[start here] The model Im working on has Turbulent SST, Moisture transport in the air and Heat transfer in moist air as physics, and Moisture flow, heat and moisture and NITF as multiphysics couplings. Problem is when I run time dependent, one way with Initialization NIFT, if the time range is (0,0.1,1)s it gives me a result. But when I run the same model for the range of (0,0.1,1)h it says failed to find consistent initial values. I need the study to be done for (9,30[min],16)h. Can someone give me any advice?

The consistent initialization is done using a very small time step. That time step is, however, a fraction of the first time step in your simulation, which in itself as a default is connected to the total time of the simulation.
Try setting the initial time step manually.
