I applied via Referral and was interviewed before Nov 2023. There was 1 interview round.

Round 1 - Technical 

(4 Questions)

  • Q1. How to measure convergence?
  • Ans. 

    Convergence in CFD analysis is measured by checking if the solution is not changing significantly with each iteration.

    • Convergence is typically measured by monitoring residuals of key variables (e.g. velocity, pressure) over iterations. When residuals reach a small, acceptable value, convergence is achieved.

    • Another method is to track the change in key parameters (e.g. mass flow rate, drag coefficient) between iterations...

  • Q2. Experience with PowerFlow and ANSYS
  • Ans. 

    Experience with PowerFlow and ANSYS

    • I have extensive experience using PowerFlow for fluid dynamics simulations

    • I am proficient in using ANSYS for structural analysis and thermal simulations

    • I have successfully integrated PowerFlow and ANSYS for multiphysics simulations

    • I have worked on projects where accurate CFD analysis was crucial for design optimization

  • Answered by AI
  • Q3. What is CFL number?
  • Ans. 

    CFL number is a dimensionless number used in fluid dynamics to determine the stability of a numerical simulation.

    • CFL number stands for Courant-Friedrichs-Lewy number.

    • It is calculated as the product of the flow velocity, time step, and grid spacing, divided by the fluid kinematic viscosity.

    • A CFL number greater than 1 indicates that the simulation is unstable and may lead to inaccurate results.

    • A CFL number less than 1 en

  • Answered by AI
  • Q4. What is difference between RAN, LES and DNS
  • Ans. 

    RAN, LES, and DNS are different approaches used in computational fluid dynamics (CFD) to model turbulent flows.

    • RAN (Reynolds-Averaged Navier-Stokes) models average the flow properties over time, suitable for industrial applications.

    • LES (Large Eddy Simulation) resolves large turbulent structures while modeling smaller ones, suitable for complex flows.

    • DNS (Direct Numerical Simulation) solves all scales of turbulence with...

(2 Questions)

  • Q1. What is understeer gradient?
  • Ans. 

    Understeer gradient is the rate at which the steering angle changes in response to a change in lateral acceleration.

    • Understeer gradient is a measure of how much the front tires lose grip and slip angle as the vehicle turns.

    • A higher understeer gradient means the vehicle will have less responsive steering and may require more steering input to navigate corners.

    • Understeer gradient can be influenced by factors such as tire...

  • Q2. Differences of choice of Mcstrut and double wishbone
  • Ans. 

    Mcstrut and double wishbone are two different types of suspension systems used in vehicles, each with its own advantages and disadvantages.

    • Mcstrut suspension is simpler and more cost-effective, but may not offer as much performance as double wishbone.

    • Double wishbone suspension provides better handling and stability, but is more complex and expensive to manufacture.

    • Mcstrut suspension is commonly used in front-wheel driv...

Round 1 - Technical 

(1 Question)

  • Q1. What is the difference between True & engineering stress ? How to derive true stress using engineering stress - strain curve ? Why quad element is preferred over Tria, element formulation of quad & tria? W...
  • Ans. 

    Answers to questions related to stress and strain in engineering

    • True stress considers the change in area due to deformation, while engineering stress does not

    • True stress can be derived from engineering stress using the formula: true stress = engineering stress * (1 + engineering strain)

    • Quad elements are preferred over tria elements because they provide better accuracy and convergence

    • Plane stress is a condition where st...
