To qualitatively and quantitatively analyze the stress on the door cover during thermal expansion and contraction, the engineers used HyperMesh, a high-performance finite element pre-processor and RADIOSS, a modern structural analysis and optimization solver, both of which are part of Altair’s HyperWorks suite of computer-aided engineering tools. With these tools, engineers created a computerized simulation of the refrigerator door cover temperature field, employing HyperMesh to create a finely meshed model of the upper and lower covers, while shell elements were used to mesh the steel plate and interior lining, along with solid elements for the foaming material.
