I like that my models are easy for me understand which makes it easier when explaining them in meetings with stakeholders or other people who have not used power plant modeling systems before! It's very useful if you're new at this field, but also has lots of functionality so you can use what suits your needs best. There is nothing really bad about using uplanace as they support all major operating system (Mac & Windows). The only thing i don't particularly enjoy doing while working with uplan ace is having less control over how long calculations take compared to others software out there such as EPF7/EPIsoft Powerplant Designer Pro etc.. This could be because its more advanced than some competitors products and therefore takes longer time? But overall everything else works well enough without any problems found. We mainly work within our own organization making simple optimization plans where we try different scenarios until.
