The International Journal of Multiphysics is an open-access scholarly journal dedicated to research that brings together multiple scientific and engineering disciplines. It publishes peer-reviewed original research articles, review papers and communications, with a focus on theoretical developments, numerical modelling and experimental investigations. Its coverage includes both fundamental research and industrial applications, supporting work that uses simultaneous modelling to understand complex physical processes and contribute to safer, more efficient and environmentally friendly products.

The journal explores combinations of fields such as acoustics, electrical and magnetic systems, fluids, fire, explosives, soil, structures and thermodynamics. Its aim is to provide a focused publication venue for multidisciplinary findings that might otherwise appear across separate disciplinary journals or conference proceedings. Published quarterly, the journal welcomes research relevant to academia and industry, and its editorial board includes internationally recognised specialists from both sectors. The journal is listed as open access, charges no submission fee and publishes articles under the Creative Commons Attribution 4.0 licence, with authors retaining copyright. Its ISSN is 1750-9548.
