Inlet: Element 'gridresetvelz' is invalid

barry · June 2021

I am trying to generate waves via imposing velocity in the buffer zone using 'mode 3: interpolated velocity' as shown on page 17 of XML_GUIDE_INLETOUTLET.pdf .

Following @iarba27 's suggestion

Dear Barry,
you can either use a uniform velocity profile or imposed velocity that varies with the depth. In that case, as a_meduri2312 mentioned, you can impose velocity but use interpolate option. My advise is to construct the velocity file using at least 11 points (dividing the water depth by 10). The lowest one corresponds to the fluid bottom, hence vel=0. The highest one is on the still water level. It would be better if your file has the following structure (see picture).

I create my XML and external mesh for imposing velocity:

<imposevelocity>:

 <imposevelocity mode="3" comment="Imposed velocity 0:fixed value, 1:variable value, 2:Extrapolated velocity, 3:Interpolated velocity (default=0)">
     <gridveldata file ="u_vel.csv" comment="CSV file with velocity data in different times and positions" />
     <gridresetvelz value="true" comment="Reset Z velocity after interaction (default=false)" />
     <gridposzero x="0" z="0" comment="Defines position of grid (default=0)" />
 </imposevelocity>

external mesh u_vel.csv :

However, I got the error:

*** Exception (JXml::ErrReadElement) at ..\source\JXml.cpp:231
Text: Error reading xml - Element 'gridresetvelz' is invalid.
File: T6_out/T6.xml(row:90)

I am not sure where it went wrong. Any suggestion is greatly appreciated!

Many thanks!

Your apostrophes might be wrongly placed. gridsetvelz is in red which means it is inside a quote that is not properly closed.

Hi @a_meduri2312 , sorry for the late reply. I checked several times, the apostrophes were right, and the red is due to the code color in the forum. Do you have any other insights? Thanks!

Hi Barry,

Can you share your xml and velocity files so that we could take a look at them?
