I was trying to run the channel flow case with the dynamic one eq eddy viscosity LES model. I am using the latest Openfoam 1.5 version on Ubuntu Linux, which i pulled from the GIT repository. I got the following error message.

I have just run dynOneEqEddy model on the channelOodles tutorial case without incident:

I am unable to reproduce the failure you are getting. Could you try running in valgrind?

[harishg]

I ran it with valgrind upto T=0.4 with dt=0.2 and it ran.I did not have problems with the other LES models that I tried ( smagorinksy, oneeqeqqy, dynsmagorinsky, locdynsmagorinsky) before. This is the log of the run

[zeliboba]

I confirm the bug, I have very similar error, the case is different though. in my case it occurs only when run in parallel, i.e. with -parallel option, in serial execution it seems to work.

[harishg]

I did a fresh install of OpenFOAM on another machine and the dynamic one equation model did not produce any errors for a serial execution. I think that there was some problem with how I cleaned the openfoam 1.5 installation before installing the openfoam 1.5.x from the git repository.

[zeliboba]

serial execution works on my install also, try parallel.
