On one hand, you can customize the settings globally in RFEM using the "FE Mesh Settings" window, as usual. On the other hand, you can specify the FE mesh size in the "Details of Composition" window in the RF‑GLASS module.
These specifications will be considered as FE mesh refinement in the model and therefore handled with high priority. We generally recommend not using any nodal or line mesh refinements, as they cannot be applied to solids and are, therefore, not taken into account.
