登錄*model change, type= element, removePART-1-1.SET-0** STEP: Step-2** *Step, name=Step-2, nlgeom=NO*Static1., 1., 1e-05, 1.*model change, type= element, ADDPART-1-1.SET-0


如果兩對都是*接觸對,則這兩對不應在一個步驟中同時存在,因為可能存在收斂問題;使用*MODEL CHANGE,TYPE=觸點對移除其中一個。如果兩者都是*扎帶對,多余的扎帶將自動移除。如果一對是領帶,另一對是接觸線,請取下其中一對。





These constraints are not removed either due to the presence of *CONSTRAINT CONTROLS,NO CHANGES keyword or because removing the constraints might affect the model.

In step 1, element 879 instance soil-2 cannot be added using *model change because it is not currently removed.

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.
*model change is not permitted in a perturbation step這個需要怎么改一下
