Unrealistic temperature curve for manual clustering in the DED simulation

    • Jonas S

      I have a problem with mapping the temperature curve in the DED process (Mechanical). As described in this ( discussion, the thermal analysis does not seem to map the temperature correctly. 
      However, I have now simulated the same model with Gcode clustering (instead of manual) and the temperature curve is much more realistic. The picture shows the two variants in comparison (Gcode above, manual below). 

      I therefore suspect that there is a problem with the contacts between the individual bodies of the part geometry (manual clustering). After the geometry selection, the wizard directly creates contacts (compound) between the superimposed surfaces of the individual bodies, but this does not seem to be sufficient.
      So my question is, how should these contacts be adapted so that a sensible temperature curve can be achieved with manual clustering? 

      Thanks in advance

      Hi Jonas,

      Please see if the following post looks relevant: Workbench DED simulation manual clustering (
