From: Modeling lamellar disruption within the aortic wall using a particle-based approach
Particle arrangement in the SPH aortic model. Particles are categorized into three groups: medial elastin (Mel-red), medial intra-lamellar (Mint-blue), and adventitial (A-green). Also shown is a collection of intra-lamellar particles (orange) undergoing apoptosis and loss of matrix and replacement with GAGs. The kernel support denoted by h determines the number of particles included in each list of neighbors, which allows local smoothing and calculation of continuum quantities from individual particle forces and motions. Particle density is 0.24 per μm2, with individual particle spacing ~2 μm.
