I've been having a lot of trouble tracing the source of this error. I know it happens in the thermoI.H file, but I can't trace what is calling that, or figure out any reason why this is happening.
The case i am running is a simple wedge (meshed with snappy hex mesh) inside a blockmesh region using rhoCentral foam. any help would be really appreciated this is the error log file Code:

Also, I changed the boundary conditions to supersonicFreestream and waveTransmissive in hopes that that would help, but i am getting the same problem.
I have my entire post-run case directory on dropbox, with the error located in the log.rho file https://www.dropbox.com/sh/7fvzzazmx...liXvZj0ga?dl=0 Does anyone have any ideas what the problem is? |

Hi,
Have you solved this issue? I'm facing a similar error. I've been working on this error for more than a week but could not solve this yet. Please share if you did. In my observation after trying a lot of things is that they are may be a unit problem of the initial and boundary conditions and thermophysical properties. The tutorial cases use the normalized parameters and as soon as I change them to S.I. units like here it causes this error. |
