Computational Fluid Dynamics and Finite Element Analysis are computational modeling techniques used to simulate the effects of many physical phenomena and predict the results. Many physical phenomena can be solved with these modeling techniques, from mechanical analysis to heat and mass transfer, electromagnetic analysis to explosion analysis. When a physical event is modeled correctly, and the software settings are made perfectly, valuable information and values can be obtained without performing experiments on this physical event, and risk analysis and designs can be made according to these data. When the computational modeling technique is used to model explosions, precious information about physical quantities such as shock wave propagation, pressure and temperature distributions, and flow rates after the explosion event is obtained. With this information obtained, precautions that can be taken to reduce the effects of explosion risks can be determined, and safer buildings and infrastructures can be designed. Due to explosions that occur almost everywhere in the world because of war or terrorist attacks, many buildings and infrastructures are damaged, and living beings are injured or die. In this study, information is given about some of the computer software and their features used to predict the reactions of buildings against explosion risk and to make them safer.
