abaqus如何实现同一接触对在不同分析步采用不同的接触属性？ 1000

如题，假设A面和B面形成接触对AB，AB接触对在step1里采用属性int1，在step里采用属性int2；通过在相互作用里定义，step1里定义采用int1属性，并在step2里取消激活；step2里定义采用int2；求解时发出警告：The slave surfaces, assembly_s_surf-42 and assembly_s_surf-46 intersect each other and are paired with master surfaces that intersect each other as well. If heat flow occurs and pairs are tied, the common nodes on the slave surfaces may not transfer heat properly due to overconstraints. A remedy is to merge the surfaces as much as possible. The next warning with the same surface names may not be applicable for non-tied pairs in uncoulpled heat transfer analysis.指出从面相交；实际从面assembly_s_surf-42 and assembly_s_surf-46 都是B面。请问有什么办法能实现同一接触对在不同分析步中可以采用不同的接触属性。（主要是想模拟瞬态传热的温升分析heat-transfer分析步）还望路过的大佬不吝指教！先行感谢啦~~
