Mesh Controls / Global Seeds
For this analysis I used Hex as Element Shape with a sweep technique in order to get the best mesh finish.
I changed from 1 to 0.15 of approximate global size to get the different number of elements that I used in the mesh convergence analysis.

Global Size: 1 – Elements: 60

Max. Stress and Loc.

Global Size: 0.5 – Elements: 3840

15% Displacement
Global Size: 0.3 – Elements: 28556
Mesh Convergence on 15% displacement analysis.
For this analysis we need to determine a displacement of
15% in the initial height for a cylinder.

Results
As we can see in the mesh sensitivity study, with more elements we get better results but we increase the computational time so we don’t need too much elements for this analysis According to Fourier´s Law, the heat flux is from highest to lowest temperature; therefore, our analysis is correct.

Oven Thermal Analysis
Normal Stress vs Normal Strain
Thermal Analysis
For better results I used the Partition toolset to divide parts or independent part instances into smaller regions. With this we: Gained more control over mesh generation. Obtained regions to which you can assign different element types.

Classical methods They offer a high degree of insight, but the problems are difficult or impossible to solve for anything but simple geometries and loadings. B. Numerical methods (I) Energy: Minimize an expression for the potential energy of the structure over the whole domain. (II) Boundary element: Approximates functions satisfying the governing differential equations not the boundary conditions. (III) Finite difference: Replaces governing differential equations and boundary conditions with algebraic finite difference equations. (IV) Finite element: Approximates the behavior of an irregular, continuous structure under general loadings and constraints with an assembly of discrete elements. 2. Finite Element Method (1) Definition FEM is a numerical method for solving a system of governing equations over the domain of a continuous physical system, which is discretized into simple geometric shapes called finite element.
