Hi there,
I'm trying to write a UDF for an periodic heat source. The UDF should look like a saw tooth thread design. I'm very new to UDF, but In my opinion the errors are in the first lines (in the "initialization") - It should be a transient funcion (heat source depends on time) - Heat is generated in an Interior (3D) Maybe someone of you see the mistake(s) in this UDF include "udf.h" Define_Source(heat_function, c, t, dS, eqn) { real t = CURRENT_TIME; { if (CURRENT_TIME > 151.76) heat_flux = 0.1; else if (CURRENT_TIME >= 2.24 && CURRENT_TIME <= 2.96) heat_flux = 200000; else if (CURRENT_TIME >= 27.04 && CURRENT_TIME <= 27.76) heat_flux = 200000; else if CURRENT_TIME >= 51.84 && CURRENT_TIME <= 52.56) heat_flux = 200000; else if (CURRENT_TIME >= 76.64 && CURRENT_TIME <= 77.36) heat_flux = 200000; else if (current_time >= 101.44 && CURRENT_TIME <= 102.16) heat_flux = 200000; else if (CURRENT_TIME >= 126.24 && CURRENT_TIME <= 126.96) heat_flux = 200000; else if (CURRENT_TIME >= 151.04 && CURRENT_TIME <= 151.76) heat_flux = 200000; else heat_flux = 0.0; } } return heat_flux; |
