I think that the problem is the courant number, that at a certain time goes above 1... I have already refined the time step and the problem just shifted from 0.036 to 0.040 (of the "real" time of the phenomenon that I have to simulate). It took me a week of simulation, so I can't refine that much...

I attach here two file showing the Co values with respect to the inlet velocity values.
Thanks for helping me

Thanks in advance for your reply
Ceren

Your Courant Numbers (entries in bold) and timestep continuity errors are huge. This suggests:
  1. Your time step for the cell sizes are not compatible. Try reducing the timestep.
  2. There's something that's causing imbalance in the system and increasing the continuity error. Take hard look at the boundary conditions again. See if all patches are correctly defined.

Hi All


this is a great thread, old though it may be, and very informative.
I will start with my problem. I am trying to run buoyantSimpleFoam on a engine test cell. I am not modelling flow in the engine. Instead I have no mesh where the engine sis. Instead i have inlet and outlet boundaries for the engine inlet and outlet. I am trying to see re-circulation within the test cell (room).

I started out the simulation with just simpleFoam, to see if a cold flow run would work,. yeah success.
Then i added turbulence to the mix and also success.
The final step was adding heat, so i switched to buoyantSimplefoma as the temperature difference between the room and engine exhaust was greater than 10 degrees. Below you can see the last section of my log file. I am getting a floating point exception. So there are some odd maths going on.

Code:
Time = 5

DILUPBiCGStab:  Solving for Ux, Initial residual = 0.181033, Final residual = 3.19602e-05, No Iterations 1
DILUPBiCGStab:  Solving for Uy, Initial residual = 0.236924, Final residual = 6.02134e-05, No Iterations 1

Floating point exception (core dumped)
My first stop was checkMesh which said i had a good mesh (created with snappy).

After reading through this thread i followed the crumbs and saw my epsilon was going negative. And this knocked on to how my p_rgh was being calculated. So i now assume i have the wrong boundary condition epsilon and k. I have attached the patch summary and the log file of the simulation run. If anyone could please advise on what i am supposed to use for boundary conditions i would be very grateful.
For reference my patches are named:
Quote:
Box_Wall, Box_rig - walls
Box_inlet - air inlet from atmosphere
Box_outlet - air outlet, suction based with volume flow rate
Box_port - inlet/outlet not sure - exposed to atmosphere
Box_t_in - engine inlet, modeled as suction outlet
box_t_out - engine outlet,
Box_exhaust - outlet exposed to atmosphere,

Look fwd to your help

Hi Gareth,


I am also experiencing a similar error when I try to run buoyantSimpleFoam. I am very new to OpenFOAM. My problem is that of a heat exchanger (cold cylinder) in hot flow. For the moment, I am only looking at a 2D problem. In order to familiarise myself with OpenFOAM, I first tried to work on the cold flow case using simpleFoam and it works fine. The moment I add heat transfer, it goes bonkers and I am not able to understand the error.


From what Bruno mentioned in the beginning of the thread, all I could gather was that somewhere in my code there is some nasty math happening. But I am not able to figure out where. I am also not very confident with my BCs. I thought flow over a cylinder with heat transfer is sort of a standard problem that many people must have worked on. Unfortunately, the countless hours spend on the internet trying to figure out the BCs didn't help me much. Eventually, I decided to follow the example of CicuitBoardCooling in the tutorials. But, still going nowhere.


If somebody wants to see how my domain looks like, it is nothing but a half cylinder with symmetry conditions on the top and bottom wall. There is a velocity inlet and the pressure is assumed to be constant. The flow is hot and the tube is cold with a fixed temperature prescribed to it. I would have included the schematic if I knew how to include as attachments. Hope somebody can help me with that as well.


If somebody is willing to have a look at my codes, do let me know, I can post them here.


Cheers!

Dear ASurendran, Just check out the boundary conditions for pressure and velocity you have given. The solver you had mentioned here is default available in OpenFOAM, so there is no doubt regarding accuracy. the only thing here can be modified is pressure velocity, and temperature BC. Therefore have a look on in-built bouyantSimpleFOAM tutorial.

Hi Ranjit,


Thank you for the reply. The closest tutorial that I can compare with my case is that of CircuitCooling. Shown below are my P, T and U codes. I am really doubtful of how to define p_rgh though, as this concept is a bit tricky for me to grasp. Is p_rgh really pressure? what value should we give? etc.

Hi ASurendran
In my case there were some poor cells causing me trouble. while checkMesh gave me the all clear, a personal inspection of the mesh showed me what to fix.
But i think the boundary conditions are usually a culprit. If you want to eliminate meshing as a possible source try a very simple setup with well defines cells...

Hi Gareth,


Thank you for your suggestion. I will check the mesh and BCs as suggested.


Kind regards

Hi All,


I forgot to mention that I work on High pressure flows with high temperature differences i.e., my domain pressure is of the order of 10bars and the difference in temperature between the flow and the heat exchanger is around 1100K. Has anyone encountered such situations?


To Gareth - I tried other possible BCs. Sadly, none of them worked.

HI,


I am having the same type of issue (parallel mode), but it works fine in serial mode.

mpirun noticed that process rank 4 with PID 0 on node ufifilters-HP-Z4-G4-Workstation exited on signal 8 (Floating point exception).





And one more thing, I tried to compile the openfoam in debug mod but it failed, couldn't compile.




How do I look up at this problem?

Govind
