Ansys Fluent: Flow Around A Mechanically Controlled Door.

This video shows how to set up the simulation for a simple controlled mechanical door on a flow of water, the door can rotate around its lower extreme; so is being pushed by the water, and when its angle reaches a critical value, a torque is applied on it to return the door to its original position. #include “udf.h“ #include “math.h“ DEFINE_SDOF_PROPERTIES(Moving_wall, prop, dt, time, dtime) { prop[SDOF_MASS] = 1.0; prop[SDOF_IZZ] = 0.1; prop[SDOF_ZERO_TRANS_X] = TRUE; prop[SDOF_ZERO_TRANS_Y] = TRUE; prop[SDOF_ZERO_TRANS_Z] = TRUE; prop[SDOF_ZERO_ROT_X] = TRUE; prop[SDOF_ZERO_ROT_Y] = TRUE; prop[SDOF_ZERO_ROT_Z] = FALSE; real ang = DT_THETA(dt)[2]; real ang_vel = DT_OMEGA_CG(dt)[2]; real moment_z = 0; if ( ang GOET 4.0 * / 9.0 - / 2.0) { moment_z = 0; } else if ( ang LOET / 9.0 - / 2.0) { moment_z = 0.8; } else if (
