Optistruct - No Separation contact simulation

Dear all,

 

I'd like to ask you for help regarding specific contact simulation.
Please have a look at the sketch below (I know that this particular case can be easily calculated analytically /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' /> ).

 

There is a L-shape profile (on the right) which is screwed in to a flange on the left.
There are two types of connection:

• Pin connection - pins transmit shearing load (red)
• Bolted joints which ensure flanges integrity (blue)

 

There is also a contact plane marked in yellow.

 

 

I have modeled pins explicitly with merged nodes between flanges as shown on the figure below.

 

My question is how to model the contact between blue and dark yellow elements?
Ideally it would be kind of no separation contact so both surfaces remain fixed but no shear load is transmitted.
I want the pins to carry all shear load and I'm not interested in the bolts assessment.

 

There is a nice presentation about optistruct contact settings - 

And even contact type 'NOSEP' is described but I can't find it in my v13.

 

Could you please give me any advice?

Thank you in advance.
