 May 22, 2012, 18:56 Solar Flux field function #1 Member   David L Join Date: May 2012 Posts: 43 Rep Power: 5 Solar Flux Star CCM+ Hi guys, I have data for direct Solar Flux for a cylinder from with insolation, and im trying to simulate the "changing of solar flux as a function of position" Instead of constant solar flux of 1000w/m2... Hope you can help me our? an example of a function could be: Solar= cos(teta) 1000 * C * Z Where C and a are constant, Z and teta position in the cylinder. Or maybe sett up a table? Many thanks

I meant my flow is dependent only the theta and same in z. I want to do my first field function with star ccm+ and I need something that the star ccm+ help ### Referencing Local Coordinate Systems \$\$Centroid(@CoordinateSystem("Laboratory.Local Coordenate System.cylinder"))[0] #### Interpolating Scalar or Vector Data as a Function of Another Table Column interpolateTable(@Table("data"), "funtion", LINEAR, "thete", LINEAR) ### function could you help me? Many thanks
