helping about udf
Hi friends,
I have a model that rotate about x axis through passing air flow on it.(free roll) I have written an udf for this model but I don't know that is correct or not. please help me. udf is : #include "udf.h" static real wx = 0.0; static real Mx=10; static real dwx; real NV_VEC(omega); real Ix=10; DEFINE_SDOF_PROPERTIES(missile, prop, dt, time, dtime) { prop[SDOF_MASS] = 50; prop[SDOF_IXX] = Ix; prop[SDOF_LOAD_M_X] += Mx; dwx = dtime * Mx / Ix; wx +=dwx; NV_D(omega,=,wx,0,0); //omega[0]= wx; } |
