**Abstract**

This chapter provides essential information regarding calculation of main forces acting on a body when going through a fluid. Drag and lift coefficients are analyzed with a finite-element method (FEM) Software using an incompressible computational fluid dynamics (ICFD) simulation. A sphere is analyzed and simulated as static object immerse in a fluid. Results are validated by comparing them with the experimental ones found in literature. Efficiency of simulations is demonstrated by close approximation to experimental results.

**Keywords:** computational fluid dynamics, ICFD, finite-element method, drag force, drag coefficient, lift force, lift coefficient
