[FLASH-USERS] about setup a designed target configuration

[shuhua]

dear the flash developers

 i am a new learner of flash. i have learned how to run the laserslab example and it runs well.

now i want to change the target configuration（show in the figure）. the target is al and foams and the interface of al and foam is  sinusoidal modulation.

could you give me any advices on how to achieve it




Yours

Hua Shu

Hi Hua Shu,


I'd suggest reading the user guide (available here: https://flash.rochester.edu/site/flashcode/user_support/) which has a wealth of information.


To your question, you can modify your problem set up by navigating to the problem directory. For LaserSlab that's located:

${FLASH_DIR}/FLASH4.7/source/Simulation/SimulationMain/LaserSlab/



Then, modify Simulation_initBlock.F90 in your preferred text editor. In particular you probably want to modify these lines:



           if (sim_initGeom == "slab") then

              if(NDIM == 1) then

                 if ( xcent(i) <= sim_targetHeight + sim_vacuumHeight .and. &

                      xcent(i) >= sim_vacuumHeight ) then

                    species = TARG_SPEC

                 end if

              elseif(NDIM == 2 .or. NDIM == 3) then

                 if ( xcent(i) <= sim_targetRadius .and. &

                      ycent(j) <= sim_targetHeight + sim_vacuumHeight .and. &

                      ycent(j) >= sim_vacuumHeight ) then

                    species = TARG_SPEC

                 end if

              end if

           else

               if (sqrt(xcent(i)**2+ycent(j)**2+zcent(k)**2)<= sim_targetRadius) then

                  species = TARG_SPEC

              end if

           end if



I'm not quite sure what you mean by a ripple target. Maybe instead of a spherical/cylindrical selection just add some sines and cosines?


Best,
