How to find Polar MI and Diametric MI in Ansys Workbench? and what is Diamteric Moment of inertia?

Deepesh, I recommend you do a search on Google to find out what Diametral Moment of Inertia is. I found this in < 1 minute.
In SpaceClaim, you must assign a Material to a solid body, then on the Measure tab, click Mass Properties.

You get three moments of inertia.

You are showing Area Moments of Inertia because you have not assigned a Material in SpaceClaim.
There are two diametral MIs, and they have the same value when the object is a disk.

The units have changed too.

Area MI in the first photo has unit mm^5 whereas it should be mm^4??
Also, is there any other name for the diametral moment of inertia?

With no material assigned, it's a volume moment of inertia and I don't care about that at all.
I only care about the mass moment of inertia that is computed after a material has been assigned.

So, its basically before applying the material, it gives Area Moment of inertia?
After assigning material, it gives diamteral MI?

No, with no material assigned, it's a volume moment of inertia.
After assigning a material, SC gives three mass moments of inertia.
