Hi! I am working with solids, and I have found the problem that there is no way to access the variables for Particle Size Distribution of a stream, neither in Hysys 3.2, nor through COM. Does anybody have any suggestions? Thanks!

Hi there! I have to create a Flowsheet tool for an engineering package. On the right part I would have a list of icons. Then, I should be able to drag them to the main flowsheet window. Then, I would be able to connect them with streams. Finally, I should be able to click on any stream or unit...

Hi! I have a solution that contains sulfate that is used to catch Cl- from a waste gas current. The problem is that I have to analyze it with liquid-liquid chromatography, and the conductivity of the solution is too high to inject it. The question is... how could I eliminate the sulfates, but...

Ok, I've found the problem. It is a documented error in Matlab r13's COM system; two Matlab files were substituted, and it has started working again!

I have been succesfully using Olaf Trygve's Toolbox for Hysys with Hysys 2.4.1. But now, with Hysys 3.1, it's not fully working. Matlab 6.5 says "Unsupported Variant Type" when using hyconnect. Does anybody know what's happening? How can I now communicate Hysys and matlab? Thank you!

Hi! I'm trying to send the composition for a material stream from Matlab through activex. I can send temperature and pressure, but it doesn't seem to accept vectors. I have also tried to send it as a cell, but no way. Any suggestions? Thank you in advance!!

As we all know, there are may powerful scientific programs written in FORTRAN. I want to reuse some of them in order not to write them again. I'm currently using Matlab 6.1. I tried to use "mex", but I discovered that matlab has no fortran compiler, and you have to install one. I...

Thank you very much! Your help has been really useful! Regards from Spain.

I'm developing a program in matlab that uses some windows, but I'm not using GUIDE. I've already finished the program, but I still have a silly problem... How can I tell Matlab to start the window maximized? Must be a silly thing, but I can not find the property. Can anybody help? Thank you in...

Thank you very much for your answer. I´m interested in the book you speak about, but I have a problem: Does it include internal geometry parameters for design? Or just provides pressure-flow relations? Thank you again.

Has anybody information on vacuum jet-ejectors design, operating conditions? Thanks a lot!

Has somebody worked around with the new EO features? Have many problems: - How can I make a connection in EO, to copy complete a stream into another one? - How do EO ports exactly work? Thanks for your attention.
