Frequently Asked Questions
When is FEA required instead of standard code calculations?
FEA is required when:
Geometry is complex
Loading conditions are non-standard
Stress concentrations are critical
Fatigue or thermal effects must be evaluated
It provides far more accurate results than simplified code formulas.
What FEA software do you use?
ANSYS Mechanical for most simulations
Abaqus for advanced non-linear and dynamic problems
All analyses are performed and validated by experienced engineers.
Can FEA be used to assess existing equipment?
Yes. We perform fitness-for-purpose assessments using FEA to evaluate:
Corroded or damaged equipment
Life extension possibilities
Changes in operating conditions
Following standards such as API 579 / ASME FFS-1.
