As will be understood from the geo file that I have first created a cube and then made a sphere inside it. I did not delete volume as size of the sphere within the cube. I am giving two different material property to the cube as well as the sphere. Will it create a problem in this case? (as I am not getting my FEM results correctly!). If yes, can you please help me how to create the desired geometry so that it can get meshed in properly. I will be thankful to you if you could please pull me out of this. Looking forward for your reply.

Your second volume has a hole, and should thus be defined using two surface loops.

I recommend reading the tutorials before sending questions to the list.
