Hello!!
I am solving 3D solidification problem. In my geometry, there is mold which is open to the atmosphere in which liquid is solidifying and in center of the mold there is a solid copper rod. There is heat transfer radially outwards and heat transfer takes from all mold surfaces. In this problem, I am attaching udf with define execute at end macros which is shown below : In boundary conditions: interior fluid zone id is 2 DEFINE_EXECUTE_AT_END(time) { cell_t c; Thread *t; Thread **pt; Domain *dd; dd=Get_Domain(1); t=Lookup_Thread(dd,2); // pt=THREAD_SUB_THREADS(t); thread_loop_c (t,dd) { /* loop over all cells */ begin_c_loop_all(c,t) { // if(C_LIQF(c,t)<1) // { // C_UDMI(c,t,0)=C_UDMI(c,t,0)+RP_Get_Real("physical-time-step"); // if(C_LIQF(c,t)==0) // { // flag++; // if(flag==1) // C_UDMI(c,t,1)=C_UDMI(c,t,0); // else // // } // else // C_UDMI(c,t,0)=0; if((0<C_LIQF(c,t))&&(C_LIQF(c,t)<1)) { C_UDMI(c,t,0)=C_UDMI(c,t,0)+RP_Get_Real("physical-time-step"); } } end_c_loop_all(c,t) } } I am getting a segmentation fault in if condition line. Please help me with this. Regards |
