Map transverse temperature gradients to the target solution
A source model refers to a model that contains a solution with Analysis Type set to any thermal or coupled thermal-flow type.
A target model refers to a model that contains a solution with Analysis Type set to Mapping.
Create a transverse gradient zone in the source model
Choose Home tab→Loads and Conditions group→Mapping .
In the Mapping dialog box, from the Type list, select Transverse Gradient Zone.
Select source elements in one of the following ways:For temperature gradient mapping from two parallel 2D meshes to one 2D mesh, in the Top Elements and Bottom Elements groups, select the top and bottom elements between which there is a temperature differential you want to map to the target model.For temperature gradient mapping from one 2D multi-layer shell mesh to one 2D mesh, in the Multi-Layer Elements group, select multi-layer elements.
From the Thickness Option list, select the way in which the thickness of the selection is defined:From Thermal Model defines thickness as the physical distance between the two meshes.Specify defines thickness as the distance you type in the Thickness Value box.
Click OK.
Create a transverse gradient target zone in the target model
Choose Home tab→Loads and Conditions group→Transverse Gradient Target Zone .
To select the elements or nodes to which you want to map the transverse temperature gradient results, in the Transverse Gradient Target Zone dialog box, do the following:In the Destination Model Elements group, select the elements.In the Destination Model Nodes group, select the nodes.
In the Corresponding Source Model Elements group, click Update Zones.
From the Transverse Gradient Association Zone list, select the transverse gradient association zone that you created in the source model.
Click OK.
