Hello, I am trying to simulate Laser shock peening process via Ansys but I am not so professional on it.

I learned from articles how the pressure acts over the laser spot area and formulation of the pressure which changes respect to time and spatial coordinates as below;

Hi mozer, a few weeks ago I did a simulation in which I applied a pressure varying in space and time. The idea behind this simulation is that you need to create a single file per each time instant, and in each file you write the coordinates of each finite element on which to apply the pressure load, and the associated pressure at that time instant. For this reason it's helpful to have a regular mesh, so that you don't struggle defining the coordinates. To create the files I used Microsoft Excel and exported them as .csv files, in this way they could be read by Ansys.
Here is the video tutorial I learned it from: https://www.youtube.com/watch?v=Xj0s9XC_uhU
It's not exactly the same since in the video it sets a temperature instead of a pressure but I assure you it works even with pressure. Pay attention to the advice it gives at the end of the video, it says that, when having many data, it's useful to set a single file (e.g. the first one) as the master so that the coordinates are read from there for all the files. This helps saving time, I inserted 3600 files and it was very helpful!
There is also a pdf in which this is explained in case the video is not clear: https://www.padtinc.com/blog/wp-content/uploads/sites/2/2017/03/PADT-ANSYS-Tabular-Loading-ANSYS-18.pdf
Have a good day,
