open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all

I have been following the method decribed in post #745 and the following trail, to supply values for U and V separately at a liquid boundary (rather than velocity normal to the bounday).

I thought I had it right but I still have compilation errors.

I created a liquid boundary file with required VTU(#) and VTV(#), created functions VTU and VTV (copied from vit) amenduimg FCT as suggested, and included them in my fortran file. I also ammended BORD to read VTU and VTV with:

IF(PROVEL(NUMLIQ(K)).EQ.1) THEN
UBOR(K,1) = VTU(NUMLIQ(K),NBOR(K))
VBOR(K,1) = VTV(NUMLIQ(K),NBOR(K))

There are other declarations required for my functions vtu and vtv (interface_telemac2d.f ??). I would be very grateful for any help with where the declarations should be made or if a different way of achieving the time varying unput of U and V at a liquid boundary is possible.

Thanks
John

Hello,

you do not need interfaces but since your VTU and VTV are FUNCTION (presumably) returning DOUBLE PRECISION, you need to add them to the declaration of BORD, in addition to the EXTERNAL statement:

DOUBLE PRECISION VTU,VTV
EXTERNAL VTU,VTV

Hope this helps.
If not, please provide the compilation error and your PRINCI file.

Sébastien.

Thanks Sebastien
They are FUNCTIONS - I have declared them in Bord as you suggest.

That is much better - but I have one compilation error as it looks for VIT = VITES(I) in t2dfort.f

t2dfort.f(471): error #6404: This name does not have a type, and must have an explicit type. [VIT]
VIT = VITES(I)

---

^
compilation aborted for t2dfort.f (code 1)
ERROR : COMPILATION

Can you suggest how to overcome this error please??
John

You may still have the line VIT = VITES(I) in your VTU or VTV functions, which you can replace by VTU = VITES(I), and/or VTV = VITES(I), appropriately.

Also, make sure you have deleted the follwoing line from your new functions:
USE INTERFACE_TELEMAC2D, EX_VIT => VIT

Note that it would be easier for me to get your PRINCI file -- if you can share this with us.

Hope this helps.
Sébastien.

Hi Sebastien

Thank-you - those modifications have worked. The file compiles.

Maybe my fortran file did not upload on the last post - attached again for completeness.




Thanks for your help.
John

Thank you for the PRINCI John. It worked in your previous attempt, it is just that I did not look properly.

Glade it works.
Sébastien.
