The aircraft was on a passenger flight from Tehran (Iran) to Khorramabad (Iran). The TU-154 crashed into mountainous terrain in poor weather conditions while on approach to Khorramabad. All the 118 passengers and crew members onboard were killed. This was the beginning of this project. The Hydraulics Laboratory of Civil Engineering Department of University of Tehran was assigned to model Air Flow near this airport.

The ansys model was a compilicated model. The elements of model were Hexagonal prisms. So the cacluations were very dificult. My duty was, designing a software that can analysis the outputs of ANSYS software and calculate the required data in any point of the space.
