THE SLAVE SURFACES ASSEMBLY_SOIL-3_SURF-1 AND ASSEMBLY_SOIL-3_SURF-2 INTERSECT EACH OTHER. THEY ARE PAIRED WITH MASTER SURFACES ASSEMBLY_PILE-3_SURF-1 AND ASSEMBLY_PILE-3_SURF-2 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.

另外：怎樣在模型樹里顯示警告里所指的從面？，比如：ASSEMBLY_SOIL-3_SURF-1
