** WARNING 702150 ** Cooling channel element %7d has no roughness value specified, the default value will be used instead
The cooling channel elements require a specified surface roughness in order to calculate the friction losses for the coolant flow in the cooling channels. No values are specified for these elements so the default value will be used.
If you want to use specific channel roughness values, right-click the channel elements, select Properties, and then enter the required Channel roughness value. Ensure also that the defaults .udm file is the data area and rerun the analysis if required.
