Who can apply me code of FLASH ?

Recently I have some reseach on z-pinned composite. I hope use finite element method to analyse the unit cell . I found a FE code called FLASH mentioned in many papers. I think the code will be helpful to my work.But I can not got the code form my resource. So,I ask help in the forum. Two papers about the code are given in below. I am very expect for your help!!!
