Ram pressure stripping simulations - the co-evolution of interstellar and circumgalactic media

---

🏷️ Ram pressure stripping in clusters: Gravity can bind the ISM but not the CGM (https://arxiv.org/abs/2404.02035)

---

📂 ./hydro-rps/ is the codebase used to simulate our galaxy (with both CGM and ISM) facing constant ram pressure from intracluster medium using PLUTO (version 4.4 patch 2)

📂 ./control-setup1/ contains files used to simulate a control setup similar to the ram pressure stripping simulation by turning the gravity off. (the structure is similar to hydro-rps; major changes in init.c and definitions.h).

Check out my blog on the detailed steps to use Catalyst with PLUTO.

🏃 Initialization

• The procedure to set up our equilibrium condition is as follows:

• Compile Pluto with its dependencies and create the executable ./pluto

  make -j$(nproc) && make clean 
  

• Use the provided slurm jobscript to run parallelly on your supercomputer

  sbatch slurm-script
  

NOTE: Setting up the spack environment on clusters might be difficult sometime. Here's a quick documentation I prepared to use on our supercomputer Param Pravega.

🔖Important Files:

• init.c → problem initialization and on-the-fly analysis
• pluto.ini → input parameters
• definitions.h → problem / solver settings
• userdef_output.c → script for user-defined outputs
• *-pipeline.py → python files to be used during runtime by Catalyst
• generateCatalystAdaptor.py → generates the CatalystAdaptor.h file
