open TELEMAC-MASCARET The mathematically superior suite of solvers

I am going to introduce logarithmic velocity profile in inlet of computational domain. Should I write a fortran file (bord3d.f) or there is a KEYWORD for that?

If I have to write a subroutine code, What are variables of U, V, W in telemac3d (UBORL%R(IBORD), VBORL%R(IBORD), WBORL%R(IBORD))?

I would be thankful if you can guide me.
Best regards,
Mahdi

Hello,

Indeed you are right, you will have to write your own version of BOR3D.
The variables you named are correct, although I would not attempt to modify W.

Also, it may help if after setting UBOR,VBOR, you set U and V at the boundary node (using NBOR) to the same values.

Hope this helps,
Sébastien.

Hello Sébastien

I wrote my fortran File to introduce Log. velocity profile to OpenTelemac .
When I run my cas file, velocity components in entrance of domain are equal to zero during time. So it seems that my fortran file is not correct.
I would be thankful if you could take a look on it and tell me what my problem is.




I will appreciate any help you can provide.

Best regards,
Mahdi

Hello,

Actually you can also use the keyword:
VELOCITY VERTICAL PROFILES =2
The log velocity profile are already progarammed
