Gapuni nodes collection

HI,

When measuring reaction on areas where there are external forces, the reaction result is not accurate as it subtracts the external force.
One solution is to consider Only compression and extract the reaction at the gapuni nodes not the model itself.
¿Could the gapuni nodes collection that are later fixed be selectable so one can request their RF history output ?

NOTE: I can do it with custom cards , it’s just a matter of make it easier.

Regards

To prevent the averaging of the stress from GAPUNI elements used for the compression-only constraint, PrePoMax creates two sets of nodes. One set is connected to the mesh using the *Equation card, and the other is fixed to the ground. Are you interested in the second group?

And do you need to see this group in the History output creation window only?

Hi Matej and thanks,

The interesting set is the one that delivers RF and it is clean without distributed loads like gravity or Hydrostatic pressure. I guess it is the one where you apply the Boundary condition and fix it to the ground.

If it doesn’t overload the results it would be nice if one could also check individual node values if you mean that.

I would not like to expose the internal node set to the tree, but I can show it in the list of node sets when the region method is changed to Node set names.

That should work too. Thanks.
