检查时出现报错：surfaces below have a mixture of 3D shell edges and other types. if a surface has any 3D shell edges then all of its 这要怎么解决呢？

ABAQUS中施加均布荷载时出现如下报错：SURFACE ASSEMBLY_SURF-1 INCLUDES EDGES.

The *tie pair (assembly_surf-26-ouhemian,assembly_surf-19) is also used as *contact pair. Remove this *contact pair.

between surfaces ASSEMBLY_M_SURF-1 and ASSEMBLY_S_SURF-1 is causing a 72.434% reduction in the time increment.

THEY ARE PAIRED WITH MASTER SURFACES ASSEMBLY_CP-1-PART-FDTT1-S-1 AND ASSEMBLY_CP-2-PART-FDTT1-S-1 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.

The contact pair referencing surfaces assembly_m_surf-1 and assembly_s_surf-1 has at least one instance of a node belonging to both surfaces.

THIS MAY BE DUE TO NONEXISTENT SLAVE OR MASTER SURFACE, OR DUE TO ERRORS WHEN PROCESSING THE *CONTACT PAIR KEYWORD我明明定义了slave surface 和 master surface。

THEY ARE PAIRED WITH MASTER SURFACES ASSEMBLY_PICKEDSURF74 AND ASSEMBLY PICKEDSURF77 THAT ALSO INTERSECT EACH OTHER.IF BOTH PAIRS ARE *CONTACT PAIRs, THESE TWO PAIRS SHOULD NOT BE SIMULTANEOUSLY PRESENT

Surface based COHESIVE BEHAVIOR cannot be used for contact pair interactions. See the surface interaction named INTPROP-CO.

Surface assembly__pickedsurf15 has facets that are not oriented properly with respect to neigh boring facets. Use available post processor to visualize surface normals.
