Exploring the Process of Adaptive Analysis

Adaptive analysis

In adaptive analysis, the final solution is obtained through multi-step mesh refinement and modification adaptively pursuing geometric and computational accuracy.

Executing an adaptive analysis

In order to use this educational function, an adaptive analysis process should actually be executed at least once. You can specify either the number of iteration or the target error of convergence. The user can watch the gradual refinement of the finite element mesh, while the iterations are being repeated. The intermediate analysis results and the mesh can be saved for later observation. Once the process is completed, one of the intermediate stages can be displayed in arbitrary order.

Visualizing the process of adaptive analysis

Shown in the figure below is an example of visualizing progressively the analysis results and the mesh refinement at intermediate stages of adaptive analysis. The user can move quickly to the desired stage of the adaptive process, and examine the error distribution and corresponding mesh refinement. The whole adaptive procedure can also be visualized in the form of animation, by which the gradually changing error distribution and mesh refinement can be observed.
