I get the warning No. 469 "Lines lying in the surface [line numbers] intersect and have no common node". If I confirm the warning with "No", error No. 639 "Error No. 11 when generating the FE mesh! ". What should I do?

Answer

The intersection of the lines named in the warning must be created with the function "Connect Lines / Members." To do this, select the Connect Lines / Members function and then draw a window across the elements to be trimmed (see Figure 3).


In many cases, stiffening bracings are modeled in the same plane as the surface, and the members are subsequently set eccentrically. Please keep in mind that the lines and thus also the members are automatically integrated into the surface. As the stiffening brace should normally only transfer axial forces, it is recommended to remove it from the surfaces to avoid creating a bond between surface and member. To do this, you have to remove the corresponding lines from the surface in the "Integrated" tab (see Figure 4).
