The general contact domain for modeling contact interactions in Abaqus/Standard has double-sided facets. Initial contact adjustments for resolving gaps and overclosures when a surface with double-sided facets is paired with any surface having double-sided facets may be incorrect. Similarly, adjustments for double-sided surfaces crossing each other may be incorrect and no additional warnings or error messages will be issued. In all these cases, we recommend using single-sided surfaces under *CONTACT INITIALIZATION ASSIGNMENT to handle initial adjustments more precisely and avoid possible convergence problems.
Abaqus/Standard中用于建模接触交互作用的通用接触域具有双面刻面。当具有双面刻面的表面与具有双面刻面的任何表面配对时，用于解决间隙和过度闭合的初始接触调整可能不正确。同样，对彼此交叉的双面表面的调整可能不正确，不会发出额外的警告或错误消息。在所有这些情况下，我们建议在*CONTACT INITIALIZATION ASSIGNMENT下使用单面曲面，以更精确地处理初始调整并避免可能的收敛问题。
