no error message but why it doesnt continue calculating

My liggghts always works, but today when I changed Young's modulus from 5e6 to 20e9（I am using Hertz model to simualte sand particles）. It stays at step one and there is no error message. I waited a long time, it;s still at step one. Can anybody guide me ?Appreciate it!!

Thanks

Hi xiaobaishu,

my guess is that the simulation blows up because your time-step is too long, your simulation box is exploding because you have "boundary m m m" and you're just waiting forever to finish the first couple time-steps
