If there is no mesh refinement defined, the global mesh settings apply to the model. However, you can use the mesh refinements for the important areas in order to keep the low number of finite elements and thus the short computing time. The important areas are either important for the evaluation or affect the accuracy of modelling:
- Member-surface transitions
- Wall ends (see the figure)
- Division of members for a dynamic calculation (otherwise it is not enough or no mode shapes are found)
It is recommended to perform the analysis of FE mesh quality on a model in order to examine the impact of the FE mesh size on the result. Thus, you can find the optimum between the required accuracy and the computing time.
