Sample interview questions: How do you handle uncertainties and errors in your computational models?

Sample answer:

In computational physics, handling uncertainties and errors in computational models is of utmost importance to ensure accurate and reliable results. As a computational physicist, I employ several strategies to address uncertainties and errors in my models.

First and foremost, I implement robust numerical techniques that are known for their stability and accuracy. This includes using higher-order numerical methods that minimize truncation errors and ensure efficient convergence. By selecting appropriate numerical algorithms and discretization schemes, I can significantly reduce the introduction of errors in my computational models.

To further mitigate uncertainties, I perform extensive validation and verification of my models. This involves comparing the results obtained from the computational model with analytical solutions or experimental data whenever possible. By conducting these comparisons, I can identify any discrepancies or inconsistencies, allowing me to refine and improve the model accordingly.

Uncertainties can also arise from the input parameters used in the simulations. To account for this, I conduct sensitivity analyses to determine how variations in these parameters affect the model’s output. By identifying the most influential parameters, I can focus on obtaining precise measurements or reducing their uncertainties through experimental or theoretical means. Additionally, I utilize statistical techniques such as Monte Carlo simulations to explore the impact of parameter uncertainties on the overall model predictions.

When it comes to handling errors, I implement comprehensive error analysis methodologies. This involves quantifying the errors and uncertainties associated with the computational model and its results. I take into account various sources of errors, including numerical, statistical, and modeling errors. By estimatin… Read full answer
