in abaqus profile i have 2 coupkins connected with B31 in middle which are seperated initially, (PFA)when i given nodal equivalence , it shows like equivalenced but still i can see a free node over ends of B31may i know i to solve this issue
I am not able to see the free node from the image.
You can verify if it is free by using this tool
can you check here
in the image as you can see 4 nodes are selected, it is suppose to be 2 nodes if it is connected.i have created rigids in current modal and imported B31's from other model B31 is placed in perfect position but equivalence is not working.even i check free 1D nodes from the above panel you mentioned. it is displayed as 2 nodes are free
