In jacket models, there are requirements of having a connecting member which takes compression/tension only during certain operations. In SACS, such a member can be modelled using GAP element.

Currently in MOSES, such a feature is not available. If we have a member (just like BEAM/TUBE) and can define this connecting member within a body or part, it would be an added feature.

Also, while converting a SACS model with GAP element to MOSES, they are not converted to MOSES. We may have to use GSPR elements in MOSES to replicate it. If MOSES can introduce a new connecting member, this issue also can be sorted out.
