Thanks for making such an amazing tutorial ❤️.

Brilliant! Thank you so much for this ❤.

Very helpful tutorial! What to do if the heat source is to be used for volumetric heating and not surface?

Hi thanks for the video I have a doubt that is there any relation between welding heat input and source power intensity in the moving heat source extension

Hi thanks for the video. Can I use this same case for a dissimilar Friction Stir welding simulation?? If yes then how

Can we use this for waam simulation? Please let me know

How did you calculate the element size?

Thanks for the video Can I link this to a FLUENT simulation that includes the data on my airflow?

Hello, I work on my master thesis and am a novice in CAD and FEM. I try to simulate ultrasonic metal welding process but currently stuck with boundary conditions. The main problem at the moment is that I cannot apply the vibration motion to my system. In ultrasonic welding an upper metal sheet slides along the x-axis on top of another one with a frequency of 20 kHz. In some paper I found a formula: Ux = Xsinwt, where X is the amplitude of vibration (27.5 micrometers). E.g., upper sheet first goes to the left direction, then returns to the initial position, then goes to the right direction and so on. w = 2πf , f is 20 kHz. Welding time in the real process is about 1-2 s, but for saving computational time it could be 0,1 s in Ansys for the beginning. So I need to apply this equation in Ansys as a displacement. Perhaps it usually applies with APDL but do not understand how.

How to apply current and voltage as a process variable in moving heat source?

how do you get the laser to stay on throughout the run. mine turns on and then off and then on

Nice demonstration. Can you make one video for elements birth and death in workbench

what is that additive wizard extension?

Hi, is it possible to do multiple pass of the heat source? What parameter should I change to make this?

Hi there. Thank you so much for your video. By any chance, do you know if it is possible to apply a line shape-moving heat source instead of a circle heat source? Thank you.

hi, when i press the solve, there is an "invalid Assignment" error, at the temperature and total heat flux part, red box appear on the result section for both

WHAT IS THE VERSION OF ANSYS REQUIRED TO INSTALL THIS EXTENSION??

when i use a small spot size the laser does not stay on at a constant rate. how do I stop this happening

hey can you also make a video for Moving pressure loads....i have a presentation on monday can you please help thank you!

The extension did not work for me .can you hep me? Currently I am using ANSYS 2019R3

why heat soruce is perfectally circular

Hello, I have tried to download the Moving Heat Source Extension from the store, however, they say that downloads and purchases are unavailable at the moment. Would you kindly share with me the file you downloaded.? Thank you in advance.

Can u provide extension file

Hi!! Nice video!! I have a doubt, when you select the path in 'moving heat flux' you only can select the line which separate the 2 workpieces, but for example I need to select a particular path, which It's in the middle of a geometry (a weld bead). So I've made a 'path' with 'construction geometry' inside the model, but then in the options of the path (in moving heat flux) I can't select this path because the options are only 'geometry selection' or 'named selection' in the 'scoping method'. How can I select the path that I want? thankss!!

Hi Ángel Artero Real, Unfortunately this is one of the limitation of this plug-in. Like all the regular boundary conditions that we can add, the "path" of the "moving heat flux" has to either be chosen from a "named selection" or a "geometry". Creating a path using the "construction geometry" is a very useful tool for examining the results at a specific location but to my knowledge, it cannot be used to define the scope of the boundary condition such as in this case the path of the moving heat flux. I would suggest if you can, constructing your geometry as shown in the video, where the path separates the work piece. To my knowledge this is the best (unfortunately the only) way to do it using this particular plug-in.

@@theengineeringguide8332 Perfect, I will try another way, maybe in APDL mode... Thank you for the answer!!

Fist of all, thank you for the demonstration. When I use more than two heat source, it just simulate two of them. For istance, I used 10 heat source but ANSYS simulated only last two. Do you have any solution for that?

Thank you for your great video, it helped me out a lot. Somehow for me there are no units shown at the details of "Moving Heat Flux". Is it possible to somehow make the units appear?

Do you mean, you cannot see the units when defining the velocity and power intensity of the beam?

@@Schausteller-ni7mg This is a very weird situation... My suggestion would be to verify the download and the installation into plug-in page. Note that on the website it says the extension can be used for ANSYS version 17. Currently I am using 19.2 and it seems to be working correctly but if you are using an older version you may run into problems. As I typed this something came to mind. Are you using imperial units on your geometry/meshing modules? It is possible that the plug-in was written specifically for SI units. So it is possible that if "mechanical" is set to imperial units, the code for the plug-in does not know/does not understand how to interpret these units (converting between them, etc). This is just a hypothesis of what could be the issue though.

Hi great video Can this be tweaked so that the heat source remains static for a few seconds and the power of the laser increases either while moving or not moving? Thanks

@theengineeringguide8332

Hey! As for a static heat source this would be possible. In this case you would have to break this motion into 2 different heat sources. The first heat source would be have a velocity of zero over a certain period of time. Once that period of time is over, you would be able to specify a second heat source that starts in the location where the static heat source was and that has a velocity (and path) in order for it to move. As for varying power intensity, unfortunately this is one of the limitation using a plug-in rather than coding the APDL commands yourself. The plug-ins are much easier to use than the commands but you experience limitations using them. Unfortunately, unlike other forces and BCs, for the moving heat source, you are not able to specify the power intensity in terms of a function or a table (rather only 1 value can be specified).

@@theengineeringguide8332 Hi! Thanks for your previous answer. I have a couple last questions, would it be possible to change the heat distribution or shape of the laser beam like a normal distribution, cylindrical, square etc?? Also do you have any videos or resources you can share on ADPL commands or creating functions and tables? Thanks again !

Can you please provide a video on "How to apply Goldak heat source on the model of additive manufacturing? " On ANSYS software.
