Hello everybody,
I programmed a 3D modell in Ansys APDL where a current flows through a copper tube. There is water going through the tube for cooling. Now, I simulated the energy (W/m³) in the tube generated by the current. So, I would like to couple the results with fluent, so I exported the geometry into fluent. To get to know UDF better, I wrote a simple (but working UDF) which gives a constant W/m^3: #include "udf.h" DEFINE_SOURCE(energy_source,cell,thread,dS,eqn) { real source; source = dS[eqn] = 10000000; return source; } I imported this file in Fluent by adding sources and chosing the c.file. So right now, the copper tube in fluent is provided with a constant energy of 10e7 W/m^3. But as I said, I would like to adapt the W/m^3 results I had from Ansys APDL into Fluent (each element shall have the W/m^3 that is created by APDL). I don't really know how to do this since I have just a bit experience with UDF. I have looked through the manual but I could not receive the necessary information input to solve this issue. Can somebody explain me how to realize that? Best regards h0rst |

Does nobody have an idea?
I wrote the APDL results into an array and text file gives me in the 1 column: jouleheat 2 column: cent x coordinates 3 column: cent y coordinates 4 column: cent z coordinates But how can I read this array into my fluent udf? h0rst |
