Inflation - Airfoil Meshing - Divergence problem

I have been doing some simulations with vertical axis turbines in Fluent. In order to achieve good results I have tried using the Inflation option in Ansys Meshing module around the different airfoils in the turbine. But I found a problem in Fluent that says: 'Divergence detected in AMG solver'. When I disable the Inflation option the problem disappears.

I have tried different meshing methods as quadrilaterals and triangles as well as refining the mesh using sphere of influence around every airfoil, but still I haven't found a proper solution to the divergence error.

Thanks in advance and best regards.
