We introduce the Trajectum framework, a new heavy ion code which incorporates many of the necessary components to perform a heavy ion collision simulation in one executable. We use Trajectum to study a generalization of the TRENTo initial conditions, namely varying the free streaming velocity $v_\text{fs}$. In addition, we show the results of a Bayesian analysis performed with this generalized model. This gives mild constraints on second order transport coefficients, and additionally gives a hint suggesting fast hydrodynamization.
