Consistent error while computing the results for the model built

Please login with a confirmed email address before reporting spam

Sir..

I am working on a building model with pipes embedded in the ceiling for Concrete Core Cooling. I am getting a continuous error even after many corrections. The error says

Failed to find consistent initial values.
Last time step is not converged.

I have made the corrections suggested by you in the above comment. But still, the problem persists. I request you to have a look of the model in the link and help me out if you can find any errors rolled out.

Thanking You sir...

Hi

complex multi-physics models can be tedious to get running, particularly when you start from all default "0" initial conditions, mixing HT and CFD. One way is to use a stationary solver to set the initial conditions, then run a time series from there

Good luck
