GANDALF

Overview

Details

• A 1-D description of the CICC, including the possibility of separate treatement of a separate cooling passage (see e.g. the ITER conductors) with independent flow and thermodynamic conditions.

• Modular conductor. The user selects the components and materials forming the cable (superconductor and stabilizer) and the jacket (structure and insulation).

• Variations along the cable length of conductor and helium channels properties. The user is free to change arbitrarily the channel and cable cross sections, hydraulic impedance, channel perforation and wetted perimeters along the cable length (e.g. to model joints).

• Power-law dependence of the longitudinal electric field in the superconductor and consistent current sharing model, for the accurate description of operating conditions around the current sharing regime (e.g. critical current measurements and stability transients).

• The solver uses finite elements in space and finite differences in time. Mesh adaptivity is used to cope with large gradients in the solution.

• An automatic check is performed in the integration on the amount of numerical error introduced in the solution, a very usef tool to qualify solution.

• Extensive user's defined routines to allow easy-to-use interfacing to user's specific applications.

• Graphic (Postscript) post-processor included in the package.

Examples

• a calculation of temperature profiles in helium II

• the simulation of the QUELL experiment
