This way no minimum value is applied. You can find it in the FLOW GUI on the Output screen as 'Export WAQ input', or 'Online coupling for WAQ' in older versions.<br /><br />MichelMichelle Jeuken2015-06-03T08:49:10ZRE: VolMin for Hydrodynamic couplingQinghua Yehttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806765&messageId=4076952014-04-02T07:49:04Z2014-04-02T07:49:04ZHi Martin,<br /><br />What Michel means is: change the line in hyd file manually from:<br />"1.0 *** volumes smaller than 1.0 are reported" to<br />"0.01 *** volumes smaller than 0.01 are reported".<br /><br />But you have to keep in mind every time when you got a new hyd file. Don't forget.<br /><br />Hope this solves your question.<br /><br />QinghuaQinghua Ye2014-04-02T07:49:04ZRE: VolMin for Hydrodynamic couplingRudy Schuederhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806765&messageId=4073892014-04-01T14:03:43Z2014-04-01T14:03:43ZHi Michel,<br /><br />I think you are correct and that I misinterpreted the message in the coupling report. Just one last thing. You say:<br />"1.0 *** volumes smaller than 1.0 are reported<br /><br />There you can change it before you run the coupling."<br /><br />How should I go about changing it? Should I simply delete the line in the file?<br /><br />Thank you!<br /><br />MartinRudy Schueder2014-04-01T14:03:43ZRE: VolMin for Hydrodynamic couplingMichelle Jeukenhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806765&messageId=4050422014-03-27T10:01:42Z2014-03-27T10:01:42ZHi Martin,<br /><br />The minimum value is not hard coded in the coupling program, but the GUI always writes the same setting. It is possible to interfere with it. After writing the input from the coupling program, you wil see that there is a settings file created named couplnef.inp. In it you will see a line saying:<br /><br /> 1.0 *** volumes smaller than 1.0 are reported<br /><br />There you can change it before you run the coupling.<br /><br />However, if you do not change it, you should still have a hyd file, only the volumes are set to a minimum value of 1. Are you sure that you see an error, and not a warning?<br /><br />MichelMichelle Jeuken2014-03-27T10:01:42ZVolMin for Hydrodynamic couplingRudy Schuederhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806765&messageId=4043432014-03-26T01:47:56Z2014-03-26T01:47:56ZHello,<br /><br />Just a quick question: when I am creating my hydrodynamic coupling file from a FLOW .com file, it fails to produce the .hyd file because of the error "Volume is less than VolMin ( =1 m3)"<br /><br />Is there any way to decrease this value of VolMin or is it rigidly built into the program? I am modelling in 3 dimensions and am hoping to have a spatial discretization of less than 1 m3. My velocities are on the magnitude of 1.4 e^-7 m/s and my time step is about 1 second so the courant criterion would not be compromised to my knowledge.<br /><br />Thank you!<br /><br />MartinRudy Schueder2014-03-26T01:47:56Z
