  Nowadays we are experiencing a way of life that never existed before. The
pandemic has sharply changed our habits, customs, and behavior. In addition, a
lot of work was suddenly requested for city managers challenging them to
develop strategies to try stopping the pandemic progression. Urban environments
must be dynamic and managers need fast decisions when working on crisis
situations. In this paper we present LODUS, a framework able to simulate urban
environments on a multi-level approach, combining macro and micro simulation
information in order to provide accurate information about population dynamics.
Furthermore, the framework LODUS is a powerful tool when performing an urban
viability study, since the simulation results are able to highlight and predict
attention points prior to an urban environment to be built.
