Hysys Matlab interface to set the mass flow rate in hysys composition tab from Matlab.

Dear all,

I am trying to optimize a LNG plant by using Matlab, and the design variable includes LNG mass flow rate / mass fraction. At each iteration of matlab the LNG mass flow rate of refrigerant component gets changed and a pop up botton shows up to accept the new composition of mass flow rate. Then i need to accept the new composition manually by clicking ok. How could i directly do it from Matlab by using some codes.

Dear sir, have you solved this issue? thx.

Dear Wang, still now i didn't get any solution. I am also facing another problem that the mass fractions of most of the components are not changing. Hysys is not accepting new mass fractions / mass flows. I tried the hysys case study to see how could i change them. But, in the case study the mass fractions are not changing also. Do you have any solution ?
