This subject introduces the student to the various forms of engineering simulation, which can be used in conjunction with 3D modelling tools. It illustrates the importance of testing and analysing at the design stage. It demonstrates, by example, software tools which can be used alone or as part of a suite in order to solve at the design stage, problems, which may occur during a downstream operation.
Finite Element Analysis:
- Meshing and Element types: 1D, Truss, Beam, Axisymmetric, 2D, Plate, Mid Plane, Solid (Bricks, Quadrilaterals, Tetrahedral)
- Boundary Conditions; Restraints, Forces, Displacements etc.
- Mesh refinement & Convergence
- Output Types and Interpretation; Von Mises stress, Displacement,
- Material Models
- Analyses types; Linear Static, Non-Linear & Dynamic, Thermal (Steady state analysis & Transient analysis)
Fluid Flow:
- Analyse the flow of gases and fluids over various structures
Mould flow analysis:
- Analysis of material flow in a mould cavity
- Defect identification (Weld lines, Sink marks, Flow patterns etc.)
- Process parameters (Minimum wall thickness, Cycle times, Materials, Injection points, Pressure & Dwell)
Optimisation and Generative Analysis:
- Generation of design concepts using Topology Optimisation and Generative design tools
