How to define a new vector field and its values?

[Mohammad]

Hi,
I want to create a new vector field like velocity field.
How can I do that? in which file? Is there an example?
Also, I want to know that if I define a field in a C file, can I call and use that field values in a Fortran file?
Thank you

Hello,

You can add a new scalar or vector field in the subroutine cs_user_parameter.c by using the function: cs_parameters_add_variable (name, dimension).

you can find here an example of adding a scalar field: https://www.code-saturne.org/cms/sites/ ... eters.html

And you can get the field values by using the functions:

C function: const cs_real_3_t *cvar_vector = (const cs_real_3_t *)cs_field_by_name("vector_name")->val ;

Fortran function: call field_get_val_v_by_name('vector_name', cvar_vector)

Thanks a lot.
When I use this code:

Code: Select all

cs_parameters_add_variable("vector_name", 3);

The compiler ends with the following error:

Only user variables of dimension 1 are currently handled,
but vector_name is defined with dimension 3.

Where's the problem?

I appreciate your helps.

Hello,

Could you specify at least the version info as per the forum usage recommendations ?

Sorry,
My version is 5.0.9.

Hello,

Looking at the code, it seems you can add a user vector in version 6.0, not in 5.0.
