Depends greatly on your sim, and how much the customer wanted to 'tune' the malfunction. In general however, the engine separation malf
should feed into the mass proerties model. Other system effects will depend on where the break in the pylon is modeled - up/down stream of the fuel LP shutoff valves for example. On one I looked at recently, when the engine came off the wing we put a high fuel flow demand into the fuel system for that engine position. However, getting hard data for engine separation effects from the OEMs is like getting hold of hen's teeth.
