As shown in Figure \ref{842728} we can observe the largest error at the center of the uniform heat source, the relative error of the complete results is approx. R = 11 %. This value is reasonable concerning the approximation used in these simulations.  The maximal error is R = 21 % which around the maximal temperature of profile.   
 

Examples of heat transfer simulations in AM

In this section, we describe several examples of heat transfer simulations in AM modeling.
Example 1 is a comparison between the FEM model implemented in Abaqus and in-house heat transfer program (name). The main difference is that an in-house program has sophisticated "chimera" mesh capabilities and handle the adsorption of the laser beam in powder and bulk with sophisticated models. 
The first example of the heat transfer in AM is given by single track modeling. In Figure \ref{940315} we present the mesh used to model the heat transfer for the single track experiments.
