G'day Everybody,
Currently modelling a gas line that starts from a wellhead with the following known displacements: At initial start up the wellhead rises by 5inch due to thermal growth and during operation it moves laterally by 3inch on either direction. Just a bit confused in chapter 3-3 of the application guide where it says that "Once a degree of freedom has been fixed in one displacement vector, it cannot be free in another displacement vector at the
same node (leaving a displacement field blank will default to zero in this case)." How I modelled this is I placed a 5" displacement on all of the vectors (ie Vector 1, vector 2....) as the 5" displacement will be true for all ope case. I then placed a 3" displacement on the Z direction for vector 1 then a -3" displacment for Z of Vector 2 while making all the other values 0. Is this correct? Thanking you all in advance.
