Abaqus - Generating output result, correct connections and mesh quality

Hello everyone, I am facing the issue with generating output results. Can someone tell me the detailed information about the conditions and methods for getting output result. 

Also, the design on which i am doing analysis consists of about 200 bodies. so, how to give correct connections (contact between two bodies) or how to check the automatically generated contacts, as it is very time consuming can someone suggest the ways to reduce time for each iteration.

And how we can check mesh quality or how we can improve it in SIMULIA.
