Anti-Corrosion Design via Cathodic Protection


Superconducting Magnets


Vibro-acoustic Wave Propagation

PITHIA fills the gap among existing software packages and reinforces the simulation toolbox of engineers and scientists

The Boundary Element Method (BEM) is ideal for providing accurate and reliable solutions to large-scale problems dealing with infinite/semi-infinite domains, such as corrosion resistance (e.g. cathodic protection in vessels, tanks, pipelines, oil platforms, bridges), outdoor & underwater acoustics (e.g. infrasound, noise pollution), soil mechanics (e.g. earthquake waves, foundations, vibration isolation), electro-magnetic radiation and scattering (e.g. magnets, radars, antennas), etc.

Why BEM (Boundary Element Method)?

The dominant competing solution is the Finite Element Method (FEM), which generally is very well implemented but has certain limitations in problems dealing with infinite/semi-infinite domains. The method has significantly higher computational requirements, making it unsuitable for e.g. acoustic, vibration wave propagation in soil and electromagnetic problems. PITHIA is based on the Boundary Element Method (BEM), the main advantage of which is the reduction of the dimensionality of the problem. This means that only the boundaries of the problem is required to be discretized in contrast with the FEM where the volume of the e.g. sea, soil or water must be discretized. Thus, the model preparation in PITHIA is significant simpler. Additionally, it well-known that the Boundary Element method offer unprecedented accuracy compared to the Finite Element Method.
