UDF problem- time dependent temperature at inletHello everyone,
I am relatively new to UDF and I am facing a problem in interpreting an UDF defined by me. The UDF is a time dependent temperature profile for the inlet of 3D model. While interpreting the UDF, I received a problem stating that there is an error in line 11: subscripted expression is not an array or pointer: int. the UDF is as follows, #include "udf.h" DEFINE_PROFILE(temp_inlet, thread, position) { face_t f; real X[ND_ND]; real t = CURRENT_TIME; begin_f_loop(f, thread) { F_CENTROID(f,thread,position) = (3.0e-10*t*t*t*t*t) - (3.0e-07*t*t*t*t) + (0.0001*t*t*t) - (0.0217*t*t) + (1.8728*t) + 70.839 } end_f_loop(f, thread) } I would like to know if this UDF is correct and also will it work on HP cluster (parallel nodes)??:confused: If this UDF is wrong please give me suggestions to improve it. Thank you in advance |

Please use the Power sign. 10*t*t*t**t*t is different than t^5 or 10^5 F_CENTROID(f,thread,position) = (3.0e-(pow(t,5) - (3.0e-07*pow(t,4) + (0.0001*pow(t,3) - (0.0217*pow(t,2)) + (1.8728*t) + 70.839 Shane |
