We have the so-called 'diff'-mode in precice-aste-evaluate in order to compute error metrics on our output mesh. The diff mode takes as input arguments the diffdata (data used for the difference calculation) and a function in order to generate reference data. However, computing the difference between two data fields is not possible. We should extend the current CLI to also accept a second ('reference') data field and compute the error between these two data fields instead of an analytic function.
