Reliance Communications Interview Questions and Answers

Views in a CAD drawing are different perspectives of the same object or assembly.

• Views show different angles, sections, or details of the design

• They help in visualizing the design and checking for errors

• Common views include front, top, side, isometric, and section views

• Views can be annotated with dimensions, notes, and symbols

• Examples of CAD software that support views are SolidWorks, AutoCAD, and CATIA

Turbulence models are used to predict the behavior of turbulent flows by simulating the effects of eddies and vortices.

• Turbulence models are based on the Navier-Stokes equations, which describe the motion of fluids.

• They use statistical methods to simulate the effects of turbulence on the flow.

• There are two main types of turbulence models: Reynolds-averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES).

• RANS models average the turbulent flow over time, while LES models s...read more

Steady solver solves for a steady-state solution while transient solver solves for a time-dependent solution.

• Steady solver assumes that the solution does not change with time while transient solver considers the time-dependent behavior of the solution.

• Steady solver is faster and less computationally expensive than transient solver.

• Transient solver is required for problems that involve time-varying boundary conditions or fluid flow behavior.

• Examples of steady solver include Po...read more

Mesh independent study is a process of verifying the accuracy of simulation results by varying the mesh size.

• It involves running simulations with different mesh sizes

• The results are compared to determine if they converge to a consistent solution

• It helps to ensure that the simulation results are not dependent on the mesh size

• It is important for accurate and reliable CFD simulations

• Example: A CFD analyst may perform a mesh independent study on a wing to determine the optimal me...read more
