Dear All,

I have a problem running telemac3d v8.1{1,2} with drogue on HPC. I simulate an estuary and each hour one float is released in the river mouth. In the cas file NUMBER OF DROGUES = 100.
After about 20 days of simulation the model is crashed with error:

application called MPI_Abort(MPI_COMM_WORLD, 2) - process 21

and in the file PE00127-00021.LOG I got:

PARTICLE IN 139 SUB-DOMAINS

But --ncsize 128 !

Any ideas what's wrong?

Thank you
Alexander

(mod(AT, t_step) < 0.5*timeStep)) then CALL ADD_PARTICLE(x_coord, y_coord, z_coord, LT, & NFLOT,NFLOT_MAX,XFLOT,YFLOT,ZFLOT,TAGFLO, & SHPFLO,SHZFLO,ELTFLO,ETAFLO,MESH3D,NPLAN, & 0.D0, 0.D0, 0.D0, 0.D0, 0, 0) end if and I suppose NFLOT_MAX is NUMBER OF DROGUES Thank you
