The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Some basic formulations of the virtual element method (VEM) for finite deformations (2017, background): “For instance, polygonal and polyhedral finite elements have been shown to better capture crack propagation and branching in computational fracture simulations [1, 2, 3, 4], to produce numerically stable results in topology optimization [5, 6, 7] and fluid mechanics [8], and to better model contact [”
