High density crowds are risk situations that already had turned some events into disasters. There are particular emerging events in these crowds that had led to dangerous situations. One important phenomenon is named “crowd turbulence”. It is produced by a propagation of forces among the mass and has already been the cause of several tragedies. We present a new approach to its representation and understanding by a hybrid model composed by two parts: physical interaction among the agents, and psychological factors that produce voluntary interactions. The focus of the present work is contributing with a model able to reproduce such events in a computationally efficient way on SIMD architecture
