How autodyn imports external energy deposition

      Hello, I have a question about autodyn. I would like to ask you how autodyn imports external energy deposition. I built a copper cylinder, and then knew the energy deposition corresponding to each point in it. How can I introduce the energy deposition into the cylinder, and then calculate the density pressure after a certain time, etc. I tried to carry out secondary development of autodyn and found that the EXSIE module in the subroutine can import energy deposition, but it only has one input parameter. I don't know how to input it, so I would like to ask for advice.

      The picture shows the subroutine EXSIE

      The picture shows the energy deposition I want to import. The first and second columns are the coordinates, and the third column is the corresponding energy deposition.

      Hi

      I would suggest to post this in the explicit dynamics forum.

      /forum/forums/forum/discuss-simulation/ls-dyna/

      All the best
