Could you please help me to run sandbox-fm?

[lj-cug]

Dear Developers:
The sandbox-fm is an interesting tool to show the hydrodynamic model running. Now I have installed it and try to run it. After checking the source code, I have several questions to consult with you.
(1) Now I have replace the Kinect v1 API getting depth and RGB video data with Kinect v2 APIs. sandbox-fm can run for "sandbox-fm record" and "sandbox-fm anomaly"
(2) In " calibrate.py", the two functions def uv_matrix() and def xyz_matrix() contains some numbers to rotate and translate coordinates. Should I modify the numbers in my case running after re-calibrating my Kinect 2.0 camera?
(3) When I run "sandbox-fm calibrate", I cannot obtain my calibration.json. Is there any more detailed information about the calibration process about sandbox-fm?
(4) The code of Dflow-fm is not open and I can download Xbeach model. So do you have the tutorial files to run Xbeach in sandbox-fm? I know the Barrier Island case in one paper.
