open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear
I am doing a simulation of TPXO in the mersey estaury in England i am having a problem with wiggling of water level
Moreover, the program seems to not read from database i set the boundary condion in open see as 5 6 6 and other is 2 2 2
*ZONE NUMBER IN GEOGRAPHIC SYSTEM FOR eNGLAND I fould out its 29 but not sure




i have attached my cas file so if any one could help me by any sugestion?
thank you

Other thing i think the TPXO file name in my computer is ''h_tpxo7.2'
i think it is wrong to write it in this formula in CAS file
should it be follwed by data of simulation (112007) which is the november of 207 year?

Hi,

First thing is that you should give the complete path of TPXO files
for example
BINARY DATABASE 1 FOR TIDE = '/home/pathtoTPXPO/h_tpxo7.2'
BINARY DATABASE 2 FOR TIDE = '/home/pathtoTPXPO/u_tpxo7.2'

For England I think there are two zone, one to the West 0 degrees it is
30 (6 W - 0W) and to the East of 0 it is 31 (0 E - 6 E), zone number 28 indicates 18 W - 12 W, so check in which region you data is falling and give the zone correctly, incorrect zone can lead to inappropriate forcing being taken from the TPXO model.

You also need to check as whether the coordinates are in UTM or geographic system, if the coordinates are in geographical coordinates then
GEOGRAPHIC SYSTEM should be 1, if they are in UTM then GEOGRAPHIC SYSTEM should be 2. You can verify/convert the data coordinates by using program which support GIS/UTM data conversion.

I use a perl package Geo-Coordinates-UTM from search.cpan.org/~grahamc/Geo-Coordinates-UTM/UTM.pm, which should be used in the perl program. There is also a python program (convertUTM.py) in script folder of telemac source code directory which can help in similar conversion.

I did not understand you question

Thank you for replay
yes it seems that mersey domain has to be extended in to larger to get the write grid !!!
thank you againe
