for modeling heat generation due to friction in cutting process we must use couple structural-thermal.

in ANSYS WB, They  are  sequential  coupling  and  direct  coupling .  In  sequential  coupling ( thermal  to  structural or structural to thermal ) , coupling is considered in one direction only  and i thing that couple thermal -structural incorrect if i want simulate  heat generation in cutting process so my questions

1) is coupling (structural to thermal) available in WB ?  

2) use of structural-thermal coupling for modeling cutting process , it's right?  or only exiplicit dynamic- thermal coupling is right.

please help me
