T-Junction Connectivity

Dear Forum,

 

I am trying to simulate a 3 point bending test of a composite beam.

This beam has inner ribs to create more stiffness.

 

But when the analysis runs, there is no stress/strain on these inner ribs. See picture
What can I do to correct this.

I first draw CAD geometry, using surfaces.
I split the surfaces on the contact edge, to assure a proper t-junction edge. (Yellow edges in the picture)
Then I import Geom; mesh ect (the rest is history).

 

Thanks in advance

Arne

PS any other pointer are also welcome

    I found the mistake

    I had to re-mesh after controlling the edge connectivity
