This node defines the rectangular block domains of a Battery Layers feature with a Flat-sided oval (prismatic) layer configuration. Select the rectangular block domains located between the semicylindrical domains, which together form a jellyroll geometry. The Through-layer direction option can be aligned with the x-, y-, or z-axis of the default global Cartesian coordinates (x, y, z), to specify the anisotropic thermal conductivity tensor of the battery layers in the selected domains. See the Battery Layers for more details.
