Fem of electrospinning compared to inkjet printing model
Electrospinning is a process that uses electrostatic forces to produce nanofibers, or fibers in the nano scale. Nanofibers are widely used in many fields like drug delivery and tissue engineering. Nowadays, it is gaining much attention in the research community as an advantageous process. However, …

A fast enriched FEM for Poisson equations involving interfaces
We develop a fast enriched finite element method for solving Poisson equations involving complex geometry interfaces by using regular Cartesian grids. The presence of interfaces is accounted for by developing suitable jump conditions. The immersed boundary method (IBM) and the immersed interface …

Error Assessment in FEM Calculations of Flows with Moving Boundaries
A Finite Element numerical method has been developed to simulate the fluid flow over two dimensional and time dependent domains with rigid moving objects or boundaries. This method falls under the general category of Arbitrary Lagrangian Eulerian methods. In this method the global mesh is fixed and …

A New Singular S-FEM For The Linear Elastic Fracture Mechanics
A new approach of singular S-FEM has been proposed in this dissertation for the linear elastic fracture mechanics problems in both two and three dimensional spaces. A softer model than that of FEM has been developed by using strain smoothing technique on a set of non-overlapping and no-gapping …
