Q1. How validate your model?
Ans. 
To validate a CAE model, various methods can be used such as comparing simulation results with experimental data, conducting sensitivity analyses, and performing model correlation.
• Compare simulation results with experimental data to ensure accuracy

• Conduct sensitivity analyses to assess the impact of input parameters on the model

• Perform model correlation by comparing predicted behavior with real-world observations

• Valida...read more

Q2. How define boundary?
Ans. 
Boundary is the limit or edge of a system or object.
• Boundary defines the extent or scope of something.

• It separates one system or object from another.

• Boundaries can be physical, such as walls or fences, or conceptual, such as rules or regulations.

• In engineering, boundaries are often defined to specify the limits within which a system or component operates.

• For example, in CAE analysis, boundary conditions are set to defi

Q1. What is fea general equation
Ans. 
The FEA general equation is a mathematical representation used in Finite Element Analysis to solve complex engineering problems.
• The FEA general equation relates the stiffness matrix, displacement vector, and force vector in a system of linear equations.

• It is used to simulate the behavior of structures under various loading conditions.

• The equation is typically solved iteratively using numerical methods like the finite e...read more

Q2. What is warpage
Ans. 
Warpage is the deformation or distortion of a material, typically caused by uneven cooling or stress.
• Warpage occurs when different parts of a material cool at different rates, causing uneven shrinkage.

• It can also be caused by internal stresses within the material.

• Warpage is a common issue in plastic injection molding and can lead to dimensional inaccuracies in the final product.

• To prevent warpage, proper cooling and st...read more
