Pithia-FSI is a Boundary Element Method (BEM) solution, that analyze the behavior of fluids, such as water or oil, in porous media like soil, rock, or sand. In these simulations, the soil is typically represented by a porous medium, and the fluid flow is described using equations based on fluid mechanics principles. The simulation results can provide important insights into the behavior of fluid-soil systems, including fluid migration, saturation, pressure, and flow rate, which can inform design and management decisions.

More about BEM
Top-class Accelerated BEM solver
PITHIA’s solver offers unprecedented capabilities to the user over the competition:
1. Based on the accelerated Boundary Element Method, it is capable of solving complex models corresponding to more than 1 million DoF (Degrees of Freedom). This reduces the need for simplifications and modelling assumptions. Instead, it increases the confidence & accuracy of the computed results.
2. By implementing innovative numerical techniques, it offers drastically faster solution times.
3. It minimizes computer hardware requirements.
Solve fast & accurate, with less hardware demands
PITHIA-CP drives innovation in Digital Twins of Cathodic Protection systems and provides unprecedented capabilities compared to the competition.
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.
