What is the main reason for this prompt to came when a simulation is being done on FLUENT
Try refining mesh
y+ value at the wall to be specific
30-300 - if u r using wall functions
0.1-1 if u r using mesh in the laminar sub-layer
Can anyone help with software to combine images and make a video? I have continuous images of CFD simulation and I want to combine them as per order.
