Greetings Almir,
At the risk of sending you off in the wrong direction, you can try this answer: My program stops with an output that starts with #0 Foam::error:: PrintStack(Foam::Ostream&) But in an attempt to send you in the right direction:
Best regards, Bruno

Hi Foamers,
I am running twoPhaseEulerFoam and i have increased the mesh size 6000(which was in tutorial bed2) to 24000 and I am getting following error. I tried for 12000 again same.in blockMeshDict it was (30 200 1) first I have changed it to (30 400 1) then (60 400 2) an so on.Another problem is that I have to change the file 0/alpha everytime.is there any other practical solution for that?

Hello Bruno and everyone else,
Allow that I follow up on this thread for I am experience similar issues as those for which the thread was initiated. My log file is as follows: PHP Code:
Could you please have a look at this issue. Thanks in advance. |

Look at the courant number: it's increasing a lot. I think you should reduce the `maxCo' value in the system/controlDict file.
The solution will be slower, but I think it'll works, |

Dear Bruno, Dear All,
thanks for the links that you added. I think they are very useful. Also, I do have a problem with buoyantPimpleFoam. I am trying to impose either temerature or velocity in some cells. I did the same with buoyanSimpleFoam, but I have problems with the steady state. Could you check the folder I modified, please? I am attaching the latest version of my solver, here. Thanks a lot, Samuele |

I did some dummy test cases: 1) a square box that rotates with the AMI; structured mesh 2) same thing with unstructured mesh. Both these cases don't seem to give any error. 3) I did my learning case with unstructured mesh; it consists on two cylindrical rotors (Darrieus). But here I run into trouble with the problem described above. Attached are some pictures to see how the meshes look like. For the latter case, you can see the velocity field is messing in the outer domain where no rotation is happening. Another question I had is how to export hybrid mesh from pointwise to openfoam? By hybrid I mean unstructured in x-y place and we extrude in the z-direction which will then be structured. I tried that but only the structured boundary faces are exported not the unstructured ones. Thank you for your and my best regards. |

Hi ebah6,
Mmm... I'm not an expert on this subject, but this is what I can see that might be the source of the problems:
The other theory is that the thickness of the paddles is having a very big effect on the development of vortexes... and if these are not properly solved, it's only natural that some seriously crazy "fluid pressure shocks" (not a very technical term) will occur. Another issue might be the speed at which the rotor is running. Proper field initialization might be required to induce the solver to start with good starting values; otherwise, you probably will have to simulate starting with the rotation speed at 0 RPM. I'm not very familiar with these solvers, but my guess is that if you only want to have an "averaging" result, then one of the LTS solvers might come in handy... although you would have to create one that would LTS with AMI... Best regards, Bruno

Hello,
Yes Bruno, some of the possible issues are as you mentioned; thanks for your insight. In particular, as the body becomes thinner, I run into problems. However, I am only encountering problems when using a turbulence model: the laminar case runs fine. For the cases with a turbulent flow, I refined the mesh again and again but it still crashes with a skyrocketing Courant Number. My pressing issue is that I need to deal with thin bodies, so I need to a work-around. Also, you suggested the STL snappyHexMesh. I did that in a recent past but the sliding interfaces show step like shape dispite the refinement. Thanks for your help. |

Hi ebah6,
Mmm, if it's not the mesh, then you've got to start tuning the "fvSchemes" file and possibly the "fvSolution" one as well. Unfortunately I don't know much how to configure them properly for each scenario, so I suggest that you check all of the relevant tutorials in OpenFOAM, as well as the User Guide. Good luck! Bruno

Good Afternoon, Everyone!
I come to this place with a similar issue, and upon reading the above comments and filtering through the User Guide for more information about initial conditions for k-epsilon and about the Courant number, I'm still having a heck of a time performing a run. Let me explain the situation to you (I can't post the 0/ files for various reasons): A 7m long blunt object is situated in a 10m/s wind-tunnel, with the floor of the tunnel moving with it (so we're in the blunt object's reference frame). The "ground" is of species 1 (alpha1), the wind-tunnel (or atmosphere) is of species 2 (alpha2) and the blunt object is spewing species 3 out of its' side at 40m/s (alpha3). So, in my back-of-the-envelope calculations (inspired by the User Guide), I set my initial value of k=2.5 and epsilon=0.25. I also set the initial time-step to 0.005sec, and for the sake of early testing I turned off "adjustTimeStep." With all of that said and done, it only completes one iteration of calculation, the output for which is here: Code:

Greetings Edward,
OK, if you've read about the Courant number, then you should know that you should check the smallest cell size you've got:
Oh, and if checkMesh tells you that you've got bad cells or faces, then that's another source of your problems Best regards, Bruno

However, I've since decided to go a different route because this takes a painful amount of time to process. I had interFoam running on this large mesh (see checkMesh output below) on 8 CPUs, left it over-night and it had only gotten to 0.08sec by the following morning. Since my goal is a steady-state solution, I think what I want to try is to add the phase mixing of interFoam to the SIMPLE solver of simpleFoam. I took a quick look at it yesterday, and it seems like it will be a formidable task. Any insight on the matter before I hit the ground running? Thanks! ~Ed |

Hi Edward,
Mmm, you forgot to attach your checkMesh log. Anyway, if you want the steady state solution with interFoam, then probably this is what you want: http://www.openfoam.org/version2.0.0/steady-vof.php Best regards, Bruno
