Good day everyone,
I am new to fluent and make a simple simulation.
I can get correct temperature distribution and pressure on fluid domain.
On the solid-fluid conatact faces, I can get the pressure on fluid-side, but no data on solid-side.
Could any one explain the reason for me and teach me how to fix the problem?

Best regards,
ZHU

pressure is calculated only in fluid region, not in solid
make a sketch if you still have questions

Thank you for your information.
As in the picture, on the contact face of solid-fluid, pressure only available on fluid side.
What I need is to tranfer the water pressure to static structurals as a load.
And I found the static structrual do not work with fluid (I think the reason is fluild material do not have elastic properties). So I need to surpress the fuild domain. Then I need the pressure on the solid face which contact with fluid.

Best regardings,

As AlexaderZ mentioned, the pressure will only be calculated in the fluid domain. The pressure on the outer surface of the fluid domain, in contact with the pipe, will be the pressure on the wall of the pipe. You can export this value in a few different ways.

First, you can plot a contour on the interface wall between the fluid and solid domain. This will show the pressure at the interface.

contour>new>pressure contour @ interface wall

You can export this pressure to a csv by going to:

File>export>profile

Select the interface wall, select pressure, and export the csv.

For a simple model, you can make an assumption of the pressure by averaging over the surface. To do this go to the results tab, select surface integrals, select area-weighted-average, pick you interface wall, and select static pressure. This will give you a single value for the average pressure at the wall which can be easily set as a load in static structural model.
