open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

According to the manual "Adding a particle transport module to Telemac2D with applications to algae blooms and oil spills", the kerosene spill in artificial river used 1156 drogues whereas heavy fuel spill in Gironde estuary used 961 drogues. I am currently running an oil spill simulation. May I know how to determine the number of drogues used? Or how to predict the exact number of drogues to be release?

Thank you

Hello

Sorry for this late reply.

The number of drogues depends on several parameters you need to take into account.
The first point is the quantity of oil spilled. The bigger is the quantity, the bigger should be the number of drogues. This is due to the increasing complexity of the dynamics of the drogues when these latter are representing a huge quantity of oil.
The second crucial point is your computer resources. The bigger is the number of drogues the more expensive is the computation.

What we recommend, is to start with a raisonable number of drogues and to see while results are obtained if oil behaving is efficiently described, if not, increase gradually this number while keeping in mind the limits of your computer.

I hope that this helps

with my best regards

Hi
I would like to ask base on the example estu_gir, may I know how can the user find out the spreading of oil after certain time step as well as how to simulate the dissolution process? I tried running the example but all I get is the particles moving without the dissolution part.
