Answer:
One reason for the error message may be that the surfaces were generated from members with foundations. These members are then converted to null members. However, the member foundation is preserved and still assigned to the null members (see Image 02). It is often not possible to carry out the adaptive mesh refinement. Therefore, we recommend removing member elastic foundations on the affected members first.
Question
After generating surfaces from a few members, I can no longer mesh the model adaptively.
