I have been trying to calculate Tg (glass transition temperature) for a standard cross linked polymer system formed between DGEBA and 44DDS. What I am afraid is that after normal termination of the job it produces a PDF file called "analysis.pdf" that shows some plots between various properties. The standard deviation for any plot is found to be too large for all of my attempts, regardless of the system size used (viz. 100/60 units of DGEBA and 60/40 units of 44DDS in the cross-linked polymer, for example). Please note that I am using all default setting for my calculations of Tg. Should there any specific parameter (rather than default setting in pipeline pilot) that needs some care to remove this kind of abnormal standard deviation? I have attached with this message a snap of the strange error I just mentioned above. Any suggestion on how to improve this would certainly be appreciated.
