Aspen, please input fluosilicic acid; seeking help
Thread Content
I would like to ask everyone: how do I enter fluorsilicic acid in Aspen? The built-in structural formula shows an error
Enter CAS: 16961-83-4
I can add this in, but the displayed molecular structure is incorrect; subsequent attempts to calculate the binary parameters do not converge, and I’m not sure how to enter the correct molecular structure.

The binary parameters can either be found in databases, determined through regression of experimental data, or estimated using group contributions – they cannot be calculated directly.
