1.3 billions particles

30x GPU 92% Scalability 

An innovative meshless and massively parallel code for modeling materials and structures under extreme loads

92% Scalability @ 256x GPU

INNOVATIVE MESHLESS TECHNOLOGY

ABSTRAO uses cutting-edge ɣSPH computing algorithms to deliver high-fidelity simulations with unprecedented speed and accuracy.

Triple Point Shock

YOUR KEY TO ADVANCED SIMULATIONS

Traditional mesh-based simulations can be limited when modeling complex applications with issues such as mesh distortions, numerical diffusion, and computational overhead. ɣSPH overcomes these obstacles by integrating a robust meshless method that allows detailed modeling of multi-scale phenomena.

ACCURACY AND SPEED

Conventional meshless codes are not suitable for solid mechanics applications.
The ABSTRAO solver, which uses our unique high-order ɣSPH approach, solves all accuracy and stability problems, including those related to tensile instability.
