abaqus中.sta文件这些关于接触的话什么意思呀，看的模模糊糊不是太理解？

INFORMATION REGARDING INITIAL CONTACT PAIR OVERCLOSURES THAT Abaqus/Explicit

  WILL ATTEMPT TO RESOLVE WITH STRAIN-FREE ADJUSTMENTS TO POSITIONS OF

  DEFORMABLE

  SLAVE NODES Step   1

  -----------------------------------------------------------------------------

  ---

  Maximum overclosure between surface ASSEMBLY_SURF-PIN and surface

  ASSEMBLY_SURF-DISC is 1.62371E-02.

Maximum adjustment for initial overclosure is: 1.62371E-02 at node 12 of instance XINPIN_R80.

***NOTE: You can view the deformed configuration due to the resolution of

         initial overclosures.  In increment 0, draw the deformed shape or

         draw a symbol plot of vector displacements.

More detailed overclosure adjustment information can be found in the message file.

  INFORMATION REGARDING UNRESOLVED INITIAL CONTACT PAIR OVERCLOSURES FOR

  SLAVE NODES Step   1

-----------------------------------------------------------------------------

  ---

***WARNING: For contact pairs that are not tied, unresolved initial

            overclosures will result in initial accelerations on the order of

            the penetration distance divided by the time increment squared,

            which can lead to significant mesh distortion. These overclosures

            can be avoided by user adjustment of the mesh.

  Maximum overclosure between surface ASSEMBLY_SURF-PIN and surface

  ASSEMBLY_SURF-DISC is 2.87868E-19.
