abstract = {<p style="text-align: justify;">A new finite difference (FD) method, referred to as &quot;Cartesian cut-stencil
FD&quot;, is introduced to obtain the numerical solution of partial differential equations
on any arbitrary irregular shaped domain. The 2<sup>nd</sup>-order accurate two-dimensional
Cartesian cut-stencil FD method utilizes a 5-point stencil and relies on the construction of a unique mapping of each physical stencil, rather than a cell, in any arbitrary
domain to a generic uniform computational stencil. The treatment of boundary conditions and quantification of the solution accuracy using the local truncation error
are discussed. Numerical solutions of the steady convection-diffusion equation on
sample complex domains have been obtained and the results have been compared
to exact solutions for manufactured partial differential equations (PDEs) and other
numerical solutions.</p>},
