abaqus显式接触厚度问题

我做了一个落锤冲击梁的模型，落锤用的离散刚体，加工成壳，用动力隐式可以计算，但用动力显式就报错。

动力隐式容易不收敛，所以现在不知道在显式中怎么改。

For two-dimensional models, if a non-unity thickness is specified for two-dimensional solid elements and these elements are involved in an interaction such as contact, the same thickness should be specified for the out-of-plane thickness of the corresponding surface under *surface interaction.
