Scott Sibole says: "I believe these are all the files you need to run the tg script. Hopefully, your path for tg is C:\Truegrid in which case all you need to do is create a folder called iges in that directory and place all the iges files in there. Otherwise all iges commands issued in the script have to be changed to be concurrent with your path. Also there is a binary file of the surfaces which needs to go in C:\Truegrid\Examples along with the .tg file itself. I also included the input file, since I fixed some negative elements in ABAQUS. You may want to just use the nodal definitions from that file since they are all positive. Let me know if something doesn’t work. Different versions of TG seems to cause problems sometimes."
