This chapter discusses some sample problems varying tubing size and surface pressure with different inflow expressions. Nodal Analysis is used to examine the effects of variables that control the number of perforations, surface pressure, and tubular sizes, when a well or considering tubing re-size. ...
Numerical experiments are done demonstrating the theoretical error estimates. The performance of the method is illustrated in several sample problems.

We focus on the Element-free Galerkin (EFG) method [3]. The EFG method does not depend on elements to discretize the governing equations and is therefore more suited for problems with varying nodal distributions. However, in literature the EFG method is mostly applied to regular shaped domains...

The deviation observed in the solution is discussed, and its cause is further clarified from a two-domain pure magnetostatic analysis of a permanent magnet. It is found that the accurate solution of such problems is associated with discontinuity of the normal component of the magnetic potential ...
