How to measure pressure？

How to measure the pressure at a certain point in a dam failure case？

[janbender]

Some pressure solvers (e.g. WCSPH) compute the pressure for all partices, some others do not directly compute a pressure value. For these methods you would have to implement something to get this info.

Finally, you can export the pressure data by using the scene setting "particleAttributes ":

感谢上述回答，
我在场景文件中添加了 "enablePartioExport": true,和"particleAttributes": "velocity;density"但是只输出了 partio文件夹，没有输出particle文件夹

Can you please write in English?

Thank you for the above answer,
I added "enablePartioExport": true and "particleAttributes": "velocity; density" in the scene file, but only output the particle folder, not the particle folder
Can this method output the pressure at a specific location？

[duanlinlim]

I found in the GridModel_Sender2019.json file that "particoAttribles": "velocity" was added instead of "particleAttributes": "velocity", but no matter which one it is, there is no output from the particle folder

Why did I press the 'l' key in Hotkeys, but there was no response and the particle information was not printed out

[janbender]

The hot key is "i".

If you enableVTKExport, particle files are exported which can be imported in ParaView. They contain all fields which are specified by "particoAttribles". To see which fields are available you can take a look at the tab "FluidModel" and see which options you have in the box "Color field".

I would like to ask if it is necessary to select particles when printing particle information. Is it too blurry to circle particles directly on the GUI interface with the mouse,
