I am trying to simulate microstructure modified surface where fluid will flow as well as heat transfer will applied at the bottom of the surface .In this case ,I used Conjugate heat transfer mechanism .but i am getting error :Failed to evaluate operator.
- Operator: mean
- Geometry: 1
- Boundary: 1
Mean operator requires an adjacent entity of higher dimension.
Failed to evaluate expression.
- Expression: mean(comp1.nitf.mu)
Failed to evaluate variable.
- Variable: comp1.nitf.mu
- Geometry: 1
- Boundary: 1
Failed to evaluate expression.
- Expression: d((((-2*comp1.nitf.mu*comp1.uTx+comp1.p)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nxmesh,x)-comp1.nitf.mu*(comp1.uTy+comp1.vTx)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nymesh,x)-comp1.nitf.mu*(comp1.uTz+comp1.wTx)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nzmesh,x)-comp1.nitf.mu*(comp1.uTy+comp1.vTx)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nxmesh,y)+(-2*comp1.nitf.mu*comp1.vTy+comp1.p)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nymesh,y)-comp1.nitf.mu*(comp1.vTz+comp1.wTy)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nzmesh,y)-comp1.nitf.mu*(comp1.uTz+comp1.wTx)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nxmesh,z)-comp1.nitf.mu*(comp1.vTz+comp1.wTy)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nymesh,z)+(-2*comp1.nitf.mu*comp1.wTz+comp1.p)*dtang((test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.nzmesh,z))*comp1.nitf.Lentr-(test(comp1.u)*comp1.nitf.nxmesh+test(comp1.v)*comp1.nitf.nymesh+test(comp1.w)*comp1.nitf.nzmesh)*comp1.nitf.Pinlinl1)*(dvol),{test@24})
