Chrono/GPUSPH Communication

Applications
1

Hi,

I am investigating some issues with joints defined in chrono and was wondering about the coupling sequence between Chrono and GPUSPH. How often is information passed to/from chrono? And is that a parameter we can change? (similar to simparams()->buildneibsfreq)

Thanks!

Hi Ethan,

The Chrono model is integrated with a single step during the SPH predictor (see fea_do_step in src/ProblemCore.cc). This single step can even cover multiple SPH steps, and you can set this by using the simparam feaSph_iterations_ratio.

Hope this helps,
Vito
