Micro scale simulation

abli

Hello,

I am trying to simulate micro scale floating objects on water surface.

I used the (famous) FloatingCase example as a starter, and everything went well.

However when I shrink the parameters down to micro scale (particle distance is below micro scale), the codes do not work as expected.

I am wondering a) If DualSPHysics allows micro scale simulations; b) What else I should do to make it work? Should I work on refining my model or should I try modifying the source codes?

Any advice would be helpful.

Thank you very much!!

Alex

The issue can be the precision. Current online version 3 of DualSPHysics uses simple precision. Next release, expected by the end of the year, will include double precision for position variables which can solve your issue at a certain level.

Thank you very much, Alex!

This version has helped me a lot and I am looking forward to the new version~
