Simulation only loops once in Butterfly and snappyHexMesh fails to create joined mesh #500

Open hwy280 opened 6 months ago

hwy280 commented 6 months ago

Hi folks, I am experiencing issues with a simulation in butterfly with two problems:

1) The simulation only runs for one time step and then stops, see below:

Create time

Create mesh for time = 0

SIMPLE: convergence criteria field nut tolerance 0.0001 field k tolerance 0.0001 field U tolerance 0.0001 field p tolerance 0.0001 field epsilon tolerance 0.0001

Reading field p

Reading field U

Reading/calculating face flux field phi

No MRF models present

No finite volume options present

Starting time loop

Time = 1


2) The snappyHexMesh tool fails to create a joined mesh, it seems just capturing the box alone.
