अन्तर्राष्ट्रीय सिमुलेशन प्रतिस्पर्धा or International Simulation Olympiad (ISimO) is an online global olympiad to promote and celebrate the excellent computational (simulation) engineering happening in academia around the world, using open-source software. ISimO, organized by Paanduv Applications, invites all students (bachelor level, master level, or PhDs) to register for the event on an individual basis or in teams. Applicants can be full-time registered students at any academic institute.

Because computational engineering is applicable to a wide range of industries, applicants can select one from a list of problem statements. Broadly, the problems will be categorized into three categories: Multiphase flows, Aerospace Engineering, and Thermal Engineering. Students from mechanical, aerospace, thermal sciences, civil, chemical, electrical, electronics, materials, applied mechanics, mathematics, physics, chemistry, ocean, material science, additive manufacturing, health sciences, mining, and other backgrounds are welcome to register. The difficulty level of each problem will be intermediate level, will involve the validation of experimental data using computational modeling, and will be evaluated based on many or all of the 8-point evaluation criteria described below. The panel of judges will include computational engineering experts.
