Structural analysis up to 100× faster
RISTRA (Rapid Interactive STRuctural Analysis) is a software for high-performance structural analysis based on the finite element method (FEM). Our specialized algorithms and data structures are optimized for massively parallel execution to leverage the high performance and energy efficiency of graphics processing units (GPUs). RISTRA accelerates structural analysis simulations by a factor of up to 100 compared to commercially available software without loss of quality. For example, the simulation of a wheel rim designed by RONAL GROUP was accelerated by a factor of 93. With sufficient GPU memory, RISTRA can solve problems with more than 10 million degrees of freedom.
We achieve this significant acceleration with our novel, massively parallel solver for linear systems of equations arising in structural analysis simulations, as well as GPU acceleration of all steps in the FEM, including matrix assembly. This minimizes expensive data transfers between GPU and main memory.
