How does steady-flow formula influens stresscontroller?
In the TriaxialStressController.cpp, there is a statement and comment
previousTranslation[wall] = (1-wallDamping)*translation*normal[wall] + 0.8*previousTranslation[wall];// formula for "steady-flow" evolution with fluctuations
, which controll the wall position according its destination pressure.
What I want to know is where is the formula from? Is any papers or any books referrence available can explain it more clearly?
Thanks in advance!
