COFE is an intuitive graphical user interface to chemical flowsheeting. COFE has sequential solution algorithm using automatic tear streams. COFE displays properties of streams, deals with unit-conversion and provides plotting facilities.
COFE flowsheets can be used as CAPE-OPEN unit operations; so you can use COFE Flowsheets as unit operation inside COFE (flowsheets in flowsheets) or inside other simulators.
COFE 3.3 was released on November 11, 2018.
COFE 3.2 was released on September 28, 2016.
