Air flow is one of the most important components of outdoor comfort, which is affected by many factors. The current research has investigated the effective factors in creating comfort against wind behavior in the space between the blocks in a residential complex. The studied example is a residential complex consisting of 12 mid-rise blocks in Omid town of Tehran. In this regard, the general area of Omid residential complex and the geometric form of the blocks were modeled and different points of the site were coded. Then the effect of wind speed in different points of the open space between the complexes was eva‎luated with the help of Ansys Fluent software and Butter Fly plugin. This research was conducted in the form of a mixed method. For this purpose, in the beginning and in the framework of qualitative studies, the qualitative components affecting the comfort against wind flow in the landscape design of the spaces between the building blocks were identified from a descriptive method with the help of library study tools, and then with a quantitative look and using Wind flow modeling, inter-block spaces were analyzed. CFD modeling and numerical analysis were done first with Butter Fly software and then with Ansys Fluent software to increase accuracy in data analysis. Based on the results of wind flow modeling, the points where the comfort of pedestrians in the inter-block spaces of Omid residential complex were endangered were identified. Next, based on the findings of wind analysis and superimposition of the coded areas, a comfort level zoning map was prepared based on the intensity of wind currents. Finally, the design of these areas was done according to the need of each to provide a level of comfort against the inter-block winds.
