Ls dyna求解时，出现以下问题没法求解什么原因呢？ 40

*** Warning 20339 (STR+339)

    nodal contact forces are available only

    for the master side with node to surface

    contact types of interface # 1

*** Warning 20535 (STR+535)

    contact interface # 1

    was switched from SOFT=2 to SOFT=1.

    The segment based contact option is only valid for

    contact types 3, a3, 4, 13, 14, 15, 10, and a10

input of data is completed

initial kinetic energy = 0.00000000E+00

The LS-DYNA time step size should not exceed     2.235E-05

to avoid contact instabilities.  If the step size is

bigger then scale the penalty of the offending surface.

我是用的hypermesh导入ansys再输出k文件求解的。然后就出现这些问题了。
