Backtrace errors while running on a HPC with buoyantBoussinesqSimpleFoam
 

I saw a similar error these days. Have you found an answer?

Hi,

I did not go much into details but I understood (after some googling!) that
signal 7 is a bus error. Which you can see from:

--------------------------------------------------------------------------
mpirun noticed that process rank 61 with PID 10107 on node e530 exited on signal 7 (Bus
error).

I am not sure about the details though. However, some explanations for the bus error:

A "Bus Error" may come, for example, from accessing unaligned data (i.e. like trying to access a 4 byte integer with a pointer to the middle of it). What this means will vary from platform to platform. (I haven't come up with a good example of this one yet.)

A "Bus Error" can also often indicate a memory overwrite, e.g. somebody wrote a number where a pointer is kept. Often caused by going past the end of an array and into the system pointers at the start of the next memory block.
