I worked out that the problem may have been that I was using the built-in compiler when compiling the UDF which was giving me a warning about not finding visual studio compiler. I am now not using the built-in compiler however now I get this error message 'fatal error C1128: number of sections exceeded object file format limit: compile with /bigobj'. This is because I need to include a large number of arrays with all the coordinates at each time step in the UDF. 

I found a solution for this here - however when I try to include /bigobj in the makefile_nt.udf file I cannot save it as it gives me an error message about permissions. 

This thread summarises quite thoroughly what I'm aiming to do with prescribing the node position at each time step,
