open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi, when I try to run the validation case of river confluence downloaded from this website, the following information happens, why this happens?
Thanks!

Hello,

It seems to be a problem of configuration. ifort is the command for the Intel Fortran compiler and it seems that it is not installed ?

Hi, Jean-Michel-Hervouet,
Thanks a lot.
When I modify the keyword "FORTRAN FILE=princi.f" in the steering file as interpretation, this problem dissapear.
When I use K-E turbulence model(the configuration in steering file is as following), I want to compare different wall friction. However, when I set the keyword "ROUGHNESS COEFFICIENT OF BOUNDARIES" as 92 and 12 respectively, the velocity results are the same. Why this happens? Thanks.

/try the K-E model
TURBULENCE MODEL =3
TURBULENCE MODEL FOR SOLID BOUNDARIES=2
ROUGHNESS COEFFICIENT OF BOUNDARIES=12
VELOCITY DIFFUSIVITY =1.E-6

Hello,

The default value of the keyword :

LAW OF FRICTION ON LATERAL BOUNDARIES

is set to 0 by default, so you must set it in your case to 5 (Nikuradse law), and the coefficient is then the grain size (roughness of boundaries) so it will not be 92 and 12 but certainly smaller values.

With best regards,

Jean-Michel Hervouet

Hi, Jean-Michel-Hervouet,
Why I cannot find the keyword of "LAW OF FRICTION ON LATERAL BOUNDARIES" in Telemac2d manual?
And, in the 6.2.3 part of this manual, there is one paragraph: "In the case of a solid boundary, the user may configure the turbulence regime for the walls using the keyword TURBULENCE MODEL FOR SOLID BOUNDARIES. If friction at the wall is not to be taken into account, the user must use the value corresponding to a smooth wall (option 1). In contrast, friction will be taken into account by using option 2 (rough wall). In this case, the friction law used for the wall is the same as the bottom friction law (keyword LAW OF BOTTOM FRICTION). The friction coefficient is then supplied by the keyword ROUGHNESS COEFFICIENT OF BOUNDARIES. This numerical value must of course be in agreement with the law chosen, in appropriate units.". This paragraph in the manual means that the friciton law used on the lateral boundary is the same as that on the bottom friction. So, whether it isnot necessary to set the law of friction on lateral boundaries?

The following is the whole part of physical parameters in my steering file.

/

---

/ PHYSICAL PARAMETERS
/

---

/
LAW OF BOTTOM FRICTION = 3
FRICTION COEFFICIENT = 62
/TURBULENCE MODEL = 1
/VELOCITY DIFFUSIVITY = 1.E-3

/try the K-E model
TURBULENCE MODEL =3
TURBULENCE MODEL FOR SOLID BOUNDARIES=2
ROUGHNESS COEFFICIENT OF BOUNDARIES=12
VELOCITY DIFFUSIVITY =1.E-6

Hello,

Yes, this keyword was added in version 6.1 and it will be described in a new version of the documentation that will appear very soon now.
