How to exactly get the number of initially touching contactor nodes

Hallo, everyone, I am new here, and will be glad to get your help, and also to help others(if i can).

 

Now i am performing an analysis, there are two solid bodies, with flat contact surfaces, the surfaces have exactly same mesh, but why in xxx.f06 file, it said: 

 

Contact group          1 has      243 initially touching contactor nodes

 

the number 243 is much smaller than the number of initially contacted nodes in my model.

 

 

how to make the solver find the exactly number of initially touching contactor nodes (using contact)?
