LOQUAT: an open-source GPU-accelerated SPH solver for geotechnical modeling

Chong Peng, Shun Wang, Wei Wu, Hai-sui Yu, Chun Wang, Jian-yu Chen
2019 Acta Geotechnica  
To promote the research and application of SPH in geotechnical engineering, we present LOQUAT, an open-source three-dimensional GPU accelerated SPH solver.  ...  LOQUAT employs GPU acceleration technique to greatly increase the computational efficiency. Numerical examples show that the solver is convergent, stable and highly efficient.  ...  To this end, acceleration techniques such as multi-thread CPU computing and GPU acceleration are necessary for SPH to achieve reasonable computational time.  ...
