3.5: Frame with Fixed Temperatures

Geometry, Material, and Boundary Conditions

Dimensions: Hollow tubular frame, L=2.25m, H=1.5m, D=1.5m.

Results

Reference results from [16]. After some assumptions about the problem setup, it was determined that the cross sectional area of the tubular frame would not affect the temperature values. Since this is the case, the frame was modeled as a solid object instead of hollow tubes.
