What is causing error for inlet boundary condition?

Hello,

I am new to Simscale and my aim is to replicate an incompressible flow study to compare drag coefficient values. The original study: “(Huang et al., 2007) Numerical evaluation of wind effects on a tall steel building by CFD”
Here is the link to the project where I am attempting to recreate the above study: SimScale

When trying to run the simulation, I am getting the following error: “The simulation contains only outlet boundary conditions, which will most likely lead to global continuity errors. Please select an additional inlet boundary condition or make sure that at least one custom boundary condition behaves as an inlet.”

I have checked the boundary conditions documentation, and implemented the velocity profile, k and epsilon values based on this tutorial: Smoke Propagation From a Chimney | Tutorial | SimScale

Can someone let me know how to resolve the error? Any help is appreciated.

Hello, thanks for reaching out in the forum.
This is just a warning if you have set up the simulation correctly as stated in the tutorial you should be good.
Let us know if your simulation is running succesfully.

Best regards
Sebastian
