A numerical method based on a general multiblock structured g,id system is presented for the simulation of wind flows around complex buildings. The basic equations are transformed into a generalized coordinate system and discretized with a finite volume method. To achieve continuous distribution of the physical variables at grid singularities, we introduced the correction process for right-hand side terms of the governing equations among the connected blocks. The method of artificial compressibility is applied to avoid the decoupling of the pressure variable from the velocity field. The computations of the laminar flow over a circular cylinder and the turbulent flow around a dome structure are presented for a validation of the solution algorithm. To demonstrate the capability of the developed method, a flow simulation over a complicated marine structure is also included.
