gearman New Member Williams Join Date: Sep 2015 Posts: 17 Rep Power: 11	Dear friends! I have a region of high pressure loss in my piping system.I want to insert a region similar to porous media in the piping system grid.The pressure loss in this region is equal to the square of the mass flow rate.How do I write UDF in this region.The inlet of the piping is the mass flow inlet and the outlet is the pressure outlet.Thank you in advance! udf.jpg
