Molecular-, fluid- and field-dynamics simulation are becoming more mainstream tools for practicing process engineers; here, the academic community needs to pay close attention to "upskilling" demands from industry, where remote working/training emphasizes the need for sophisticated computational-engineering design tools with molecular focus. In this integrated-simulation 'vision', spanning the molecular- to plant-design scale, it is argued herewith that academic-industry cooperation is essential to achieve progress in professional multiscale computational-engineering training, from undergraduates to practicing engineering professionals.
