Documentation du code de simulation numérique SUNFLUIDH

This data setup defines the domain size, the grid data, the domain decomposition features (MPI parallelisation characteristics : number of MPI processes bounded to subdomains and how they are distributed over the domain) and the number of threads also used to split the domain (OpenMP parallelisation).

• Type : integer value
• This option selects the type of geometry configuration used :
  • 0 : Cartesian geometry
    • 1: Cylindrical geometry. The axis is oriented along the K-direction. The coordinate system is $r(i), \theta(j) , z(k)$
    • 2: Cylindrical geometry. The axis is oriented along the I-direction. The coordinate system is $r(j), \theta(k) , z(i)$
    • 3: Cylindrical geometry. The axis is oriented along the J-direction. The coordinate system is $r(k),\theta(i),z(j)$

• Type : real value
• Origin coordinate along the I-direction.

• Type : real value
• origin coordinate along the J-direction.

• Type : real value
• origin coordinate along the K-direction.

• Type : real value
• End coordinate along the I-direction.

• Type : real value
• End coordinate along the J-direction.

• Type : real value
• End coordinate along the K-direction.
