There are some mistakes.
Try to correct them by yourself, as in this way you will learn better:
- In OpenSees, 2D models MUST be in the XY plane. You can rotate your model so that it is in the XY plane
- Remove construction lines (otherwise they will generate floating nodes in OpenSees). Also those lines have assigned the quad element property (thus the error you are seeing: quad = 4 nodes, edge = 2 nodes)
- Make sure the free field geometries have the same mesh seed.
Note:
This webinar was quite old.
Now in OpenSees we implemented a new automatic absorbing boundary element which makes the modeling much easier:
