Matter flow by surface diffusion (solid state): implemented by using the Finite Element library
CIMLIB
3D case involving a small number of grains
2D case (cuvature level sets) with a given distribution of the grain size, and without taking into account the grain boundaries.
3D case involving 370 grains, without representation of the grain boundaries.
Simulations of resin infusion through a porous medium (fibers). These simulations have been carried out during the G. Pacquaut PhD thesis, using the
Zébulon
F.E. software.
2D case: the resin (red part) is injected into the computational domain. The resin flow is described by the Stokes system in the upper part of the domain (purely fluid part), while it is governed by the Darcy's equations in the lower part (porous medium). The black line represents the zero level set of a signed distance function, denoting the separation between the purely fluid subdomain and the porous one, onto a single mesh.

Paper
Droplets, which initially are cubic, are spreading on a rigid substrate, with only capillarity effects as driving force. Three cases: hydrophilic surface (red), hydrophobic surface (blue) and coalescence of two droplets on hydrophilic surface.
