各位大佬，LS-DYNA求解器的CESE模块，出现这个问题The LS-DYNA time step size should not exceed 1.026E-06 to avoid contact instabilities.

If the step size is bigger then scale the penalty of the offending surface.

The LS-DYNA time step size should not exceed 1.512E+01 to avoid contact instabilities.

00 The LS-DYNA time step size should not exceed 1.546E+01 to avoid contact instabilities.

00 The LS-DYNA time step size should not exceed 8.278E+00 to avoid contact instabilities.

= 2 current minimum time step = 3.267E-08 The LS-DYNA time step size should not exceed 3.267E-08 to avoid contact instabilities.

= 2 current minimum time step = 3.267E-08 The LS-DYNA time step size should not exceed 3.267E-08 to avoid contact instabilities.

DCT should be -1 in *CONTROL_ALE *** Warning 10989 (KEY+989) AFAC not equal to -1 in *CONTROL_ALE invokes ALE smoothing which is not supported for MPP versions.

stop ls-dyna terminates. sw1. a restart file is written and ls-dyna terminates. sw2. ls-dyna responds with time and cycle numbers. sw3.

hypermes划分好网格之后导入ansy/lsdyna求解出现无质量节点警告，该怎么解决？ 再删除多余节点是又显示图二nodes were attached to elements，怎么办？
