1. icerise_docker_template.sif = Elmer SIF template file
2. runvalues.txt = each line in this file contains variable values in the order xa(characteristic accumulation length) a0(accumulation intercept) DivPos(Divide Position) filnam(filename)

4. runfunc.sh = runs the whole automated process. Steps:
   • References input file (runvalues.txt)
   • Reads variables from line of input file
   • executes update_sif.sif to create new SIF file for each line in input file
   • generates new folder icerise_run and moves all necessary files into proper structure
   • enters docker container with Elmer installed and executes ElmerGrid and ElmerSolver
   • dumps Surface.dat and Results.dat for each case into Google Bucket
