Answer 2

A numerical approximate approach (such as FEM or CFD) is usually used to solve complex engineering problems.

The uncertainties associated with such an approach is: Aleatoric and Epitemic.

This is due to the following factors that Finite Element Method (FEM) is applied in order to calulate the flow of the fluid. And Computational Fluid Dynamics (CFD) is used to solve the analytical issues that is related to the flows of the fluid.

The relation between these issues are aleatoric and epistemic.
