hello,
I am solving solidification problem. I want to track a particular liquid fraction contour i.e. 0.7(C_iiqf=0.7). The final aim is to single out cells where liquid fraction is 0.7 and calculate temperature gradient value at that cell. to track cells with liquid fraction 0.7. I followed following algorithm. 1. check whether the value of liquid fraction in particular cell is 0.7 2. if yes, A user defined memory(which I defined before) will have a value of 1. 3. if no, the user defined memory value will be 0. 4. loop over all cells and threads. here is my UDF #include "udf.h" DEFINE_EXECUTE_AT_END(temp_gradient) { Domain *d; Thread *t; cell_t c; d = Get_Domain(1); thread_loop_c(t,d) { begin_c_loop(c,t) { if ( C_LIQF(c,t)==0.7) { C_UDMI(c,t,1)=0; } else { C_UDMI(c,t,1)=1; } end_c_loop(c,t) } } } I am expecting cells where liquid fraction is 0.7 have udm value 1 and rest cells have udm value 0. but at the end of the calculation I am getting all cells with udm value 1. when I displayed contours of liquid fraction in solidification/melting I am getting region with liquid fraction 0.7. |
