Examples of developments:

• Development of a Vlasov 2D semi-lagrangian type code, to discover new phenomena and plasma regimes and 3D code extension (implementation of diagnostics, new parallelization layer)
   
• Development of a code simulating the electromagnetism of plasma excitation structures
   
• Development of a code to melt and solidify a metal substrate immersed in a liquid and subjected to a plasma
   
• Development of codes to determine the conversion potential of thermoelectric generators and the prediction of their electrical performance (co-supervision of a thesis 2016-2019)
   
• Development of a thermo-acousto-fluid model for the magnetic labelling of cells, magnetic trapping, differentiation of cells by a piezoelectric sensor
   
• Development of software for modelling the process of hydrofluorination of uranium dioxide to uranium tetrafluoride in a moving bed furnace, in collaboration with AREVA, training of industrial users
   
• Optimization, maintenance, testing and industrialization of software simulating the vacuum arc remelting process or the electroslag remelting process
