Hello,
I am using the DMSwarm library in some Eulerian-Lagrangian approach to have
vapor bubbles in water.
I have obtained nice results recently and wanted to perform bigger simulations.
Unfortunately, when I increase the number of processors used to run the
simulation, I get the following error:
free(): invalid size

Primary job terminated normally, but 1 process returned

mpiexec noticed that process rank 84 with PID 590327 on node cns136 exited on

When I reduce the number of processors the error disappears and when I run my
code without the vapor bubbles it also works.
The problem seems to take place at this moment:
DMCreate(PETSC_COMM_WORLD,swarm);
DMSetType(*swarm,DMSWARM);
DMSetDimension(*swarm,3);
DMSwarmSetType(*swarm,DMSWARM_PIC);
DMSwarmSetCellDM(*swarm,*dmcell);
Thanks a lot for your help.
Best regards,
Joauma
