Hello World.
All I wanted to do is as particle surface injection with specified Diameter and Density via UDF: Code:
#include "udf.h" #include "dpm.h" DEFINE_DPM_INJECTION_INIT(testInjection,I) { Particle *p; cell_t cell; Thread *cthread; loop(p,I->p) { cell = P_CELL(p); cthread = P_CELL_THREAD(p); P_DIAM(p) = 1e-3; P_RHO(p) = 1.0; } } One with the properties defined in the UDF and one with the properties defined unter Define / Materials. Why is that so? Does the UDF not overwrite the entry in the GUI?

I simply don't touch the input from the GUI via the UDF (so far). But I suppose your question is a little more general. For surface injection there is nothing to share. All informations are in the User Guide ...

Hi Sega,
I want to simulate a complicated surface smell. From this surface particles should to come out. I want to examine whether my air conditioning system functions. The particles should be only passive scalars. Oh, I just see this is a wrong forum, sorry, should be in OpenFOAM question Sometime I hate the search function on this website... my fault Bye Tian |

hi i want to do the same but i want to make particle generator in another program and make a file from it, and then i plug that file to dpm_inject udf to hook it up to the fluent. DO you solve it?
