open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello all,

According both the telemac2D manual and the paper regarding the algae transport module, the "STOCHASTIC DIFFUSION MODEL" option can take the values 0 or 1. However, FUDAA gives the possibility to choose between 0,1 and 2, without any comment to describe each option. In addition, lines 114,115 in charac.f are:
Which is the correct/proper option for algae transport modeling?

Best Regards,
Costas

Hello Costas,

This is an error in FUDAA, and in the charac.f comments.

"STOCHASTIC DIFFUSION MODEL" can only take option 0 or 1, which serves to define if brownian motion is taken into account or not.

To model algae, you need to use the following keywords:

• NUMBER OF DROGUES (= number chosen by the user)
• PRINTOUT PERIOD FOR DROGUES (= number chosen by the user)
• DROGUES FILE (= name chosen by the user)
• ALGAE TRANSPORT MODEL (= 1 to define algae transport)
• ALGAE TYPE (= option chosen by the user)
• DIAMETER OF ALGAE (= value set by the user)
• DENSITY OF ALGAE (= value set by the user)
• THICKNESS OF ALGAE (= value set by the user)

Thank-you for spotting the errors, I will see how to correct them.
