Hexdof Engineering Services CAE Engineer Interview Questions, Process, and Tips

Degree of Freedom refers to the number of independent parameters required to define the position or configuration of a system.

• It is a measure of the number of ways a system can move or change.

• In engineering, it is used to describe the number of independent variables that can be changed to alter the behavior of a system.

• For example, a rigid body in three-dimensional space has six degrees of freedom: three for translatio...read more

Hypermesh tools & shortcuts are used for meshing and pre-processing tasks in CAE. They help in saving time and improving efficiency.

Shell meshing is a technique used in Hypermesh to create a mesh of thin-walled structures.

• Shell meshing is used for structures that have a thickness much smaller than their other dimensions.

• It involves creating a mesh of the mid-surface of the structure and then extruding it to create a 3D mesh.

• Shell meshing is commonly used in the aerospace and automotive industries for components such as panels and shells.

• It can help...read more

I have worked on various components including engine blocks, suspension systems, and body structures.

• Collaborated with cross-functional teams to integrate components i

Hypermesh quality criteria and definitions

• Hypermesh quality criteria are used to ensure the accuracy and reliability of finite element models

• Some of the criteria include element quality, mesh density, and mesh size

• Element quality refers to the shape and distortion of individual elements

• Mesh density refers to the number of elements in a given area

• Mesh size refers to the size of individual elements

• Hypermesh also provides
