A new 3‐D Fokker‐Planck code, CQL‖, which solves the Fokker‐Planck equations with two velocity coordinates and one spatial coordinate parallel to the magnetic field lines B /B, has been developed. This code enables us to model the parallel transport for low, intermediate and high collisional regime. The physical model, the possible relevant applications of the code as well as a first application, the computation of the neoclassical resistivity for various collisionalities and aspect ratios in tokamak geometry are presented.
