Dear friends,
I am running a lagrangian simulation using sprayFoam solver and whenever I am trying to run it, I get an error as attached below. Can someone please tell me how to solve this error? Last edited by -mAx-; September 22, 2022 at 03:19. |

Hello,
Maybe you sould share your kinematicProperties file |

Thank you very much Lucie for your reply.
here below, I am attaching the google drive link of my whole sprayCloudProperties file https://drive.google.com/file/d/1Otl...ew?usp=sharing I have also attached a pic of the submodels part of my sprayCloudProperties file in case you face any problem with the link Last edited by -mAx-; September 22, 2022 at 03:19. |

I don't see the problem... Did you compare your fvSchemes and fvSolution with the only s sprayFoam tutorial?

Yes. I copied the fvSchemes and fvSolutions files of this simulation from the tutorial case.

Hi,
log of a standard tutorial (aachenBomb) is something like this; Code:
No finite volume options present Courant Number mean: 0 max: 0 Starting time loop compressibleCourantNo.H file calculate Courant number and involve the division (/) by rho. If rho is zero at anywhere, it will give you the error message you got. rho will be obtained by thermophysical properties model you used. Incorrect p and T may cause unrealistic rho. My recommendation is to check thermophysical model and settings, boundary conditions, and initial conditions. |

Thank you very much Shinji for your reply.
I have another question. If I want to give an atmospheric boundary condition at the outlet of my domain, what value should I give in my p file? Should I give a value of 0 Pa(i.e. the gauge pressure) or should I give 1e5 Pa(i.e. the absolute value)? |
