We use the command 'EDCGEN' to define the frictional coefficients in ANSYS
LSDYNA.
Basically we insert the value of the static friction coefficient 'FS' , The
dynamic friction coefficient 'FD' and the exponential decay coefficient 'DC'.
ANSY LS DYNa in turn computes 'internally' (in its hidden code) the coefficient
for viscous friction using the formula:
mu = FD + (FS-FD) e ^(-DC*V_rel)
my question, if i have my own formula, which is dependant on ball center
instantaneous velocity , time, and other parameters, how can I incorporate it
into ansy LsDyna?
I am simulating the impact of sphere with rigid ground
