I applied via Naukri.com and was interviewed in Nov 2021. There were 3 interview rounds.
Non-linearity convergence issue can be resolved by adjusting the solver settings and/or modifying the model.
Check the initial conditions and boundary conditions
Try using a different solver or adjusting the solver settings
Modify the model to reduce non-linearity
Check for any errors in the input data or model setup
Increase the number of iterations or decrease the convergence tolerance
Consider using sub-stepping or adapti...
Ansys APDL has various types of elements including structural, thermal, fluid, electromagnetic, and acoustic elements.
Structural elements include beam, shell, and solid elements
Thermal elements include conduction, convection, and radiation elements
Fluid elements include 1D, 2D, and 3D elements for incompressible and compressible flows
Electromagnetic elements include magnetic, electric, and coupled field elements
Acousti...
Solid elements have 3 degrees of freedom (DOF) because they can only deform in 3 directions.
Solid elements are used to model objects that are not easily deformed in all directions
The 3 DOF are translations in x, y, and z directions
Examples include beams, columns, and plates

Quality checks for mesh include element size, aspect ratio, skewness, orthogonality, and boundary conformity.
Element size should be appropriate for the geometry and physics of the problem.
Aspect ratio should be within acceptable limits to avoid distorted elements.
Skewness should be minimized to avoid numerical errors.
Orthogonality should be maintained to ensure accurate results.
Boundary conformity should be checked to ...

I applied via Approached by Company and was interviewed before Apr 2021. There were 3 interview rounds.
Low cycle fatigue occurs at high stress levels and a small number of cycles, while high cycle fatigue occurs at low stress levels and a large number of cycles.
Low cycle fatigue is caused by plastic deformation and occurs at stress levels above the yield strength of the material.
High cycle fatigue is caused by cyclic loading and occurs at stress levels below the yield strength of the material.
Low cycle fatigue is typica...

I applied via Approached by Company and was interviewed before Apr 2021. There were 2 interview rounds.
Principal stress is the maximum or minimum normal stress acting on a plane at a point in a stressed body.
Principal stress is a type of normal stress.
It occurs on a plane where the shear stress is zero.
The maximum and minimum principal stresses are perpendicular to each other.
The principal stresses are important in determining the failure of a material.
Examples of applications include designing structures and analyzing

I applied via Naukri.com and was interviewed before Jul 2020. There was 1 interview round.
Name mangling is a technique used by compilers to give unique names to functions and variables to avoid naming conflicts.
Name mangling is used in C++ to support function overloading.
It is also used in Python to avoid naming conflicts in modules.
Name mangling can make it difficult to access variables and functions from outside the class in which they are defined.
In C++, name mangling can be seen by using the 'nm' comman
I applied via Naukri.com and was interviewed in Aug 2020. There were 3 interview rounds.
Abstract Factory is a creational design pattern that provides an interface for creating families of related objects.
Abstract Factory is used when we need to create families of related objects without specifying their concrete classes.
It provides an interface for creating objects of related classes without specifying their concrete classes.
It encapsulates a group of factories that have a common theme.
It promotes loose c...
Range based map iteration can be done using a for-each loop or iterators.
Use a for-each loop to iterate over the map elements.
Alternatively, use iterators to traverse the map.
The range-based for loop is preferred for its simplicity and readability.
Example: for(auto const& [key, value] : myMap) { //do something with key and value }
Detached threads are independent threads that run separately from the main thread. Joined threads are threads that wait for the main thread to finish.
Detached threads are created using pthread_detach() function
Joined threads are created using pthread_join() function
Detached threads do not need to be explicitly terminated
Joined threads must be explicitly terminated using pthread_exit() or return statement
Detached thread...
Static code analysis tools are software programs that analyze source code to find potential issues and improve code quality.
Static code analysis tools scan code without executing it
They can detect issues such as security vulnerabilities, coding errors, and performance problems
Examples of static code analysis tools include SonarQube, ESLint, and Checkstyle
Command to list currently running threads in linux
Use the 'ps' command with the 'H' option to display threads in a hierarchy
Use the 'top' command to display threads in real-time
Use the 'htop' command for an interactive display of threads
No, arithmetic operations cannot be performed on unique pointers.
Unique pointers are used to manage the lifetime of dynamically allocated objects.
They cannot be copied or assigned, only moved.
Arithmetic operations are not defined for pointers, including unique pointers.
