OpenFOAM killing itself before even starting solution

Jay22kar · May 6, 2021, 03:11

Hello foamers,

Recently I considered using AWS for one of my simulations.
I zipped my case directory, copied from my PC to the remote PC, and unzipped it.
As soon as I start the simulation, it starts reading U file & KILLS itself.

The case runs normally in my PC but KILLS itself on the AWS. Please have a look at the screenshot.

The only difference is - my OpenFOAM version is 2006(.com version) & the remote AWS PC contains OpenFOAM V8(.org version)..

PS - Even decomposePar wasn't working before. I copied decomposeParDict file from V8 motorbike tutorial to one of the case & then decomposePar worked!

Has anyone faced such issues? Any solutions?
Thanks

Hi Jason,

I would suggest to install OpenFOAM-8 on your PC and try to run your case locally.

You will often -not to say always- have problems and things to adjust when switching from one version to another.

I don't know what is going wrong for you, but for sure I would start by checking if my case is running on OpenFOAM-8 before trying to run it on AWS.

Let us know how it goes!
Yann
