OpenProcessSim Release 0, is based on a computer aided design project I did many years ago at university. The project was part of a short introduction to FORTRAN and was to model in FORTRAN a fixed flow network, and write a mixing routine as a Subroutine and allow the user to be able to specify the flow rates of the five inlet streams. I built this first release of OpenProcessSim based on the FORTRAN model I wrote, as a hommage as although I never considered the possibility at the time my engineering career as been in process simulation.
The process flow network modelled in OpenProcessSim Release 0 is shown below.
In OpenProcessSim Release 0, the only equipment modelled is a process mixing point, inline with the requirement of the original project.
In OpenProcessSim Release 0, the scope of the simulation is fixed, as shown in the Process Flow Drawing above.
The flow rates at model inlet boundaries A, B, C, D, E are specified in the file ./model/data.txt (The flow rate for these streams is assigned based on the order of the file. The boundary names in the file are "for show" and are not used to specify the stream. (Changing the order in the file will not give the expected results.))
The value of model outlet boundary X is fixed in the model as 10.0
When the model is executed, the file ./model/data.txt is read and the results of the simulation (the flow rates of all the streams in the modelled process network) are written to the file ./model/output.txt
