run a Poiseuille case using inletoutlet conditions

ccciew

March 2023 in DualSPHysics v5.0

How could I run 2D Poiseuille case using inletoutlet conditions? I tried to give conditions as follow:

Here, rectang.stl, rectang_pre.stl, and rectang_house.stl are as follow:

The solid-color region is rectang_pre.stl, while the blue one is rectang.stl, and the red one is rectang_house.stl.

I designed rectang_pre because it reports an error when the inlet is close to the mkbound.

The simulation domain is 2D, as you can see from Figure 1. And the inletoutlet conditions is given as:

But the result (velocity) is seem wrong:

Could anyone tell me why? Thanks a lot.
