Mystic error in FLUENT Solution initializtion

Hi .. I created the attached geometry mode in GAMBIT and exported it in ".msh" format.
I first created the geometry as is in the pic below (Only the part above the axis .. its an axisymmetric case)
it worked 100% right....got the results....
2nd time I tried it constructing in the vertical orientation as shown below:
I gave the same BCs .. axial vel etc ..but got the following weird symbols in the initialization :
I tried to initialize manually by putting the inlet value in the initialization boxes.. but it gives "Divergence detected in AMG solver .. (for all equations if i try to change the cycle type and stability method in solutions - advanced options"
(Its v imp for my project ... after having worked so much and coming to the end of writing a huge UDF for vertical case i have come across this error! . NOTE : no udf was loaded in the above case i mentioned..its later part

It is very well documented in FLUENT documentation:
// User's Guide :: 2 // 5. Reading and Manipulating Meshes // 5.2. Mesh Requirements and Considerations // 5.2.1. Geometry/Mesh Requirements
"Axisymmetric geometries must be defined such that the axis of rotation is the x axis of the Cartesian coordinates used to define the geometry"
