The program says “Stiffness type is not appropriate to FE type”
1. which FE is correct in this case?
2. on the tab stiffness and materials/stiffness for plate/type of reinforcement there is a button “bar reinforcement (physical equivalent of grid)” it is required to set Hy and Hx. If I have grid with diameter of 12mm and step 200mm along x and y axis. Which values do I need to specify for Hy and Hx?
