I am working of liquid fluidized beds. I am tryng to simulate two dimensional fluid-solid flow. I want fluent to calculate the superficial fluid velocity at the end. How do I get that? Can I get them from surface/volume integrals? Thanx. BZ.

 October 24, 2010, 19:33 Thanks. #3 New Member   Join Date: Aug 2010 Posts: 6 Rep Power: 9 Hi. I have already posted the following lines in my earlier post. Can u plz have alook at my situation and advise me accordingly. I have a 2D (x,y) domain of size (0,0)(xmax,ymax) divided into a 50x50 grid. I want to find properties (e.g. y-velocity) of all points at any given instant in the following manner. for (y=0,y=ymax,y++) { for(x=0,x=xmax,x++) { location[x][y]= ........ ? y_velocity[x][y]=........ ? } } It means that I fix y, then loop over all available x-cells to store values. Then increase y and repeat the process for x-cells. I need to store the values in arrays for further analysis or written to files. How do I add it to my UDF ? Thanx.
