Modeling Engineer

Overview

Develop and validate advanced finite element models for structural, thermal, and materials analyses.

Key Responsibilities

• constitutive modeling
• umat development
• fea modeling
• hybrid modeling
• structural analysis
• technical documentation

Tasks

-Develop and calibrate constitutive models for metals, polymers, composites, or coatings based on experimental data. Implement custom material subroutines (e.g., UMAT/VUMAT). -Lead the development, validation, and enhancement of high-fidelity finite element models for mechanics analysis and potentially heat conduction analysis. Produce advanced model that capture multi-physics coupling, material nonlinearity, and complex boundary interactions. -Prepare technical documentation, analysis reports, and presentations summarizing modeling work. -Work with design, manufacturing, and product development teams to translate engineering insights into applicable design or process changes. -Collaborate with material scientists to design validation experiments, compare simulation predictions to physical test results, and refine models for improved accuracy and predictive power. -Lead research efforts in model accuracy improvement, numerical stability, and computational efficiency. Explore latest numerical methods (e.g., cohesive zone modeling, phase-field fracture, multi-scale modeling) to expand simulation capabilities. -Data-Driven & Hybrid Modeling: Integrate data analytics, machine learning, and statistical inference techniques with traditional FEA to build hybrid physics–ML models. Develop surrogate models, reduced-order representations, or Gaussian Process regressors to accelerate simulation cycles and support uncertainty quantification. Use experimental databases and simulation data to extract governing relationships, automate parameter calibration, and ensure predictive digital twins. -Develop and guide linear/nonlinear structural, thermal, impact, and fatigue analyses using commercial FEA tools (e.g., ABAQUS, ANSYS, LS-DYNA, COMSOL). Interpret simulation outcomes with scientific rigor to uncover fundamental failure mechanisms, improve design decisions, and establish predictive design guidelines.
