New entries into Thermodynamic database

Hi,

I am looking for a piece of advise on how to put a new entry for a new type of “Glass” into the database attached to ToughReact v3.3.

Looking at the file I have, there are already 3 lines of entries for 3 types of “Glass” (ThoughReact v3 attached database). Looking into the user guide of ToughReact, for the 8 items of temperature range, one may expect the first line to be the molar volumes of the spices, the second to be the heat capacity and the third one, heat conductivities. But the values from 2nd and 3d lines are both irregularly negative and positive for different temperature. Could you please comment on what is the correct understanding of these entries.

Is it the right way to do it by making a copy of the database and put additional 3 lines for the new “Glass” and use it for the next run?

Appreciate your response
