Rigid Link (Blocked Directions)???

505 Views, 13 Replies

I am using rigid links on a structure to simulate lifting lugs on the perimeter of the structure.  When creating the rigid link there is an option to specify "Blocked Directions" there are checkboxes for UX, UY, UZ, RX, RY and RZ. Would somebody be able to explain to me what RSA means by these "Blocked Directions"?

 

Also, Which node do you select as the Master/ Slave when creating these rigid links? And is there a way to delete a rigid link if you no longer wish to use it?

 

Thank you,

 

Jared

Thank you.

I have another question about rigid links. When i verificate my model sometimes it gives me warnings about isolated nodes, and when i check to see which nodes are they, they always are the nodes that I use to place the rigid links between 2 bars. Is it normal?

Thanks again for your help.

It does not happen every time. In this moment it happens only at node 1540, it is what the verification says.

And when i run it, now i get inestability type 3 in node 1383. I really don not know why this happen. I made the calculations like 15min ago and did not get any inestability nor warning of isolated nodes. They seem to appear out of nowhere. I was to attach the file. But its size is a bit larger than it is accepted here in the forum, is there any other way i can send it to you?

Hope you can help me.

Thank you.
