Vignesh Sitaraman bb05baf89d modified: Armory/ClassPW.h changes made to explain the andoe and cathode shifts in a more intuitive geometric manner 
modified:   MakeVertex.C changed code to make nA plots instead of nA0C to add more stats to n anode analysis
	modified:   anasen_fem/paraview_plotter.py changed the analysis to plot every 32nd field line, dure to indreaed field density from the new wire shift
	modified:   anasen_fem/run.py going from 0 to 174.6 in 17.43 increments to account for the remeasured lenth of the pc
	modified:   anasen_fem/scalars.dat.names
	modified:   anasen_fem/wires_gmsh2d_bc.py length of pc changed, 4 wire shift incorporated, set mesh order to 2 to decrease the meashing density
    pccal folder seems to make 17F analysis work, not sure why still trying to figure it out

README.md

README for ANASEN fem simulations:

  • There are a few iterations of these simulations that already exist. Be sure to also locate and refer to them if necessary.
  • Install gmsh and its python api by running (Ubuntu 22.04 LTS)
		sudo apt install gmsh python3-gmsh

  • Gmsh gives us the tools to create a meshgrid that samples the 2d space appropriately to plot the field/equipotential lines.

  • The output file typically has the .msh extension. This is read as input to Elmer, which is the FEM differential-equation solver.

  • Install Elmer via the following steps:

		sudo add-apt-repository ppa:elmer-csc-ubuntu/elmer-csc-ppa
		sudo apt install elmerfem-csc-eg
  • Install ParaView for visualizations by downloading from the Linux .tar.gz link at https://www.paraview.org/download/
    • The current version is tested to work on Paraview 6.1.0. The default version in Ubuntu 22.04 repositories has some trouble with scripting
  • v0.0.1, March 10 2026
    • 2d simulations of fields only. gmsh for meshing, elmer for fem, paraview to plot
    • Before running, open paraview_plotter.py to make the bash shebang (#!) point to the location of pvpython or pvbatch
    • python3 run.py should run everything in order, and is hopefully all the files are self-documenting
  • v0.0.2, planned TODO
    • Garfield to take Elmer results and perform charge-transport
