BCHANGE in SOL103?

Benny Hill
Sometimes it might be useful to have more control about glued areas between two bcbodies in SOL103. In SOL101 and SOL400 I can use BCHANGE to achieve this but this option is not available in SOL103. My current workaround for SOL103 is to define additional bcbodies only containing the elements which should be glued. This is a lot of work and often leads to the following warnings in the f06 file because two bodies share the same nodes:
 
"warning: node    11764 belongs to bodies  28  33. for the contact algorithm it will belong to body   33 only."
 
Will the BCHANGE option or something similar become available for SOL103 in future releases of Nastran? Is there a smarter way to gain more control about glued regions in SOL103? Thanks for any suggestion!

    SOL 103 is linear and Glue contact is only option supported for contact bodies. Touching contact in SOL103 is not a option or more pointedly not meaningful. So generally use of BCHANGE in sol 103 in not necessarily warranted and there is no real performance benefits to be had with BCHANGE it, as time needed for contact boundary calculation will be much less then time required for eigen solver. In light of this it is unlikely that it will be considered for future impelmentation and especially it makes more sense in the nonlinear context.
