Solving methods of wind quantity in complex ventilation meshes which includ wind pressure source are researched. A general matrix model of ventilation meshes and new iterative formulas are proposed. Two computing examples are given and the results shows that each branch' s wind quantity can converge the stable value by several times of iteration for any iterative initial value. The proposed model is suitable for wind quantity computation with complex ventilation structure of electric machines.
