenFOAM/db/Time/TimeIO.C with attached version and 'wmake libso OpenFOAM')

TimeIO.C

Thanks for this. It works fine now.
I was not really bothered so much by this bug.
It was more like making OF bulletproof.

Another not bothering bug is when in your
path or case have a space (for some strange
reason) ie

/home/OFuser/All cases/case1

with current implementation, the solver interprets it as two arguments. Again not bothering but worth to think for next release.
Cheers

It would be VERY difficult to support spaces in the "fileName" and "word" types in the OpenFOAM parser and we do not currently have any plans to attempt it. Have you considered using "_" instead of spaces in your file and directory names?
