SOLIDWORKS® Flow Simulation is an intuitive Computational Fluid Dynamics (CFD) solution embedded within SOLIDWORKS 3D CAD that enables you to quickly and easily simulate liquid and gas flows through and around your designs to calculate product performance and capabilities. No heat can be exchanged between the two bodies without specifying additional boundary conditions (convection, radiation, etc). No input is required for the J-parallel condition because it is the natural boundary condition. Thermal results show the temperature of the cooling channel is uniformly distributed ( ∆T~35 °C), and the results will coupled into structural analysis. Using symmetry constraints makes your model half the size it would be otherwise, so. The accuracy of the simulation results depends on defining these properly. Boundary node displacements parallel to the boundary faces are coupled through the following relation: δ δi j− =0 (1) where δi and δj are displacements parallel to the boundary face of the boundary nodes i and j.
