Female spider eating her partner Mahdi Esmaily 2012-07-13 | That's what will happen if you don't do your job properly!(From Life under growth - 2005)
one sided separator Mahdi Esmaily 2018-08-01 | When inertial particles that differ in size by 1% are placed in a precisely-constructed oscillatory shear flow, they exhibit drastically different behavior and segregate after a few oscillations.
Time-evolution of a cloud of inertial particles Mahdi Esmaily 2015-11-18 | A volumetric mesh, which represents a cloud of particles, is constructed based on a set of inertial particles. As particles move in a turbulent flow, the cloud deforms. This leads to contraction or expansion of cloud, providing an estimate for the divergence of particle velocity field.

Backflow with no treatment Mahdi Esmaily 2015-11-16 | Neumann boundaries are vulnerable to backflow. This video demonstrates vortex shedding can trigger instabilities, causing a simulation to diverge.

FSI simulation of single ventricle physiology Mahdi Esmaily 2014-03-27 | This is stage one patient with a systemic-to-pulmonary shunt. The simulation is performed using fully closed-loop multiscale framework, in which inlet and outlets are all couple to lumped parameter network. Variable wall properties and thickness is used. ALE formulation with St.Venant Kirchhoff model is employed for the solid, allowing to capture large deformation.

Isogeometric analysis for fluid flow simulation Mahdi Esmaily 2014-02-12 | This model is generated using 7 patches. This is a 2D model of ABG, in which flow is injected from a high pressure inlet into a low pressure flow. Colors represent velocity magnitude.
FSI simulation of a flexible beam in crossflow Mahdi Esmaily 2014-02-12 | Vortex shedding generates a fluctuation in pressure distribution on the beam and causes the beam to oscillate.
CFD simulation of Assisted Bidirectional Glenn (ABG) Mahdi Esmaily 2014-01-28 | ABG is a novel surgical concept, intended for palliation of single ventricle heart patients. In the ABG, the SVC is connected to the pulmonary artery and a extra connection is established between systemic circulation and the SVC via a shunt. This video shows high velocity shunt flow that is injected into the SVC.

Multiscale simulation Mahdi Esmaily 2014-01-27 | This is a multiscale simulation of circulation in a single ventricle patient. The flow at the inlet (ascending aorta) and the pressure at the outlets are calculated in a lumped parameter network (LPN) and passed to the 3D CFD domain.
stabilized formulation to prevent backflow divergence Mahdi Esmaily 2014-01-27 | Simulation divergence, triggered by the backflow, is prevented non-intrusively by adding an extra stabilization term to the formulation.
Forcing velocity to be normal to the boundary Mahdi Esmaily 2014-01-27 | While the regular formulation is unstable, forcing the velocity to be normal to the boundary is an intrusive method that changes the flow pattern of vortices that are advected through the outlet.
No stabilization added Mahdi Esmaily 2014-01-27 | Neumann boundaries are vulnerable to backflow. This video demonstrates vortex shedding can trigger simulation divergence, when regular formulation is employed.
Mesh adaptation Mahdi Esmaily 2013-03-28 | Going from 20,000 tetrahedral elements to more than 4,000,000 elements in 5 stages of adaptation. The mesh is mostly refined in regions with high velocity and recirculation.
