How you could make multiply forcing at the same location is as follows. In the *.ext file, define the same Quantity "waterlevelbnd" on the same polyline, e.g. twice, with different *.bc files. </p> <p>For instance, if you want to define astronomical + time series at point 0008 of polyline "Oyarvide.pli", then in the *.ext file, you can write</p> <pre> [boundary] quantity = waterlevelbnd locationfile = Oyarvide.pli forcingfile = astronomic.bc [boundary] quantity = waterlevelbnd locationfile = Oyarvide.pli forcingfile = timeseries.bc</pre> <p>Then in "astronomic.bc", you write:</p> <pre> [forcing] Name = Oyarvide_0008 Function = astronomic Quantity = astronomic component Unit = - Quantity = waterlevelbnd amplitude Unit = m Quantity = waterlevelbnd phase Unit = deg M2 0.5 0</pre> <p>And in "timeseries.bc", you could write:</p> <pre> [forcing] Name = Oyarvide_0008 Function = timeseries Time-interpolation = linear Quantity = time Unit = seconds since 2001-01-01 00:00:00 Quantity = waterlevelbnd Unit = m 295747200 1 295833600 1</pre> <p> </p> <p>Please let us know if you have any questions.</p> <p>Kind regards,</p> <p>Jing Zhao</p> <p>Deltares</p>Jing Zhao2018-07-25T16:27:04ZRE: Setting up multiple forcing on boundary conditionsMohammadreza Khanarmueihttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=641338&messageId=18325722018-05-15T04:25:28Z2018-05-15T04:25:28Z<p>Hi Sebastian,</p> <p> </p> <p>I am using the same version of D-FLOW and I've faced the similar problem regarding introducing multiple forcings at a boundary. I would be thankful if you could share your idea once you address this problem. Also, it would be much appreciated if developers could please advise in this regard.</p> <p>Cheers,</p> <p>Reza</p>Mohammadreza Khanarmuei2018-05-15T04:25:28ZSetting up multiple forcing on boundary conditionsSebastian Martijenahttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=641338&messageId=14377312018-01-26T21:31:38Z2018-01-24T16:36:14ZAccording to D-Flow FM User Manual: “A support point can have multiple forcing quantities of the same type (i.e. water level, velocity, Riemann, Neumann or discharge). These quantities are added up. This can be relevant to add a surge level to an astronomical water level for example”.<br />However when setting up 2 forcing for water level (i.e. astronomical + time series, or 2 different time series), and inspecting results after run for a nearby observation point, it seems that D-FLOW does not add both series, instead it doubles the first value stored in “WaterLevel.bc” file.<br />Is this a software bug or am I doing something wrong?<br />I'm using Delft3D FM Suite 2017 HMWQ 1.2.2.36603<br />Kind regards,<br />Sebastian<br /><br /><br />[forcing]<br />Name = Oyarvide_0001<br />Function = timeseries<br />Time-interpolation = linear<br />Quantity = time<br />Unit = seconds since 2001-01-01 00:00:00<br />Quantity = waterlevelbnd<br />Unit = m<br />295747200 1<br />295833600 1<br /><br />[forcing]<br />Name = Oyarvide_0008<br />Function = timeseries<br />Time-interpolation = linear<br />Quantity = time<br />Unit = seconds since 2001-01-01 00:00:00<br />Quantity = waterlevelbnd<br />Unit = m<br />295747200 1<br />295833600 1<br /><br />[forcing]<br />Name = Oyarvide_0001<br />Function = astronomic<br />Quantity = astronomic component<br />Unit = -<br />Quantity = waterlevelbnd amplitude<br />Unit = m<br />Quantity = waterlevelbnd phase<br />Unit = deg<br />M2 0.5 0<br /><br />[forcing]<br />Name = Oyarvide_0008<br />Function = astronomic<br />Quantity = astronomic component<br />Unit = -<br />Quantity = waterlevelbnd amplitude<br />Unit = m<br />Quantity = waterlevelbnd phase<br />Unit = deg<br />M2 0.5 0Sebastian Martijena2018-01-24T16:36:14Z
