Hello friends,
I am new in this forum, I am trying to simulate the piston type wave maker for water tank. I have generated the code for the sinusoidal motion for the left wall of the tank. But while I interpret the code in ansys fluent I am getting some parse error in line 10. I Tried but failed. Please can you help me to resolve my issue. Thanks in advance #include<stdio.h> #include“udf.h” #define A 0.07 #define pi M_PI #define LW 8 #define g 9.81 #define h 6 #define L0 40.0 #define L1 60.0 DEFINE_CG_MOTION(piston_moving, dt, cg_vel, cg_omega, time, dtime) { real u = 0; real ww = 0; real kk = 0; real S = 0; real cc = 0; real T = 0; kk = 2.0*pi/LW; cc = sqrt(g*tanh(kk*h)/kk); /*wave velocity*/ ww = kk*cc; /*circle frequency*/ T = 2.0*pi/ww; S = 0.5*A*(2*kk*h+sinh(2*kk*h))/pow(sinh(kk*h),2); if(time <= T) { u = ww*S*time*cos(ww*time)/(2*T); cg_vel[0] = u; } else { u = ww*S*cos(ww*time)/2; cg_vel[0] = u; } } |

I'm also working on something similar. I wanted to know how you're adding the mass of the plunger and whether you're using overset meshing. Would be of great help if you could let me know.
