  • 100% 100%

  • 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 1million DoF (Degrees of Freedom). This reduces the need for simplifcations and modeling 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 the computer hardware requirements.

    • 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.
