open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear All,

I want to know is it possible to find out dispersion coefficient from Telemac 2d which will be useful for modelling dredged spoil disposal.I also want to know Elder's criteria is useful for creeks.

Thanks in advance.

Hello,

The dispersion coefficient is in array VISC (a BIEF_OBJ object, so real data are into VISC%R, see guide for programming). With Elder's model, it has a second dimension equal to 3 (because diffusion is then like a symmetric tensor). You can get the diffusion coefficient in the results file by adding D in the list of VARIABLES FOR GRAPHIC PRINTOUTS and it appears in the selafin file as the variable VISCOSITY. No idea for Elder in creeks.

With best regards,
