Dear Users,

I m using BlueCFD on windows. The interDyMFoam crashes randomly, and I don't know what could be the problem. I m running on 4 cores, parallel. If I run on 1 core, it does the same thing. Here is the error message I get:

Quick answer and sorry for the late reply: The stack trace line that hints at the problem is this one:
Code:
ZN4Foam6sigFpe13sigFpeHandlerEi [0x1022af3+0x33]
                 module: D:\PROGRA~2\BLUECF~1\OpenFOAM-5.x\platforms\mingw_w64GccDPInt32Opt\lib\libOpenFOAM.dll
Namely "ZN4Foam6sigFpe13sigFpeHandlerEi", where "sigFpe" can be seen in the name. This means that there was floating point exception: https://en.wikipedia.org/wiki/Signal_(IPC)#SIGFPE - usually a division by zero or some other calculation that required the result to be infinite or complex number.

I suspect that this happened due to this:
Code:
AMI: Patch target sum(weights) min/max/average = 0, 2.186797, 1.007601
If a weight is 0, this means that there is a face that is not in contact with another AMI interface. This means that you would have to use ACMI instead, which allows for unmatched surfaces, although the unmatched ones would then be automatically matched to a wall surface... although this doesn't work all that well, at least last time I heard/saw something about it.
