hello everyone!
I try to conduct the some triaxial tests of the granular material under the large strain rate. At initial stage, I find that the domain-servo will be more adaptive to this issue than the wall-servo. However, although the domain-servo is used, the lateral stress couldn’t be constrained in an acceptable value(error<4%?) and improve quickly(shear-rate:2% inertial number:0.05). so is there any approach to make this loading possible?
In addition, I also modify the servo gain here, but not good.
Any comments will be much appreciated
Hello @LJYpyu,
It’s difficult to say what the solution to your problem is without seeing your model. I’d suggest sending this to pfcsupport@itascacg.com, along with the relevant data files. Also, looking at the documentation there is an example that using periodic boundaries and a FISH servo that my help with your modeling questions - Genesis and Testing of a Soft-Bonded Material — Itasca Software 9.0 documentation
Thanks for the reply, this problem has been solved. thanks for your attention! And the documentation is benefit here
