Computer Aided Engineering (ME-603 (B)) - Important Questions

  1. Unit 47 Marks High Priority

    Explain three-dimensional meshing strategies for solid models using only 3 DOF elements. Discuss common element types used (tetrahedral, hexahedral, wedge, pyramid), their formulation differences, advantages and limitations, and guidelines for choosing element type for complex geometry.

    Core topic from Unit 4; highest frequency in analytics heatmap (Three-dimensional meshing).

  2. Unit 47 Marks Low Priority

    Describe post-processing techniques in finite element analysis. Explain how to interpret contour plots, path/line plots, principal stresses, von Mises stress, nodal reaction forces, and how to perform result checks such as energy balance and convergence of derived quantities.

    Core topic from Unit 4; appears in analytics heatmap (Post-processing techniques).

  3. Unit 47 Marks Low Priority

    Explain special element modelling techniques for joints and fasteners: modelling bolt pretension, contact and friction for bolted joints, use of connector/spring elements, and approaches to model welds (tie, seam weld, solid weld) in structural FEA.

    Core topic from Unit 4; appears in analytics heatmap (Special elements and techniques).

  4. Unit 47 Marks Medium Priority Asked: 2024

  5. Unit 47 Marks Medium Priority Asked: 2024

    A Pelton wheel is to be designed for a head of $200\ \mathrm{m}$ when running at $200\ \mathrm{r.p.m.}$. The Pelton wheel develops $45\ \mathrm{kW}$ shaft power. The velocity of the bucket is $0.4$ times the velocity of the jet, overall efficiency is $0.85$ and coefficient of velocity at nozzle is equal to $0.98$. Find diameter of jet, diameter of runner and speed of nozzle.
