Hi!
I'm trying to conduct a parallel simulation using OpenFoam 1.7, and interFoam. When I use value in blockMeshDict convertToMeters = 1 all is good, but when I use 100 (to work in real scale) there is a strange error with that I had never encounted. Here is the log:

Maybe you have encounted this error message?
I don't understand what is wrong

[davidmd]

Surely no one knows what's going on?

[alexeym]

Hi,

If you just want to know "what's going on" - "your solution diverges".

But I guess your next question will be "why it diverges?". At this point you'll need to find a person who a) still uses OF 1.7.x, b) has desire to guess your geometry, mesh quality, initial and boundary conditions, c) and has desire to answer a question. I won't be easy to meet such person.
