open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear telemac users,

I am using Telemac V8P4.
I am conducting morphodynamics simulation considering both bedload and suspended sediment using Telemac2d and Gaia.
The settings are as indicated in the cas file attached here, which is as follows in brief:
1. Bedload employs the MPM formula, while suspended sediment uses the van Rijn formula.
2. To prevent erosion at the upstream boundary, EQUILIBRIUM INFLOW CONCENTRATION is activated.
Upon initiating the calculations, the following errors occur. The following is part of the error message. The full messeage is attached as a text file.
What modifications should I make to the cas file?

Could you please provide guidance?

Hello Ryota,

The number of columns in steering files is limited to 72.
I suggest you to read the user manuals to avoid classical errors.

Hope this helps,

Dear Pham,

Thank you for providing that information.
Your point is documented in the TELEMAC2d user manual on page 15.
Following the user manual, I was able to proceed with the calculations without errors after rewriting the steering file, as demonstrated in the example below.

(before)
CLASSES SEDIMENT DIAMETERS = 0.00030; 0.00060; 0.00120; 0.00240; 0.004750; 0.009450; 0.01890; 0.1500
(after)
CLASSES SEDIMENT DIAMETERS=
3.D-4; 6.D-4; 12.D-4; 24.D-4; 475.D-5; 945.D-5; 189.D-4; 15.D-2

Thank you for your prompt advice. I always find your numerous comments on the forum helpful.

Best regards
Ryota
