Ansys Fluent: False Gear Pump With Dynamic Mesh: Setup

Simulation of a 2D gear pump using the dynamic mesh method. In the video you can see that the gears do not touch each other, obviously this is not physically possible, hence what i mean by “false“. The contents of the UDFs are: UDF1: #include “udf.h“ DEFINE_CG_MOTION(gear_1_new,dt,vel,omega,time,dtime) { real t = CURRENT_TIME; NV_S (vel, = , 0.0); NV_S (omega, = , 0.0); omega[2] = 60.0*(1-0*exp(-500000.0*t)); } UDF2: #include “udf.h“ DEFINE_CG_MOTION(gear_2_new,dt,vel,omega,time,dtime) { real t = CURRENT_TIME; NV_S (vel, = , 0.0); NV_S (omega, = , 0.0); omega[2] = -60.0*(1-0*exp(-5000000.0*t)); } These are to set the motion of both gears. #Ansys #AnsysFluent #CFD #AutoDeskInventor
