Hi ,

I am modelling a 3D geometry consisting of a u-pipe with water flowing in surrounded by a cylinder of soil and have coupled heat transfer with conduction and convection, I got the warning says: inverted mesh near coordinates so I added the moving mesh application and set it at free displacement but I still cant solve it and get this error:
Failed to evaluate expression
- Expression: d((if((gmg_level>-2),0,((((-Txx)-Tyy)-Tzz)*nojac(kmean_T_cc)))+(((Tx*nojac(((u_T_cc-xt)*(C_T_cc*rho_T_cc))))+(nojac(((C_T_cc*rho_T_cc)*(v_T_cc-yt)))*Ty))+(Tz*nojac(((C_T_cc*rho_T_cc)*(w_T_cc-zt)))))),Ty)

Failed to evaluate expression
- Expression: nojac(((C_T_cc*rho_T_cc)*(v_T_cc-yt)))

any one can help me with this error???

Regards
