Dam Break sigFpe Error

aow · September 7, 2017, 19:13

Hello CFD-Online Community,

I'm trying to update to OpenFOAM-5.0 from OpenFOAM-2.2.1 and want to re-validate my case setup using data from a dam break experiment performed in a wave flume with a bridge deck to measure the forces and pressures applied to the structure. I'm using the interFoam solver and running this case in parallel using 8 8-core machines in the University of Washington's HPC network, Hyak, which uses Red Hat Linux (kernel version 2.6.32-696.3.2.el6.x86_64). OpenFOAM-5.0 was compiled using gcc 5.1.0 with openmpi 1.10.1. The initial state of this setup was reproduced successfully in OpenFOAM as shown below.

Initial state (domain is truncated in the image)

As far as I can tell, I've updated all of my case files adequately; however, it appears that I'm having issues with the solution blowing up when the wave is just about to impact the bridge deck as shown below.

Blow up state (domain is truncated in the image)

Does anyone here have any clues as to why this may be occurring? I'm wondering if the solution schemes changing from one OpenFOAM version to another is hurting me somehow. I used the interFoam dambreak tutorial setup as an example for how to modify my old case to work with OpenFOAM-5.0, but am not noticing any red flags in the scripts.

I've attached a .zip of the case files prior to being run as well as directly posting the log file, error output, fvSchemes, and fvSolution, which seemed like the most relevant things to post in full here.

Thanks in advance!

The finite volume schemes and solution method scripts are shown below.

fvSchemes

Code:

The relaxation factors (in fvSolution) are too high. Try to use less than 0.5

Thanks for the tip! I completely overlooked the fact that the relaxation factor was set to 1. I'll try it out when I have some time early next week and if all goes well I'll post again to confirm that the issue is resolved.
