Hello Foam-Experts!
I'm really new to OpenFoam and the programming in it and so I'm not experienced with it. But for my studies I got the following task: I have to simulate a solid cylinder hanging in air. The cylinder radiates heat and convection is on hand. So I use "chtMultiRegionFoam" with the command Code:
mpirun -np 3 chtMultiRegionFoam -parallel Then I realized, that the error-messages for both cases are the same. This error-message appears after the thermophysical properties for region air were read and added and ends up like: Code:
mpirun noticed that process rank 2 with PID 477 on node boot2docker exited on signal 8 <Floating point exception> Because an error-message like that appears for my case as well as for the model-programm, I guess the error is not my fault. So I would like to ask you all, what the problem actually is. By the way I use the windows-version of OpenFoam. I really please you to help me and also if you need some more information about my problem, please answer me as soon as possible. Thanks in advance Raffael |

I really need to be helped with this problem. I don't know what the error message means and what to do about that. It is really important for me.
I'm not experienced with OpenFOAM and maybe I did something wrong. But until now I found nothing... I really please you to help me! Thanks in advance Raffael |

Hi,
The error message that you have is a Floating Point Exception. The most likely culprit for this is a division by zero somewhere. Look through the different boundary condition files and see if there is something that shouldn't be zero is zero. What does the log of your run say apart from the mpirun run abort? Cheers, Antimony |

Hello Antimony,
At first I have to say, that I'm very thankful for you're reply! A division by zero? That's a good point to look for, thanks for that. I'll post about the results of my upcoming search later. The whole error-message looks like this: Code:

Hi,
You can get the entire output to a log file by adding "2>&1" at the end of the function call. Since it seems to stop after loading your thermophysical properties, is your temperature 0 at any point? Do take care that the units of temperature are in K... Cheers, Antimony |

Hello Antimony,
I checked for zeros in all initial fields, espacially for the temperatures. Thereby I realized, that after every execution of chtMultiRegionFoam all temperatures are set on default (293K), although I've set them before on whole other values. I corrected it, but still this error-message appears: Code:

From the error it appears that you are using a "calculated" boundary condition in a boundary with the type empty.
If you need to use the calculated boundary, check if that boundary is defined as patch or wall on the "boundary" file (constant/<region>/polyMesh/boundary). I hope it helps you! |

Hello Joćo!
I thank you so much for your advice. This problem is solved, but now I'm standing in front of the next problem.... like I said, I'm very new to this and know almost nothing about OpenFOAM. Now appears the following error: Code:

Since the fvSolution file is the same for all the processors, the solvers reads it from the system folder.
In this fvSolution file you need to have the PIMPLE keywords with the inputs you need/want. Did you construct the fvSolution yourself or did you copied it from another location? It appears that you copied it from a tutorial of a steady-state solver. As you are using chtMultiRegionFoam look into the tutorials for this solver. For example: $FOAM_TUTORIALS/heatTransfer/chtMultiRegionFoam/multiRegionHeater Check the fvSolution of this tutorial and update your own with the required keywords. |

No problem
Let's see, from what i understand you are using a boundary condition named "calculated" in the U field (0/<region>/U). And the error says that you cannot use such type. I'm not into your project so i can't give you a more detailed advice on what boundary type you should use. However, fixedValue or zeroGradient is normally used on the U field. |

Hello Joćo and all the other Foamers out there,
again thanks for your help! I changed the boundary conditions for "U" for both regions and by the way I realized, that "k" and "epsilon" are both zero when "U" is zero (I have no moving fluid in my system). So I changed them too. But like always it doesn't work... This time the message looks like this: Code:

The error is the same so you already know how to solve it, if needed
Regarding the h field, that's weird.. Do you have any file named "h" in your 0/ or 0/<region>/ folder? The solver does not require such field although i recall having some problems for having "not needed" fields in the 0/ folder. Anyway, can you check that? |

Hello Joćo,
I know that the error-message is the same like before, but the problem is, that I have no h-file, neither in the 0-folder nor in the 0/<region>/ folder. I also checked for the processor-folders and there isn't h as well. I just have these: cellToRegion epsilon k p p_rgh T U Why does OpenFOAM ask for "h"? Like you said... the solver doesn't need h. Could it be, that the problem is in one of the other files? Maybe in p_rgh? By the way, can I ask what the difference between p and p_rgh is? p_rgh is the only file with an h in it, so maybe this is meant. Thanks in advance Raffael |

Hi,
"h" here should refer to enthalpy(?), basically it is associated with the temperature field, if my understanding is correct. Check your T boundary conditions... For your other question: http://www.cfd-online.com/Forums/ope...tml#post276743 Cheers, Antimony |

Hello Antimony and Joćo,
Thank you Antimony for the helpful advice. I checked my T-files and after I used chtMultiRegionFoam OpenFOAM complained about p_rgh with the same issue. So I checked all the files again and now a new error appeared. I looked through other threads, but there they didn't come to a solution to my problem now. The error-message looks like this: Code:

First question, are you using a time-step of 300?
If so, you need to lower that value, otherwise you won't be able to obtain any results. Anyway, if changing that the same problem appears: Code:
Min/max T:-2.85e+10 3.32e+09 You can also try another schemes (fvSchemes). Are you using first or second order schemes? The mesh could be also the reason of your problem/divergence. What you can do is write the results on the previous time-step and check where are located the cells with such T values. Is it clear? |

Hello Joćo,
thank you for your help! But this time I realized, what a noob I am. To your first questeion: Yes, I wanted to create a kind of fast motion. But I followed your advice and took the tenth part of it - so it's 30 now. What do you mean by your code? I tried to use it after the first error but OpenFOAM didn't know what to do with that. Can you tell me more about the code and the purpose behind that? Your advice to play with the relaxation factors and tolerances I followed as good as I can. The matter is... I don't know how the change of a relaxation factor affects on the simulation or the output. What I also didn't understand was, what do you mean by first or second order scheme? Another scheme? I really don't know anything about the fvscheme-file... I just copied it from the tutorial "multiRegionHeater". Quote:

I advise you to study how simulations work which will help you a lot on how to stabilise your case. Check this link regarding the first/second order schemes. The mesh could obviously be a problem, it affects the way that the equations are solved. Again, you should look for more information regarding this subject.
To be honest I have no idea about the new error you have. Don't know if any user of the forum have experience with this. To write the results, you need to adjust the writeInterval variable (system/controlDict) to match with the time-step when the error occurs. Anyway the time-step still looks too high for me, however I don't know if it's part of your setup. Do you have any information about the error you have at the moment? |
