Abstract :
Appropriate dealing with boundary conditions is very important for SPH. Current boundary treatment methods like boundary force method, ghost particle method and virtual boundary layer method, when dealing with complex boundaries, they will have to compute much on putting external particles. For resolving this problem, we propose a new method assuming part of boundary surface instead of external particles, called effective force surface, directly repels the internal particles which approach sufficiently close. We call this new method EFS method. It is implemented in the SPH model for simulating fluid in rabbit-type cup and dam-breaking. In the former case, liquid flows vividly and no internal particles penetrate boundaries. In the latter case, the result is similar to existing result. The experimental results show that EFS method can effectively and precisely deal with complex boundary conditions.
