Hello,


I am currently trying to use an tracer to find the residence time within a certain region of my domain. To do so I run an unsteady simulation to stabilise the flow and then I patch the tracer and run with multiphase turned on and data sampling turned on. Since my domain requires a periodic condition I have to keep deleting my tracer on inlet by an automatic command, and hope that the flow is sufficiently stabilised since I lose capabilities of controlling the flow by mass due to multiphase.


The problem is that once I read the case of the second simulation and the data from the first, I can't continue calculation due to the error:

Node 0: Process xxxx: Received signal SIGSEGV
MPI Application rank 1 exited before MPI_Finalize() with status 2
The fl process could not be started.

I found it odd since I always ran simulations with parallel fluent and this never occurred before. Does anyone have an idea of what can be done?


So far I've tried running on serial, turning off my automatic commands and redistributing partitions without success. I can manage to run both simulations individually but not together.
Also if there is a better way on finding Residence Time Distribution I am accepting suggestions.


Thanks!
