open TELEMAC-MASCARET The mathematically superior suite of solvers

I am trying to do a coastal inundation modelling using TELEMAC-2D for the Mocha cyclone which has made a landfall at Myanmar on 7th May, 2023. In this i need a better Case file for my simulation. Could you please anyone suggest me a better case file key words. Here with I attached my case file (.cas), geometry (.slf) and boundary condition file (.cli). Here i need to increase my water level to validate my model. please anyone help me!

I could not able to upload the Geometry file because its having the huge data



I attached the water level data in my result

Hello,

You can have a look at $HOMETEL/examples/tide/t2d_tide-pressbc.cas steering file, in particular the following keywords:
- tide keywords,
- atmospheric pressure + wind keywords,
- atmospheric data file,
- ATMOSPHERIC PRESSURE AT TIDAL BOUNDARIES = YES (Inverted barometer method)
and read the TELEMAC-2D user and TELEMAC-2D reference manuals.

In your steering file:
- do not use VARIABLE TIME-STEP = YES with Finite Elements, it generally does not work correctly in TELEMAC-2D (but with Finite Volumes it does),
- if you activate FREE FORMAT FOR ATMOSPHERIC DATA FILE, you have to implement something by yourself. I would recommend to provide a file format compatible to what already exists in openTELEMAC,
- if you change defaul values, you should know why:
- e.g. SOLVER ACCURACY = 1.E-3 may be too relaxed (if too coarse, the convergence may be not reached),
- INITIAL GUESS FOR H = 0, why?
- COEFFICIENT OF WIND INFLUENCE (if you let default value for COEFFICIENT OF WIND INFLUENCE VARYING WITH WIND SPEED, this value is useless).

Hope this helps,
