pressure can't converge with 2nd-order method

Unharuka · December 27, 2021, 12:04

Hllo everyone,

I'm using FLOW-3D HYDRO v1.0 to do numerical simulation. However I can't open second-order in Model Setup →Numerics→order of approximation. Once I open it, the simulation will show "pressure iteration did not converge" whatever simulation I do.

I used FLOW-3D v11.2 for a long time, and it works correctly. So I don't think there are any fatal errors in my setup. It confused me for a long time. Thank you very much!!!

Hello!

I have faced this issue as well and technical support at Flow-Science's technical support is aware of it. The issue should be resolved in the updated solver within FLOW-3D HYDRO 2022R1.
