Flow over an elastic mounted cylinder in Ansys fluent
Hi there,
I am trying to simulate vortex induced vibrations using Ansys fluent at Re=100 using the following udf for 6DOF solver: #include "udf.h" DEFINE_SDOF_PROPERTIES(viv, prop, dt, time, dtime) { real cg; real k = 1.578; cg = DT_CG(dt)[1]; prop[SDOF_MASS] = 1; prop[SDOF_LOAD_F_Y] = -k*cg; prop[SDOF_ZERO_TRANS_X] = TRUE; prop[SDOF_ZERO_ROT_X] = TRUE; prop[SDOF_ZERO_ROT_Y] = TRUE; } When I simulate this, it gives me very large lift coefficient(~100-200) and the cylinder also oscillates very rapidly. Can some please help? |
