Hi,

Is it possible to set the initial conditions variable in space especially for tracer. I want to have variable initial salinity within the domain as the diffusion of the salinity needs very long time, so having variable salinity value within the space will help in reaching the steady state quickly.

Hello,

You can do what you want in condin.f, by replacing the sequence initialising the tracer with a constant by any variation in space.

Can you please tell me how can I code that in the condin, for instance if the space variation in tracer is according to the following equation:

T = { (X - 14710)^2 + (Y - 35)^2 }^0.5

Where X and Y are the coordinates for each point

Thanks in advance

Hello,

Here is what you can do :

DO I=1,NPOIN
T%ADR(1)%P%R(I)=SQRT((X(I)-14710.D0)**2+(Y(I)-35.D0)**2)
ENDDO

You may have to declare I as an integer. I assume here that you have only one tracer. For a second tracer it would be T%ADR(2)%P%R(I)=... as T is the block of tracers.

You can refer to the programming guide for explanations on blocks.

With best regards,

Hello,

I would like to impose space varying initial conditions for water level and a tracer using the condin.f file. I created .t3s files for both variables on the exact mesh using the BlueKenue software. Now I am looking for an easy way to include these .t3s initial conditions in the condin.f file.

I know that a similar thing is done with the BOTTOM file and the BOTTOM FRICTION file when those are included in the geometry file. However I didn't find how to implement this in the condin.f file.

Thanks in advance!
