Do you want to automate insertion of the Moving heat flux objects in a tree?

As it is ullustrated in the video, I would like to create one moving heat flux that can travel around the rectangular object as many as I want (like a loop). To do so, I needed to create 60 heat flux, but it is not practical when I want to make 500 loops with keyboard. If you suggest to create automate the insertion of moving heat flux, that is also fine. Could you elaborate how to do?

or any other ways to use same heat flux that can make 500 loops around rectangular object?

Or any way to change the start and end time in an automated manner since it seems to does not have parameter sweep properties.

Ansys staff can not download any files on the forum, so if you want to reach a larger audience to get answers from, please insert inline images (like you have done) describing your problem. It would be possible to automate the Extension object insertion and property manipulation, but, an easier way would be writing a ds.dat file with limited number of moving heat transfer object and then simply extrapolating the same for large number of objects by simply editing the text file.

Thank you. Do you have any example on APDL input files written for moving heat flux extension? Any clue clould be great.

[Aniket Chavan]

No, but you can use your own model, and do the following:
Insert no moving heat transfer and write an input file from mechanical:
https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v212/en/wb_sim/ds_writing_reading_ansys_files.html
then insert for one loop and write out the input file.
Compare these two text files in text editors, this would give you an idea about what commands are being used, extrapolate for 500 loops. Let me know if you have further roadblocks!

Yeah, If I create my own model, then I can use every properties :). However, that is not the point of time saving. There is available ACT moving heat flux extension that saves time and is really useful but I could not use for shorter path like 2 mm when it moves in 5m/s so one needs to create more path or a loop structure or any sweeping properties but I do not have access any values of this extension that is the main drawback. Maybe you can improve it by including this feature that is really needed.

In the following APDL code, I m able to change the starting point of gaussian beam with ID number of coordinate system. However, I wanna change it in a loop so I included this do loop here but it only calls once. How can I make more loop so that beam can travel around the rectangle?

Can anyone help me in understanding the APDL codes? like what each and every number in the below command mean for Gaussian Heat source:

*SET,HEAT_FLX1(0,0,1), 0.0,-2,0,2,0,0,-1

Thanks
