How can I interpret and correct tolerance problems that occur when generating the bar model?

FE meshes are generated in the member model for buildings with slab stiffness, which requires an overlap of the upper and lower support axes of the elements. If the resulting segments are just inside the tolerance range, the FE mesh cannot be generated and an error message appears with the problem area circled. The following image shows a corresponding error message:

In this case, proceed as follows:

1- Open the slab level “L2”.
2- Visualize the elements of the lower (“L1”) and upper (“L3”) slabs.
3- Analyze the selected area. As there are no elements of slab “L1” in the marked area, the error can only be found in slabs “L2” or “L3”. In the present example all geometry is correct in “L2”. Therefore, the cause in the marked zone can only be found in “L3”. Due to the intersection of the support axes of walls “W20” and “W37”, a small wall section whose length is just within the tolerance range is created when generating the member model.

At slab “L3”, wall “W20” is divided by wall “W37” at an element that is just within the tolerance range.
Mark wall “W20” on the panel of level “L3” and then the point of the wall.

Now move this point in the Y direction to the wall axis “W37” as shown below. In general, the wall axes should always be modeled so that they meet and do not intersect.

Note: If, in addition to the case described above, adjustments are made to the support axes, note their different treatment in the overlapping slab model and in the member model. In the beam model, the central axes are used as support axes and not the support axes of the overlapping slab model.
