heat transferboundaryconditionbasedontheboundaryelementmethod(BEM)andthetopology
optimization method.Thelevelsetmethodisusedtorepresentthestructuralboundariesandthe

paper isthatthegoverningequationissolvedwithoutersatzmaterialapproachandapproximatedheat
convectionboundaryconditionbyusingthemeshgeneration.Additionally,theobjectivefunctionalis
defined alsoonthedesignboundaries.First,thetopologyoptimizationmethodandthelevelsetmethod
are briefly discussed.Usingthelevelsetbasedboundaryexpression,thetopologyoptimizationproblem
for theheattransferproblemwithheattransferboundaryconditionisformulated.Next,thetopological
