The Super Fragment Separator (Super-FRS) will be a part of the Facility for Antiproton and Ion Research (FAIR) placed in Darmstadt, Germany. Super-FRS will have superferric superconducting magnets working in liquid helium. Superconducting magnets need to be protected against quench (unwanted transition from superconducting to normal conducting state). To foresee the temperature distribution and voltage increase during a quench and to choose the best magnet protection system one needs to do the quench calculations before the first test of the magnet prototype.
This work presents a comparison between 2D quench calculations done on FAIR Super-FRS dipole with two different quench programs. The first was developed in GSI. It uses finite difference method and it is based on the heat equation. The second was a commercial FEM (FInite Element Method) software Opera 3D with the quench module. Obtained results are in good accordance between those programs.
