dieselFoam tutorial - OpenFOAM-1.6-ext
 
Hi,

I tried to run the tutorial aachen bomb with 1.6-ext but it crashes after a while with the error janaf out of temperature range.
That s very strange, since I ve run that tut with other OF versions without problems. Can anyone check if you get the same error? Maybe my OpenFOAM-1.6-ext is not properly compiled.

Regards
Peter

Have you made any changes to the tutorial?

If not can you tell what exactly are you doing to run that tut?

Are you running the tut provided with OF-1.6.x only?

I am not sure why this may be happening but your answers to above questions might make it possible to help you.

I am using OF-1.6-ext and not 1.6-x. I am using the tut provided by 1.6-ext. This is the error which I get after a while. In the beginning it runs but than it crashes. Furthermore, a case which runs with OF 1.5-dev exhibit the same problem.

Hi,

That's pretty strange. Usually tutorials run without a hitch. You may try to re-install your OF. Have you tried running other tutorials?

If you find a solution to this problem then do post it here.

Indeed it s strange. Other tutorials run without a problem. I checked the source code of the dieselFoam solver. It is modified to the version of 1.5-dev. Maybe a bug?

Can someone of u check if the tut aachenbomb (dieselFoam) provided by 1.6-ext with OF-1.6-ext runs to the end?
I ve tested it on two different systems.

Did you fix the problem?
Maybe you did change some settings in the injectorproperties?

Peter_600 January 10, 2011 12:31
No. I didn t :(
Does it work out for you?

Hi

I am uploading the aachenbomb tutorial from OF-1.7.1 Try running it with OF-1.6-ext.

If you succeed then find out the differences and post them here.

It doesn t tun neither. The only difference is that in sprayProperties this is adjusted
sprayIteration
{
sprayIterate 1;
sprayRelaxFactor 1;
minimumParcelMass 1e-14;
}

but this was already implemented in OF-1.5-dev.
The tut ends with this error

I have no idea what is wrong.

I have the same problem, the tutorial case doesn't work.

I tried to used some personal cases from 1.7.x, which were okay but they don't work on 1.6-ext too, I get the same error. :(
