How to simulate the process of laser overlapping deposition
Hi, everyone.
I am a new user of COMSOL. Now, I want to simulate the temperature field of laser overlapping deposition. This is a additive process in which material is added continously. I don't know how to model the additive process.
I wish to get help here.

Re: How to simulate the process of laser overlapping deposition
May be, I have not presented my question clearly. What puzzle me is how to build the model in which the materials is added continuously. In other word, how to increase the domain of laser-depostited part.
Thank you.

Re: How to simulate the process of laser overlapping deposition
Hi
adding material (or changing the topology) is a tricky domain ;)
It's not easy to start with, almost a full time project by its own.
I would suggest that you look at the "level set method" or the optimisation examples. As there are ways to approach material adding or removal by playing with the local material properties and boolean functions on them

Good luck

Re: How to simulate the process of laser overlapping deposition
Hi, Ivar. Thank you very much for your suggestion. Now, I am going to adopt the way of controling the properties of materials.
Wish you everything to be going well.

Re: How to simulate the process of laser overlapping deposition
Hi,
Have you solved your problem?
I try to use the ALE to present the material removal, but fail.
Could you give me some advice and guidance?
Thanks in advance for your help.
Best wishes to you and your family.

Re: How to simulate the process of laser overlapping deposition
Hi, Ivar
very brilliant help. I am still puzzle with the method you mentioned-the change of the local material properties. I know how to change the material properties with temperature (if in the heat transfer model). if only change the properties, the heat source-material interaction interface do not change. while actually, if there is material removal or adding the interface should move according to some quantity relative to the dependent variable(T -if in the heat transfer node). you also mention the Boolean function, the Boolean is only applicable to solid (am I wrong?). Could you give me a more detail?
Thanks in advance for you guidance.
Best wishes to you and your family.

Hi
Check the doc and the model of the "loaded elbow" in the model library, its "solid/structural" but from my point of view also applicable, by similarity to HT
