Hello hone ,
Ansys Fluent cortex error could happen because of the following reasons.
1. Please check whether your case is 2d or 3d some times 2d sheet geometries in 3d mode can cause this error.
2. It can also happen if you save your workbench file in another folder and not in the same folder of fluent root directory. Please check on that.
Thanks
Chaitanya Natraj
