Capricorn New Member Join Date: Dec 2015 Posts: 8 Rep Power: 11	I am simulating gas solid flow in a periodic domain of 0.640.64 m with 512512 grid points. I am using eulerian model in ansys fluent and two fluid model equations. I want to simulate it for 20 seconds with the time step size of 0.0002... Problem to write a udf to calculate solid volume of fraction in each cell....is it even possible???anyone can provide any similar udf like this???
