Error: forrtl: severe (157)-Flow cannot pass through fan/impeller component
 

Hi everyone, I'm using Flow3D-v12 to simulate the air flow passing well-turbine in Oscillating Water Column.
I'm using fan/impeller component to represent well turbine.
Pipe: radius=0.3m, Length=1.1325m
fan/impeller object properties: outer radius=0.3, Spin rate=209.44 rad, Accommodation coefficient for rotational velocity Ad=987 1/s, Axial velocity coefficientBd=0, number of blades =8, thickness=0.13125m. Fan located at x=0.49m from inlet.
As we know, fan/impeller component is treated as phantom component. However, The result shows the flow cannot pass through this object in my simulation and there is an error:
forrtl: severe (157): Program Exception - access violation
Could you please give me advice about this problem?
Thank you
