Sandilya Guest Posts: n/a	Hi I am writing a UDF to intialize the particle velocity of particle injection in my DPM model. I have looked up macros but not able to get the right UDF. When I interpret the UDF into the prgrm the compiler says : Error: C:\---\prtcl_init_condn.c: line 14: structure reference not implemented Can anyone tell me what this means!!! Also what is the basic structure of UDF to define its velocity? I have seen an example in manual but the example is of "surface reaction" and I could not understand it to apply to my cxase. Thank you Sandilya Garimella
