Hello guys, I have a custom fermentation block that I want to plot the solution array of the ODE on the Spreadsheet. However I'm finding it difficult to send the data. Here is the piece of code I tried after reading countless posts and tutorials of Python Scripting in DWSIM. Spreadsheet = Flowsheet.FormSpreadsheet for i in range(0,n-1): Spreadsheet.Worksheets[0].Cells[38+i,0].Data=sol[i,0] Spreadsheet.Worksheets[0].Cells[38+i,1].Data=sol[i,1] Spreadsheet.Worksheets[0].Cells[38+i,2].Data=sol[i,2]...

Good afternoon. Thank you Daniel and all the involved on making this incredible software of which I am a big fan. I am kind of a "Jehovah Witness" of DWSIM. Is Reaktoro PP supposed to work on DWSIM 6.7.0? I create a new simulation with sodium, hydron, hydroxide, sodium hydroxide and water, and when I try to add a new material stream, the software crashes. Already tried reinstalling and there's no use. Any tips?

Doing more research, I have an insight of what maybe wrong with the calculations. I observed that the "Concentration Profile" is ending not on L, the expected reactor length, but on 10L, ten times the expected value. Maybe this is tampering with the conversion results?

Hello everyone. I am trying to simulate the PBR reaction that is avaiable on Example 4-6 of "Elements of Chemical Reaction Engineering" by Scott Fogler. The reaction is C2H4 +0,5 O2 -> C2H4O, isotermical operation, 260 °C, Pfeed = 10 atm. In the feed: Molar flow of C2H4 is 1,08 lbmol/h, molar flow of Oxygen is 0,54 lbmol/h and Nitrogen (inert) is 2,03 lbmol/h. Fraction of emptiness is 0,45. Catalyst density is 120 lb/ft³. Catalyst diameter is 0,25 in. PBR diameter is 1,61 in. Law of reaction rate...

Good afternoon, everyone. I have a simultaneous adjust problem. I have two adjusts on a CSTR: One controlling the Residence Time of the Liquid of the CSTR, by manipulating the liquid Volume, and one controlling the residence time of the vapor of the cstr, by manipulating the Headspace. Thing is: changing the liquid volume also affects the residence time of the vapour and changing the headspace also affects the residence time of the liquid. What happens in the flowsheet is that first the liquid residence...

Changing the flash algorithm to VLE solved my problem. For this simulation, that has lots of user-created compounds, I'll stick to the VLE Flash forever so I avoid future problems. Thanks. King Regards,

Greetings, DWSIM fans! After the new update, the outlet stream of the conversion reactor are simply not calculating the thermodynamic properties, and are showing zero value. Any clue? Take a look at the file attached.
