can any one tell me what is meant by mesh orientation in north and east in solar radiation model

The solpos code from NREL determines the sun's location. But the cfd model needs to be oriented relative to it. It cannot assume that the x-axis is pointing east and the y-axis is pointing north because the model may not have been created with the geographic orientation in mind. By giving a vector (in the model space) that points North and East, the solar load model can rotate the sun location appropriately..
