You use individual PIPESIM modules for a wide range of analyses, including well modeling, nodal analysis, field planning, artificial lift optimization, pipeline design, and equipment sizing.
Differently from Olga Unisim (unfortunately) does not use text input or output files, the only way to communicate with the software is via a COM interface using pywin32. In this course, you explore PIPESIM production system analysis software that provides steady-state, multiphase flow simulation for oil and gas production systems.
UnisimDesign is mainly a process simulator but can be used also to simulate pipelines or networks in particular providing some external components. The simulator has text input and output files with pyfas you can expose Olga results to python (both trends and profiles) or dump all the results to excel/csv for your post-precessing. Olga is the standard de facto for the dynamic simulations of multiphase systems (single pipelines or complex network) in the oil and gas indistry.
