I have succeeded run the online analysis.. But I
prefer export the map file to .mat and use harmonic analysis using
t_tide to produce co-tidal.</p>hani ramadhan2019-03-08T03:09:17ZDefining Neuman BC based on offshore forcinghani ramadhanhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806675&messageId=22009692019-02-28T13:17:26Z2019-02-28T13:17:26Z<p>Dear everyone,</p>
<p>I want to simulate tidal propagation at my domain that has three open
boundaries. I want to use water level boundary for north boundary and
Neumann BC for the west and east boundary. But I don't know how to
specify the gradient of waterlevel. I have tried to set the gradient
time series as 0, but in cophase plot, it doesn't show propagation.
Would you please give some advice and may be the example of
calculation Neumann BC based on offshore forcing. Thanks a lot.</p>hani ramadhan2019-02-28T13:17:26ZRE: Compute Co-tidal Using Online Fourier Analysishani ramadhanhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806675&messageId=22009432019-03-08T03:09:17Z2019-02-28T13:10:49Z<p>I'm sorry I misunderstood what does n-th constituent mean. So to do
fourier analysis we have to define the time for analysis, the 1st
constituent will have the same period as the time simulations, and the
2nd constituent's period is half of the analysis period and so on.
Alternatively, we can use harmonic analysis using t_tide by looping
the process through all grid in our model.</p>hani ramadhan2019-02-28T13:10:49ZCompute Co-tidal Using Online Fourier Analysishani ramadhanhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806675&messageId=21617432019-03-08T03:09:17Z2019-02-04T08:42:03Z<p>Dear all,</p>
<p>Is it possible to generate co-tidal using online fourier analysis?
Can it be visualized using quickplot or gpp?</p>
<p>I have read the appendix about .fou file that is the input file for
online fourier analysis, but I still don't understand what n-th
consituent in mdf mean? Should I activate the tidal process for this?
How can I define the n-th constitent in mdf file?</p>
<p>Thank you for your help..</p>
<p>Best regards.</p>hani ramadhan2019-02-04T08:42:03Zincoming flow : zero concentration gradient of incoming flow.hani ramadhanhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806675&messageId=21251452019-01-16T08:28:35Z2019-01-16T08:28:35Z<p>Dear all,</p>
<p>Is that possible to define zero gradient of concentration at open
boundary so that the concentration of active substances will have the
same number with ambient concentration? I need this because I don't
have data about incoming flow concentration for some active
substances. I really need advice about this.</p>
<p>Thanks and best regards</p>
