This project includes all the research lines of the IFN plasma group. The Arwen, BigBarT and EMCLaw codes have been developed since the beginning of 2000 until now, including more than 9 doctoral theses involved in various developments of these codes. In this project, a continuation of several previous ones, we propose to improve and extend the physical models included in the codes, to improve some numerical methods and to improve the EOS and opacity data. There are 4 doctoral theses being developed in this project.

Experiments conducted in EuXFEL interepretated with BigBarT (see PRE 2025 article). Shake off processes clearly responsible for the peaks in Ka Kb satellites as seen in the above image.

1.  Multi-group radiation diffusion solver for AMR with matrix free in progress. 

2. Multimaterial 3D, testing the new formulation.

3. 3D graphics using external libraries and openspurce CAD programs.

4.  New EOS fitted to experimental and DFT+PIMC results.

5. New opacity data for low and high Z materials obtained with BigBarT

6. Only the 1D solver has been modified. Now BigBarT includes angular and 1D dependence. New version is 3 to 10 times faster. 

7. MC solver: We had chosen the MC solver, but at the same time we have found another formulation that can be much more effective. We are evaluating both.

8.  Acceleration of BigBarT for high Z: The code now simulates high Z, Au for example, in less than 24 h

9. The different 3D PIC codes available in open source (WARPX, SMILEI and EPOCH) were evaluated. EPOCH was chosen for EMcLAW, but a bug in the EMcLAW CCs prevented progress, now solved and we are running all the planned cases. 

10. Dispersion with Padè tables has been included. Work on HHG propagation analysis in dense plasmas is being completed. The new scheme still need stabilization.

11. Our Maxwell-Bloch model has been enhanced, now being capable of treating structured light, as Laguerre-Gauss beams carrying different topological charge.
