Erik, I see what your original point was now that I opened the ds.dat input file and found an element type 201 for the follower element and the keyop,3,1,1 to keep the direction from changing!

In this model, the type ID for the FOLLW201 element is 3 so the Keyops are as shown below.

Thank you for the help Erik!
