Computer simulation supporting function - one encouraging proper behaviour (4,5)
I believe the answer is:
role model
'one encouraging proper behaviour' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'computer simulation supporting function' is the wordplay.
I cannot quite understand how this works, but
'simulation' could be 'model' (synonyms) and 'model' is found within the answer.
'function' could be 'role' (synonyms) and 'role' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for role model that I've seen before include "exemplary type" , "A worthy person" , "good person" , "One whose example should be followed" , "One imitated by others" .)
