AbstractThe complex problems that computational science addresses are more and more benefiting from the progress of computing facilities (simulators, librairies, accessible languages,. .). Nevertheless, the actual solutions call for several improvements. Among those, we address in this paper the needs for leveraging on knowledge and expertise by focusing on Domain-Specific Modeling Languages application. In this vision paper we illustrate, through concrete experiments, how the last DSML research help getting closer the problem and implementation spaces.
