Simple shell element FEA

Hi everyone! First time posting here.

I've got a simple problem - I've made a 2D block made of shell elements that is fixed along the bottom. Point loads on nodes of the shell elements push downwards (negative y-direction).

For some reason I'm getting 0 reaction force in the y-direction all along the bottom of the block when I use the 'Reaction Forces' component from results. What am I doing wrong?

Thanks for your help.

Best,
Umar

Dear Umar,

could you please internalize the boundary curves or add the 3dm-file?

Best,

Clemens

Dear Umar,

the output of the reaction forces correspond to the local coordinate system provided when creating the supports. This is not made clear in the help-text of the 'Reaction Forces'-component. Thank you for your hint!

If one removes the 'plane'-input at the 'support'-component the reaction forces come out in the global coordinate system (see attached definition).

Best,

Clemens
