Hi all,

I'm having a problem with a version of interFoam that I modified. The error message is pasted below. I can't get my head around what the problem is. I get it at the end of the while(runTime.run()) loop in the solver where UEqn, PISO, etc. run after the first go at it. Might anyone have any suggestions as to where to look next?

Thanks!

Can you show some more of your logfile? What modifications did you make? Did the case run without these modifications?

[robertmaier9]

Thanks for the quick response! I have made some extensive changes. I have added heat transfer into interFoam, which had worked before. Then I added a new method of calculating the heat transfer coefficient at the interface as a subroutine in alphaEqnSubCycle. The first implementation of the internal cells worked. Then I started playing with values on the boundaries, and this is where things stopped working.

I have run this case with different "generations" of this solver, but the most recent version is giving me trouble.

It's safe to say, that I have changed a lot, and one loses a bit of oversight when this happens. I'm going to keep on chuggin' away. Any help would be most excellent!

Thanks.

Hi,

I have narrowed down the problem. The problem occurs when I try to save a value to the boundary fields. I have created a coefficient with the name f1 which is of class surfaceScalarField. When I comment out the follow bit of code, the solver runs. Only when I keep the line(s) active, does the error occur.

f1.boundaryField()[patchID][facei] = f1temp;

Here, f1temp is a double between 0 and 1.

There is no problem with saving it to an internal face as in the next line of code. Only with the boundary.
[CODE]f1[facei] = f1temp;[\CODE]

I've run it on a single cell as well as multiple cells. The error I get for the multiple cells (4x4) is as follows.

alphaSubCycle is now finished
