Dear all,

I’m using Yade to simulate some mechanical experiments such as Direct Shear and Uniaxial Compression of geotechnical materials. There are at least 100,000 particles in the model, as a result, it takes about 4 days or even more to complete one simulation although I have used 8 cores with a desktop computer (8 cores ; Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz 3.70GHz) . So I’m considering rewrite the mainly time-consuming part of code in the calculation with CUDA to achieve a much higher efficiency, for example the part of contact detection. Now I have several questions to consult: 1、Whether this idea is feasible and what degree of workload will be? 2、What’s the structure of the source code like? 3、If I want to speed up the part of contact detection may I only need to rewrite the corresponding code of that part? And which file is this part of code in?
Thanks a lot for your help in advance.

Ocean
