This paper presents a new approach for simulating the indirect effects of a lightning impact on an aircraft engine. Based on macro-modelling, it performs a model reduction, in a similar way as "stick models", but using a patch support instead. This new macro finite element space allows for fast resolution of the quasi-static lightning injection problem.
