Hi, I would like to ask regarding the example of oil spill steering file regarding the number of drogue that was use for the case of estu_gir.cas file example which was 961. Can anyone please explain why the number is 96 here and in the riv_art example the no. of drogues is 1156? Is there any reason that this particular number was used?

If you look at line 124 in file t2d_estu_gir.f NUM_MAX=INT(SQRT(REAL(NFLOT_MAX))), sqrt(961) simply gives you an integer. But this is important because the initial mass of each drogue is calculated in line 181 by PARTICULES(NUM_LOC)%MASS0 = (VOLDEV*RHO_OIL)/NFLOT_MAX.

File t2d_estu_gir.f gives you an example to add all oil drogues at a single time step. If you change your addition logic (e.g. multiple time steps), you need to ensure the total number of drogues equals the number you input in case file.
