| - | This law is only used for linear thermal analysis of pollutant transport. This constitutive law takes account of transfer between the solid and the external world by convection. The coefficients of convection are constant. Those coefficients induce a mix boundary condition on the diffusive flux. This law is used with element [[elements:conra|CONRA]]. | + | This law is only used for linear thermal analysis of pollutant transport.

| N.B. DXP is the average length of the elements of solid in the velocity direction it is used (as ur, vr, diffm, along) only if upwind is acting and if ICAS≠4 in [[elements:conra|CONRA]] elements. | N.B.
