- Maximum size of the domain should be 2-3 times wavelength - Resolution; dp should be H/10 being H wave height. - In the XML you should use: coefh value="1.2 to 1.5" StepAlgorithm value="2" Kernel" value="2" ViscoTreatment value="1" Visco value="0.01" ViscoBoundFactor value="0" DeltaSPH value="0"
I have a question about the maximum size of the domain, in the C.Altomare's paper(2015). A 35m wave tank was modelled and good agreement was obtained with theoretical results, how to account for it, thank you.
Yes,it is. I established a wave tank with length 35m,parameters setted as above, there are many particles out ,which was beyond my expectation. Can you help me take a look at it?
Sorry rieck I can not see you parameters Note that this case is the same as provided in the package!!! You only have to follow CaseWaves_REG. But once again you have to create only wave tanks of 2-3 times the wavelength... we created a tank of 35 m but we only compute wave heights at x=2m
Hi Consider we want to measure Pressure at this problem of wave propagation. 1) By setting DeltaSPH value="0", then Pressure OSCILLATION occurs. 2) Is it better to use "laminar+SPS" instead of "artificial viscosity"?
If you want to measure pressure then, you can use DeltaSPH. Please read the guide about DeltaSPH where advantages of disadvantes of our implementation for simulating wave propagation is described
I'm new to DualSPHysics, from the previous comments may I consider defining my domain as 1/10th of the actual domain ? if wave height, wave length and Depth are 3.5m, 112m and 17m, shall I consider them as 0.35, 11.2 (Tank size of 35m) and depth 1.7m?? similarly do we need to calculate other parameters like Tp, viscosity etc., ?
Further, Any video tutorials for creating the domain ?
Hi Alex I want ask for wave propagation case can increased coefh for more than 1.5?because I was used for case with domain more than 2-3 times and I used coefh = 2 but result still have discrepancy with experiment. is there any limitation for coefh for use in wave propagation case?
