Hello, 

I have two questions:

1. How to view the temperature distribution for each layer?

2. what kind of equations do you use on displacement and thermal analysis in additive print?

Thanks.

Not sure about the first, but assume it's part of the post-processing functions. For the latter, it'll be covered in the documentation, if not check for references: we usually show what we've done unless it's confidential ANSYS IP.

Hello rwoolhou,

Thank you for your reply. 

1. Can I view the molten pool moving in each layer in additive print or science? 

 

2. Can you share the documentation which may contain the equation? 

Thank you.

Bo

I don't know the tools so no idea about 1) - have a look at a smaller problem and explore the interface. 

Click on "help" and review the documentation: if it's not there check for links to references, otherwise we won't have anything we can share.

Answer to: "1. How to view the temperature distribution for each layer?": 

To visualize the temperature, you should run a Thermal History analysis in Additive Science. 

Make sure you check the "Coaxial average sensor data" and specify the "Sensor radius" and the "Z Height Range" (this should be from 0 to the height of your part). 

The result is a VTK file and it can be visualized using Paraview, the temperature result consists of colored dots and the color shows the averaged temperature within the "Sensor radius" of a specific location. 

 

Answer to: "1. Can I view the molten pool moving in each layer in additive print or science? ":

You cannot view the molten pool. The closest thing to do is to run a Single Bead analysis in Additive Science, which will give you the averaged dimensions of the melt pool (length, width, height), but no visualizations.
