Wave Generation
hi all,
I am using the template case file CASEWAVEMAKER. I want to generate regular waves with H=0.1m and T=1.3s. In the xml file, the motion of the piston is defined, however I am not sure what vales i should put in for some of the parameters.
Example in CASEWAVEMAKER:
motion
objreal ref="10"
begin finish="100" start="0" mov="1"
mvrectsinu next="2" duration="5" id="1"
freq z="0" y="0" x="0.5"
ampl z="0" y="0" x="0.25"
phase z="0" y="0" x="4.71238898"
mvrectsinu
What the values of the freq, ampl and phase can be for H=0.1, T=1.3s waves? And how can I work that out? This is probably a silly question......
Thanks

Solutions for you now:
- use software that computes the stroke and frequency of the piston to create the desired waves or use online applications from: http://www.coastal.udel.edu/faculty/rad/wavetheory.html
- new release of DualSPHysics, version 4.0 will include automatic wave generation with H,T,d as input and then stroke of the piston is automatically calculated for regular waves and irreguar spectra

Thanks for the detailed answer. It helped me a lot !
