2. MODELING

CHAPTER 2 "MODELLING" 65 ❖ By right-clicking on the grid, a command menu appears from which Hide can be done - Isolation of the sub-surface mesh before creating the mathematical model. Capability particularly useful when defining the outer boundary for 3D surfaces, for easier identification of sub-surfaces ❖ It is now possible to select multiple subgroups in the surface meshes with Ctrl and with Shift ❖ Automatic deletion of problematic elements (coincident nodes or nodes that are identical) of the finite surface elements is performed ❖ The local axes are now appearing even before the creation of mathematical model and are activated through the "Appearance">> section "Switches" >> "Local Axes". ❖ By using the "Change Face" button the local axes are changed. The above command changes the direction of the surface total.
