Hello

The Mascaret solver shows the following error message:

Error with the linear solver DGBSV

Could you tell me the mistake I committed

Best regards

Hello,

it is not simple to give you an answer with this error message. Unfortunately the error code is not printed with MASCARET v7.2. If you can compile MASCARET, try to add the print of this error code in order to have more information about the problem.
(see routine rezo.f90 at line 672 for instance)

Regards

Hello Laurent,

in fact you have a problem with the conveyance calculation in zone #2. The algorithm of the Debord formula is not supposed to be applied with such Strickler coefficients, i.e. when CF2 is greater than CF1. In the next version of Mascaret a test is introduced in order to have a more explicit error message at this level.
