Why does the RFEM issue Error No. 2306 "Solids No. []. The solid's boundary surfaces are not closed on the lines []. Please check Table 1.5 or the corresponding table." when starting the mesh generation procedure? 


This message is related to an incompletely defined solid.

Presumably, the solid definition has been destroyed while entering other elements. In this case, open the solid text definition and check the input of the boundary surfaces for completeness. It has to be ensured that the set boundary surfaces result in a "watertight" solid.

If the error occurs despite defining all surfaces, check the model for double lines. The following FAQ helps here.
