Long waiting time for large number of gauges

Ni Niels,
I have trouble getting wave2Foam to run with large amount of gauges ("surfaceElevation" function object) in the domain. Previously, I usually use small amount of gauges in my domain. This run almost instantly without any problem. However, it I increase the amount of gauges (say to 5000 gauges), and run waveFoam, the simulation spent alot of time before entering the time loop as follows : Code:
Reading g Reading waveProperties Reading waveProperties Reading field p_rgh Reading field U Reading/calculating face flux field phi Reading transportProperties Selecting incompressible transport model Newtonian Selecting incompressible transport model Newtonian Selecting turbulence model type laminar Calculating field g.h No finite volume options present time step continuity errors : sum local = 0, global = 0, cumulative = 0 DICPCG: Solving for pcorr, Initial residual = 0, Final residual = 0, No Iterations 0 DICPCG: Solving for pcorr, Initial residual = 0, Final residual = 0, No Iterations 0 time step continuity errors : sum local = 0, global = 0, cumulative = 0 Courant Number mean: 0 max: 0 Starting time loop <<<< Really long time here >>>> Courant Number mean: 0 max: 0 Interface Courant Number mean: 0 max: 0 deltaT = 0.0011999956 Time = 0.0012 MULES: Solving for alpha1 Kind regards, katakgoreng |

Good evening,
It has been some time since my last reply, so I will try to wrap everything up: @Katakgoreng: I have never tried to use that many wave gauges. Could you please try to track it down in order to figure out, where the time is spend? E.g. put some Info statements in the code. Kind regards, Niels
