Local variables to be added

Initialization

One can get any field using cs_field_by_name function (use cs_field_by_name_try if one is not sure the field exists). "scalar1" is the name related to the first user-defined scalar variable. f->val[cell_id] is the value of this variable in cell number cell_id.

ONLY done if there is no restart computation.

  const cs_mesh_t *m = domain->mesh;

  /* If this is restarted computation, do not reinitialize values */
  if (domain->time_step->nt_prev > 0)
    return;

  /* Initialize "scalar1" field to 25 only if it exists  */
  cs_field_t *f = cs_field_by_name_try("scalar1");

  if (f != NULL) {
    for (cs_lnum_t cell_id = 0; cell_id < m->n_cells; cell_id++)
      f->val[cell_id] = 25.;
  }
