从find_contacts()函数的原型可知，该函数的使用是非常灵活的。可以不提供任何参数，也可以只提供部分参数。完全不提供任何参数时，所建立的部分接触对的主从面或者类型（contact或tie）可能需要更改，这和ABAQUS CAE中的通用接触的界面操作情况是一样的。当提供参数时，所建立的接触对通常不需要修改了。部分具体使用形式如下所示：
## Interactions
## find_contacts('tie',slave_parts=beam2,master_parts=beam1)
## find_contacts('tie',slave_parts=[beam3,beam4],master_parts=beam2,method='cross')
## find_contacts('tie',slave_parts=sup,master_parts=beam2,method='sets')
## find_contacts('tie',slave_parts=sup,master_parts=panel,baseOn='master')
## find_contacts('tie',slave_parts=sup,master_parts=panel,method='cross')
## find_contacts('tie',slave_parts=sup,master_parts=panel,slave_set='fc_sup_top',master_set='fc_panel_rail_left')
## find_contacts('tie',slave_parts=sup,master_parts=panel,slave_set='fc_sup_top', method='find',byseed='no')
## find_contacts('tie',slave_set='fc_sup_top',master_set='fc_panel_rail_left') ##只提供face set
##
## find_contacts('tie',slave_parts=[rope1,rope2,rope3,rope4],master_parts=beam1,method='cross')
## find_contacts('contact',slave_parts=beam2,master_parts = con2)
find_contacts() ##完全不提供任何参数。
下面在参数全部缺省的情况下的让find_contacts()函数自动查找和建立接触对。该函数还可以通过检查 防止建立重复的接触对。该函数对每一个接触对的主从面均建立face set以便检查接触对的实际接触面积。部分查找过程的输出信息如下：
>>> find_contacts()
...
Finding mate faces of panel_A6 by its setname= fc_panel_rail_right (method=['sets', 'find'], byseed=no, one_one=no)...
