Hi,
when I try to run distillation column calculation.There was a error saying " PR fugacity calculation error:unable to find z for liquid phase at NaNK and 101325pa.Index was outside the bounds of array."
Could you please help me to clarify this error.
Thank you.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Try switching the solving method from Inside-Out to Bubble Point. It will solve in a second. The IO method is currently broken, but a fix is on the way for DWSIM 3.
Regards,
Daniel

You can insert code breaks in the procedures inside the 'RigorousColumnSolver.vb' file, they're all there.
About the reactive distillation support, I still haven't read about the subject but it should not be that difficult since DWSIM already has a good reaction framework implemented...

Hi,
Can you attach your simulation file here?

Hi,
Thank you for your reply.
I have attached the distillation simulation.
Thank you.

Hi Wathsala,

Hi,
Thank you for reply.
Could you tell me how to see calculations being done inspecting the code during execution.
Do you have idea to add reactive distillation for unit operations in the DWSIM.
Thank you,

Hi,
Thank you for your reply.can you tell me where is the 'Rigorous column solver.vb' file.
I can't find it.

It can be found inside the "Solvers" folder:
