Hello Guys,
I have a question regarding saving certain values into a text file or excel file. Can I save the values that I am asking my UDF to display? In my case DT_CG and Spring Force as shown in the UDF below? The reason is I want to plot a graph of DT_CG/Spring Force with respect to time. Any help would be appreciated. I am aware it is a DEFINE AT END Function but I just need help on how to set it up. Thank You #include"udf.h" #define spring_constant 300 /*N/m*/ #define original_valve_cg_y 0.029972 DEFINE_SDOF_PROPERTIES(spring_check_valve, prop, dt, time, dtime) { real valve_movement_y; prop[SDOF_MASS] = 0.00297817; prop[SDOF_IXY] = 3.33709e-12; prop[SDOF_IXX] = 2.27698e-06; prop[SDOF_IYY] = 2.53895e-07; prop[SDOF_IZZ] = 2.53088e-06; prop[SDOF_ZERO_TRANS_X] = TRUE; prop[SDOF_ZERO_TRANS_Z] = TRUE; prop[SDOF_ZERO_ROT_X] = TRUE; prop[SDOF_ZERO_ROT_Y] = TRUE; prop[SDOF_ZERO_ROT_Z] = TRUE; valve_movement_y = (DT_CG(dt)[1] - original_valve_cg_y); Message("DT_CG = %e, %e, %e\n",DT_CG(dt)[0], DT_CG(dt)[1], DT_CG(dt)[2]); prop[SDOF_LOAD_F_Y] = - spring_constant * valve_movement_y; Message("spring force = %e\n",prop[SDOF_LOAD_F_Y]); } |
