Here is the tutorial and the file I used.

1. Step 1:

   Start SolidWorks.
   

   

2. Step 2:

   On Front plane in part mode make a sketch like this using spline.
   

   

3. Step 3:

   Extrude it by height say 50mm.
   

   

4. Step 4:

   Again enter front plane >> sketch and again a spline like this. And have a coincident relation with the end point of previous spline.
   

   

5. Step 5:

   Extrude it by 50mm also.
   

   

6. Step 6:

   Under surfaces tab choose fillet.
   

   

7. Step 7:

   Select face fillet type.
   

   

8. Step 8:

   For face set 1 select extrude-surface 1 and for face set 2 select extrude-surface 2. adjust direction to inside region.
   

   

9. Step 9:

   Choose front view for better view of the fillet to be formed.
   

   

10. Step 10:

    Click fillet options in fillet property manager.
    

    

11. Step 11:

    Check curvature continuous. And you can see the change in fillet.
    

    

12. Step 12:

    Change the fillet radius to 20mm.
    

    

13. Step 13:

    Click OK and the fillet is formed.
    

    

14. Step 14:

    Under Evaluate tab choose zebra stripes for tangency analysis. And zoom to the surface along the surface-extrude1 and the fillet. You can notice the continuity of zebra stripes.
    

    

15. Step 15:

    Same goes for surface-extrude2.
    

    

16. Step 16:

    Disable zebra stripes and you are done.
