MODEST Working Group 7:
Validation

The evolution of dense stellar systems is such a complicated problem that no exact solutions and few exact constraints are known. Therefore the reliability of simulations can best be checked by cross-validation. The aim of this working group is to compare results from different simulation methods on a small suite of well specified test problems. The results can be used to check that a new code is working correctly, or that approximate methods give results consistent with more elaborate methods.
