Hi @AsimUdel,
Did you change any of the input parameters from the original tutorial file by @rybchuk, other than switching TurbineFastDisk to TurbineFastLine?
One thing that might be an issue is that you are using a larger timestep than recommended for ALM simulations. Typically the dt for actuator line runs might be 0.01 to 0.02 seconds, and the current dt=0.125 seconds might be more suited for actuator disk runs. This is not because of a CFL limitation, but more related to how fast each blade is moving per timestep.

Hi @lawrenceccheung , great question, I did not change any other input parameter, just switched from TurbineFastDisk to TurbineFastLine, and thank you for the valuable information regarding the dt for FastLine (ALM) case, I will keep that in mind.
