When generating surfaces from a member, an instability is displayed during the calculation. Why?


If you generate surfaces from a member, it is necessary to subsequently connect the newly created surfaces with the existing members. For this, you can use a rigid surface (the "Create Frontal Plates on Both Edges" option under Settings, see the figure and the video), for example.
