In simulating heat transfer through a pipe with convection boundary conditions on the inside and out, I used the field function
($$Position(@CoordinateSystem("Laboratory.Cylindri cal"))[0]<0.3)?55:0.04 to define a thermal conductivity of 55 W/m-K when the radius is <0.3 (for the pipe) and 0.04 W/m-K for radius>0.3 (for the insulation). However, I get the error message "Field function "Variable Conductivity" cannot be evaluated on region Pipe solid" when assigning this field function to the Thermal Conductivity material property. Any suggestions? |
