5 Attachment(s)
Hi ever one. I am trying to run a case where all the files can be found in the following link
:https://www.hpc.ntnu.no/display/hpc/...Postprocessing I followed every single steps as described. However, when I try to run blockMesh I get warnings , I have attached all the warning I get , the first document is the warning I get from running the blockMesh, the second is from setFields and the third is from decompose. After decomposing , I tried to run it in parallel but then I get errors which I have attached to this quote. I have also attached controlDict file where I have the libs and functions added to it. Why I want to run this case? I have to model a case which is very similar to this one. I know how to model it and how to run it successfully but with out adding any thing to the controlDict file.. the only reason I want to model the case is to find out how alpha1 (Volume of Fluid ) decreases with time. Attachment 27015 Attachment 27016 Attachment 27017 Attachment 27018 Attachment 27019 The link, has a graph in it, I have attached the graph to this quote as well. This is want I need to produce , but I cannot without your help. So please someone help me I really need to solve the problem and learn it. I do really appreciate your help a lot. Best regards, Salam |

Hi Salam,
In reference to you posts on this thread: http://www.cfd-online.com/Forums/ope...trol-dict.html - we can gather a full picture of the problem. The main issue is whether swak4Foam is properly installed or not. From what I can see, you're using OpenFOAM 2.2.2. Here are the steps I suggest that you follow:
Now comes the part regarding the aforementioned case, available at the end of this page: https://www.hpc.ntnu.no/display/hpc/...Postprocessing I ran the following commands to download and unpack the package: Code:
cd $FOAM_RUN Code:
cd beerBottle
Code:
./Allclean Best regards, Bruno |

Do you think that I can find someone as good as yourself to teach me how to learn OpenFOAM ? Of course not for free. Best regards Salam |
Hi Salam,
Check the links at http://openfoamwiki.net/index.php/Main_Page - section "3.1 Training". Best regards, Bruno |

Thanks for the reply, I will check the website . About the above case, I could run it successfully , but when I tried to do the graph I got the following message and never got the graph. Can I ask for some help with this please? Code:
salam@salam:~$ cd OpenFOAM/salam-2.2.2/run/beerBottle/ Salam |

In addition, if you run the script "fillLevel.plot": Code:
./fillLevel.plot |

I did the change to the line, and I got a fresh copy of fvScheme manually. When I run allclean it goes through, but when I run allrun I get this : Code:
salam@salam:~/OpenFOAM/salam-2.2.2/run/beerBottle$ ./Allclean Salam |
Hi Salam,
Please follow the instructions from the second link on my signature, for posting code and terminal output. And, please, also edit your previous posts as well, to wrap the outputs into the "[CODE]" markers. As for the error at the beginning of Allrun, that's because Octave is not installed. If you are using Ubuntu, run: Code:
sudo apt-get install octave Bruno |

Thank you for the reply, I will do as you said. I have installed octave, but I still get the following warning: Code:
salam@salam:~$ cd OpenFOAM/salam-2.2.2/run/beerBottle/ Regards, Salam |
Hi Salam,
Check the contents of the files located in the folder "output". They should give a clear idea of what happened. Best regards, Bruno |
Hi Bruno,
Thanks a lot for your valuebale comments. I did run my case. At the final step , where I to run ./Allrun , I get the following error message, do you have any ideas on how to solve this please? Code:
salam@salam:~/OpenFOAM/salam-2.2.2/run/mycase$ paraFoam Salam |
Hi Salam,
Once again, you need to check the contents of the files located in the folder "output", because they can give a better idea as to what went wrong. You should also check the contents of the folder "postProcessing", since the Allrun script is indicating that the aforementioned files were not accessible. Best regards, Bruno |
Hi Bruno,
I am terribly sorry for bothering, but your help means a lot to me. I did check the output folder, and I found error messages there . One of the errors is due to polyMesh , I don't know why there should be any errors. The error is : Code:
/*---------------------------------------------------------------------------*\ Best regards, Salam |
Hi Salam,
You need to check the output files by the order they are created, according to the script file Allrun. The very first output file is the one to check, namely "output/1-blockMesh.log". If it shows you an error message, then that's the one that needs to be fixed first. Best regards, Bruno |

Thank you so much for your help. I would never be able to solve this without your help. I think the problem is fixed now, and I get the graphs . Thank you again. Best regards, Salam |
Hi Bruno,
I hope you are doing well. I am sorry for taking your time again. I did run my case, and in the output folder, I always get the following warning in the interFoam.log file, but the simulation still goes through: can you help me to fix it please? . Code:
'outputInterval' not found in totalLiquid Why when I go for finer mesh , the volume of fluid (Alpha1) runs slower , I mean lesser fluid leaves the domain with finer mesh (even though I don't change the EndTime), can you please kindly explain this to me? I would be grateful for your help. I know you have already helped me more than enough , I really appreciate it. Best regards, Salam |
