How can I change the spacing between the dividing lines of sections?
The spacing in my model is too big.
The spacing of the division lines for the sections displayed in the graphic is determined by the length of the finite elements.
The corresponding global settings are defined by selecting "FE Mesh Settings" on the "Calculate" menu in the toolbar. If you want to define settings for portions only, go to the "Insert" menu and select "Model Data" and "FE Mesh Refinements". The division spacing in the sections changes when you change the target length of the finite elements.
