我做了一個(gè)落錘沖擊梁的模型，落錘用的離散剛體，加工成殼，用動(dòng)力隱式可以計(jì)算，但用動(dòng)力顯式就報(bào)錯(cuò)。

動(dòng)力隱式容易不收斂，所以現(xiàn)在不知道在顯式中怎么改。

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.
