We have troubles with the LINK command in Feap 8.3
In previous versions of FEAP that I used, a sequence like
would link for instance the x and y DOFs of nodes 11 and 12.
However, the same sequence used in Feap8.3 leads to an error message even though the 8.3 manual seems to indicate that the format for the LINK input is still the same:
node-m1 node-m2 inc-m1 inc-m2 id1 id2 ... id-ndf
node-n1 node-n2 inc-n1 inc-n2 id1 id2 ... id-ndf
... ! repeat for additional node ranges
! blank termination record
The error message we get is
"No file named link0000 exists"
IS there anything that changed and I missed to account for in this input?
Thank you for your help,
