Hi there everybody,
I'm just trying to get familiar with Elmer and to do so, I've just started to get through the tutorials.
However, when I'm just doing it the same way as described in the tutorial, ElmerSolver is crashing down with no explicitly offered message.
I guess its the warning from the SolverLog "Model Input: Unlisted keyword: [flow solution name] in section: [equation 1]"
I saved the Solverlog, the case.sif-File as well as a Picture of my Model (even if I can't imagine this helps, but I thought it wouldn't do no harm neither).
Does anyone of you know what to do in some other way to get it working?
Thanks a lot!
Daniel

Re: Problem with Tutorial 1
Hi,
one possible reason for the crash is that you have specified convection in
your model with no accessible flow field, e.g you should either switch of the
convection or add N-S solver or some such to your simulation setup.
ElmerSolver should not crash so easily on erratic input, i guess, but it
would take some effort to make it so. I'll have a look what i can do for
this specific case...

Oh,
that's it... shame on me... As I'm new to elmer but not new to simulations in general... I should have known myself
Thank you very much!

HI Daniel,
these small mistakes are unavoidable, as we are only humans
Anyway I added a check for this case to HeatSolve.src, and commited it to SVN trunk/.
In future ElmerSolver shouldn't crash, but give (a lot) of warnings 'bout missing
advection field. We could supress the warning also, i guess, if this is inconvenient....

HI,
actually the mistake here might not have been yours at all, but the trouble with the
Convection keyword Adam has been going on. Now this "Convection=Computed"
setting in the sif-file might have been result of the default value of this setting in
the xml file for the free surface solver? If you had that loaded ?
