PyFrac: A planar 3D hydraulic fracture simulator
, 2020 Fluid driven fractures propagate in the upper earth crust either naturally or in response to engineered fluid injections. The quantitative prediction of their evolution is critical in order to better understand their dynamics as well as to optimize their

Towards active microfluidics: Interface turbulence in thin liquid films with floating molecular machines [PDF]
, 2008 Thin liquid films with floating active protein machines are considered. Cyclic mechanical motions within the machines, representing microscopic swimmers, lead to molecular propulsion forces applied to the air-liquid interface. We show that, when the rate
