I'd like to know how to display the reaction force vectors in a 2D planar unsteady fluid flow

analysis like the example below:




I enclosed an example where the Reaction Forces button doesn't work.

I did not have the time to look at your model, but chances are you need to activate the option to calculae the reaction forces before you run the analysis. If I remember correctly, it is located under "Setup > Model Setup > Parameters > Output (tab)" and you will see where the reaction force option is set to "do not calculate" by default.


Hope this is the solution.
