Simulation, fail to mesh one weld on a shet metal part having two welded corners.

Have a problem with a sheet metal part which have two welded corners... when generating the mesh for the part, only the second weld is recongnized by the software which only mesh that weld leaving the other "open", therefore the analysis of the part do not produce a valid result.  Any one have this problem before and know how to resolve it?  apparently are some bugs on the sheet metal corner welds..., how I can simulate them in the anlaysis (if the corner welds are not reconized by the mesh),  a bonded contact is not an option since there is a gap betwen the flanges and both are on the same part.

 

I can model the part as a solid (no sheet metal) but them the software takes for ever to generate the mesh and run the analysis (it is a very large part of 0.1046" thickness with over 3500 in2 of area), and the assembly have 16 of those parts.

 

We are using SW 2009 sp 5.0 with Simulation Professional.
