Abstract
We are pursuing a cross-benchmarking and validation initiative for tokamak 3D equilibrium calculations, with 11 codes participating: the linearized tokamak equilibrium codes IPEC and MARS-F,the time-dependent extended MHD codes M3D-C1, M3D, and NIMROD, the gyrokinetic code XGC[6], as well as the stellarator equilibrium codes VMEC, NSTAB, PIES, HINT2 and SPEC. Dedicated experiments for the purpose of generating data for validation have been done on the DIII-D tokamak.The data will allow us to do validation simultaneously with cross-benchmarking. Cross-benchmarking calculations have been finding a disagreement between the VMEC stellarator equilibrium code and tokamak linearized 3D equilibrium codes. Investigation of the source of the disagreement has led to new insights into the domain of validity of these codes.Conference Dates
