How to input substances that are not available in Aspen

2018-05-19View Original

Thread Content

When using Aspen for simulations, I encountered the dimer of methyl methacrylate (with hydroquinone as a polymerization inhibitor), but this substance is not available in Aspen. Could some experts please advise me on how to define it and input it into the system? (There are no parameters available for it at the moment.) Thank you!

One method I know: draw a molecular structure model and customize the components
