What to Expect in a CAE Engineer Interview | Engineer’s Interview Blueprint

Introduction 

Preparing for a CAE Engineer interview can be a daunting task.  

You’ve probably already perfected your CAE Engineer resume, but are you fully prepared for the interview itself? 

The challenges don’t stop at mastering complex tools like FEA or ANSYS—they extend to navigating real-world problems under pressure. 

You’ve spent years honing your skills, but when the moment comes, you may find yourself wondering: What will they ask me? How can I prove I’m the right fit for the role?  

In this blog, we’ve gathered actual CAE Engineer interview questions asked by Xitadel to give you an edge.  

You’ll not only review technical questions but also gain insight into what employers are truly looking for.  

These real-time CAE Engineer interview questions and answers will help you focus your preparation, enabling you to face even the trickiest challenges with confidence. 

Let’s get started.

1. What is CAE, and why do we need CAE? 

CAE (Computer-Aided Engineering) involves using computer software to simulate performance and behavior of products under different conditions. It helps in optimizing designs, reducing the need for physical prototypes, and improving product performance while cutting down development costs. 

2. What are the Quality Criteria? 

Quality criteria are standards set for mesh quality in FEA (Finite Element Analysis). These include parameters like skewness, aspect ratio, and warpage, which ensure that the mesh elements are well-formed and the analysis results are accurate. 

3. What quality criteria values did you use for different meshing?

Different types of meshing require varying quality standards. For instance: 

• For 2D meshing, the aspect ratio should ideally be close to 1. 

• For 3D meshing, the skewness should be below 0.85 for accurate results. These values help ensure mesh consistency and reliable simulation results. 

4. Can you explain skewness, warpage, and Jacobian? 

• Skewness: Measures how far an element deviates from its ideal shape. Lower skewness values indicate better quality. 

• Warpage: Refers to the bending or twisting of an element’s surface. Minimal warpage ensures better structural integrity in the mesh. 

• Jacobian: Checks the accuracy of mesh element transformation. A high Jacobian ratio can indicate poor mesh quality. 

5. What is stress and strain? 

• Stress is the force applied per unit area of a material. 

• Strain is the deformation that occurs in a material due to applied stress. 

6. What is the significance of FEA? 

FEA (Finite Element Analysis) helps in predicting how a product reacts to real-world forces, vibration, heat, and other physical effects. It's significant because it enables engineers to optimize designs and identify potential failure points before manufacturing. 

7. What is Warpage? 

Warpage refers to the distortion or deviation of an element’s surface from its ideal flat shape. It occurs when different parts of the element experience uneven deformation during meshing, which can lead to inaccurate simulation results. 

8. What is the ideal aspect ratio? 

The ideal aspect ratio of a mesh element should be 1:1, which means the length and width are equal. However, in practice, for 2D elements, an aspect ratio between 1:1 and 1:5 is often acceptable. 

9. What are some of the projects you've done? 

This is your opportunity to describe any design or simulation projects you've worked on. Highlight projects that involved CAE, FEA, or meshing, and explain how you approached the problem and what results you achieved. 

10. What are the types of mesh? 

• 1D mesh: Used for beam or bar elements in simple linear problems. 

• 2D mesh: Used for shell elements where thickness is negligible compared to other dimensions. 

• 3D mesh: Used for solid elements where all three dimensions are significant. 

11. How do you assign thickness in ANSA? 

In ANSA, thickness can be assigned in two ways: 

• Automatically using the mid-surface extraction tool for sheet metal components. 

• Manually by specifying a thickness value in the properties for elements like shell or plate models. 

12. At what parameter do you decide to use 2D or 3D meshing? 

The decision to use 2D or 3D meshing depends on the geometry and the nature of the analysis. For components with thin walls where thickness isn’t a critical factor, 2D meshing is ideal. However, if all three dimensions are significant, especially for volumetric analysis, 3D meshing is more appropriate.
