桩土分析-接触

changanqiangel

THE SLAVE SURFACES ASSEMBLY_S_SURF-1 AND ASSEMBLY_S_SURF-7 INTERSECT EACH OTHER. THEY ARE PAIRED WITH MASTER SURFACES ASSEMBLY_M_SURF-1 AND ASSEMBLY_M_SURF-7 THAT ALSO INTERSECT EACH OTHER. IF BOTH PAIRS ARE *CONTACT PAIRs, THESE TWO PAIRS SHOULD NOT BE SIMULTANEOUSLY PRESENT IN A STEP BECAUSE OF POSSIBLE CONVERGENCE PROBLEMS; USE *MODEL CHANGE,TYPE=CONTACT PAIR TO REMOVE ONE OF THEM. IF BOTH ARE *TIE PAIRS, THE REDUNDANT TIES WILL BE REMOVED AUTOMATICALLY. IF ONE PAIR IS *TIE AND ANOTHER IS *CONTACT PAIR, REMOVE ONE OF THEM
请问有知道这个警告怎么解决的吗？在做桩土地震分析的时候，桩穿过两层不同的土层，分别设置了不同摩擦系数的面面接触，出现这个警告导致计算不收敛。希望路过的大神能帮忙解决一下，感谢！

两层土之间的分界线被赋予了两种接触属性，他的建议是将这两个接触放置在不同分析步中，但只是警告信息，不收敛不一定是这个原因，我的模型也出现了这个警告，但最终收敛。
