ERT - Ensemble based Reservoir Tool - is designed for running ensembles of dynamical models such as reservoir models, in order to do sensitivity analysis and data assimilation. ERT supports data assimilation using the Ensemble Smoother (ES), Ensemble Smoother with Multiple Data Assimilation (ES-MDA) and Iterative Ensemble Smoother (IES).

Clicking "Restart" after a run gives ambigous message #7877

Open berland opened 6 months ago

When clicking "Restart" in the run dialogue one will get the message:

where the text "Note that workflows will only be executed on the restarted realizations and that this might have unexpected consequences" is ambigous. Since workflows in Ert is something you execute on ensembles, it is difficult to understand what this message is trying to convey, is it mixing workflows with forward model steps?

Note also that restart does not do what we want it to do: https://github.com/equinor/ert/issues/8032

I think, but speculating here, that this is to warn of cases where you modify global state. For example in the old scaling job, where the observations were in memory only, and any modification would effect everything. If you were calculating that scaling factor in a workflow based on the running realizations, that would affect the result. Think this is largely removed now though, so suggest just removing the message.
