Hi, I would like to know how to create a "no reflection boundary" in AUTODYN. at present I am using no boundary conditions, which results in stress waves being reflected from the model boundary and interfering with my simulation. Even if I use a "constant stress" boundary and set the stress to zero, the reflection happens. I have seen in some papers that no reflection boundaries have been used in AUTODYN, but how i cannot figure out. Can anyone help me? Thanks in advance for any assistance.
