GGU-SLAB: Step 1: Change the subgrade reaction modulus (Example 2)

Go to the "Subgrade/In section" menu item and activate the "Display subgrade reaction" check box. Encompass the entire system with the quadrilateral, ensuring that all nodes are within.

Enter 1000 for the subgrade reaction modulus and confirm with "OK". All nodes have now been assigned this subgrade reaction modulus. This could also have been done (and perhaps even easier) using the menu item "Subgrade/Default subgrade" and then the "For all" Button.
