GEMSEO stands for Generic Engine for Multi-disciplinary Scenarios, Exploration and Optimization.
Built on top of NumPy, SciPy and Matplotlib libraries, this Python library enables an automatic treatment of design problems, using design of experiments, optimization algorithms and graphic post-processing.
What is GEMSEO used for?¶
From this information, GEMSEO carries out the following steps:
Create a scenario, translating this design problem into a mathematical optimization problem. The user can choose its favorite MDO formulation (or architecture) or test another one, by simply giving the name of the formulation to the scenario. Bi-level MDO formulations allow to use disciplines that are themselves scenarios.
Plot the results and logs of the optimization problem resolution.
The power of GEMSEO¶
GEMSEO aims at pushing forward the limits of automation in simulation processes development, with a particular focus made on:
the integration of heterogeneous simulation environments in industrial and research contexts,
the integration of state of the art algorithms for optimization, design of experiments, and coupled analyses,
the automation of MDO results analysis,
the development of distributed and multi-level MDO formulations.
