What is FE Tharja?

FE Tharja, in its essence, is a Finite Element Analysis software package designed for simulating and analyzing structural, thermal, and electromagnetic phenomena. While the specific features and functionalities may vary depending on the version and developer, the core principle remains consistent: to discretize a complex structure or system into smaller, simpler elements and then apply mathematical equations to approximate the behavior of each element. These individual element behaviors are then combined to understand the overall response of the system. FE Tharja, like other FEA software, relies on numerical methods to solve complex differential equations that govern the behavior of physical systems.
