How can you achieve a pure compression connection between two surfaces so that one wall is similar to another?

Answer

Such a connection can be created with a line release. Figure 1 shows an example model where wall 1 should transfer only compressive forces to wall 2.

First, the dialog box for creating a line release needs to be opened (Figure 2). In the dialog box (Figure 3), you can now select the lines for release and the type. The type must also be created. The coordinate system of the line specifies the direction so that the release "If vy positive" must be selected (Figure 4). 

Figure 5 and 6 show in two load cases, how the line release works.
