Hello, I can answer your first question. You can activate the posdat.f from the Star Guide-> Analysis Controls-> Analysis Output: Acivate the user subroutine for printed data. Or you can use the following command: prfield, none, , ,user (try help prfi) I hope this help, Allan

The error you are getting means that you are using the user subroutine coteet (specific heat calculation) and the value of TUB you are returning is less than SMALL (SMALL is a code defined small number used to avoid division by zero).

Please check your user coding and/or contact support.

For more info on user coding and NT please see my thread in this in this forum.
