Three dimensional particle simulation of input cavity for S-band long-pulse high-current RKA is presented. First three-dimensional model of open cavity for input cavity is established and resonant frequency and loaded-Q of open cavity is calculated. Raising the beam voltage and beam current from 600 kV, 5.4 kA to 837 kV, 12.48 kA, three-dimensional Particle-in-cell(PIC) code can run stably for 100 ns. The modulated current of simulation is consistent with experiment result. With the structure unchanged, raising the beam voltage and beam current from 837 kV, 12.48 kA to 900 kV, 16 kA, the code can only run stably for 50 ns because of the mode competition. In order to conquer the mode competition, changing the coupling-hole to symmetric double coupling-hole, the code can run stably for 100ns
