I like to melt a steel component by using temperature alone in abaqus and need to capture the displacement of those component so, what kind of analysis shall i use in abaqus to proceed further?
It would be helpful if you could provide more information about the analysis. For example, are you most interested in the solid part or the fluid part?
Abaqus/Standard analyses are of solid parts. Some analyses (e.g. analyses of welding) approximate the molten region using low strength and stiffness, but this approach will not correctly predict the motion of material in the weld pool. The method is used to make sure that the weld pool has the appropriate level of stiffness.
Alternatively, the Abaqus/Explicit Eulerian option can be used to simulate fluid flow.
