[求助]
急！求助ANSYS/LS-DYNA高手，计算总是出错out-of-range velocities
|
|
slave surface of interface = 1 type = 14 surface timestep = 6.422E-04 controlling slave node ID = 2 part ID of slave node = 1 current minimum time step = 6.422E-04 master surface of interface = 1 type = 14 surface timestep = 8.102E-04 controlling master node ID = 18731 part ID of master node = 2 current minimum time step = 6.422E-04 The LS-DYNA time step size should not exceed 6.422E-04 to avoid contact instabilities. If the step size is bigger then scale the penalty of the offending surface.
