CheFEM 3 Software
CheFEM 3 is a 'Chemical-FEM' simulation tool designed for polymer and composite based applications, providing significant advantages. It minimizes exposure experiments, thereby saving costs and reducing environmental impact. Utilizing advanced computing power, it analyzes chemical exposure scenarios and predicts service life, effectively managing equipment operational expenditures (opex)[1] [2].
Principles
Utilizing calibrated Sanchez-Lacombe Equation of State and, when necessary, other Equations of States (EOSs), CheFEM 3 accurately predicts crucial material properties such as permeability, chemical resistance, and mechanical response[3][4][5][6] . CheFEM 3 operates as a standalone application or integrates seamlessly with other FEM packages like Abaqus, Ansys, and SolidWorks, enhancing workflow flexibility.Development of the software was initiated by the Polymer Science group of the University of Groningen, The Netherlands
