Twenty papers were presented on the use of EcosimPro for simulation in a number of fields, including aerospace, fluids, power plants, processing plants, optimisation, chemical modelling. There was also a roundtable on future EcosimPro developments during which all users could voice their opinions on potential improvements to the tool. The papers can be downloaded from this website.
