What is the need of order change in hypermesh?

In Hypermesh, "order change" refers to the process of altering the element type or order within a finite element mesh. This can involve changing from lower-order (linear) elements to higher-order (quadratic) elements, or vice versa. As an experienced tutor registered on UrbanPro.com, I can explain the need for order change in Hypermesh:

1. Improved Accuracy:

   • Order change allows for higher-order elements, which can provide more accurate results, especially in regions with high gradients of stress, strain, or other physical quantities. This is crucial for accurate finite element analysis (FEA).

2. Efficient Meshing:

   • Depending on the geometry and loading conditions, it may be more efficient to use lower-order elements in certain areas of the model and higher-order elements in others. Order change facilitates this mesh optimization.

3. Balancing Computational Cost:

   • Higher-order elements require more computational resources compared to lower-order elements. By strategically implementing order changes, engineers can balance accuracy with computational efficiency.

4. Convergence and Solution Stability:

   • In some cases, using higher-order elements can improve the convergence behavior and stability of the solution, particularly in simulations with complex geometry or loading conditions.

5. Reducing Element Count:

   • In certain situations, using higher-order elements can lead to a reduction in the total number of elements required to achieve a desired level of accuracy. This can lead to faster solution times.

6. Mesh Transition:

   • Order change is useful when transitioning between different mesh regions with varying degrees of detail. For example, a finer mesh may be needed in regions of high stress concentration.

7. Compatibility with Solvers:

   • Some solvers may have specific requirements for element types and orders. Order change allows engineers to meet these requirements while maintaining a consistent mesh.

8. Accommodating Analysis Needs:

   • Different types of analysis (static, dynamic, thermal, etc.) may have specific requirements for element order. Order change enables engineers to adapt the mesh to meet these analysis needs.
