+Jan's HiDEM model.
+
+##### Compilation ####
+
+Compilation requires the cray ftn compiler:
+
+module swap PrgEnv-gnu PrgEnv-cray
+
+#### Getting data ready ####
+
+Replace no data with zero
+
+scale friction down 
+
+adjust the waterline
+
+Choose the number of cores
+
+do something to the restitution coefficient
+
+#### simulation blow up ####
+
+if the simulation explodes (particles moving too far):
+
+Change DMP and DMP2 - multiply by two.
+
+#### Files etc ####
+
+These are part of the compiled code:
+
+wave2.f90
+dist.f
+circ.f
+effload.f
+amat.f
+tmat.f
+ttmat.f
+kmat.f
+glas.f90
+ranmar.f
+dt.f90
+
+ave*.f - these compute averages of something
+
+*.job - job scripts for torque
+
+comp.txt - the compilation command
+
+rc2.f90 - compute the calved size distrib
+
+### input files ###
+
+inp.dat
+mass3.dat
+param.dat - don't worry - something about opening files
+
+### mass3.dat ####
+
+mass3.dat is the input configuration, in format:
+
+x, y, surface, base, bed. friction (Newton seconds per metre) 
+
+x and y must start at zero, must have a (0,0) corner.
+
+output transformation matrix which takes from Elmer domain to HiDEM domain.
+
+make sure the bed is buffered beyond the edge of the ice, and define these regions by setting surf and base equal to bed.
+
+
+"YN" is the number of partitions in the Y direction.
+"NTOT" is the total number of partitions in the model
+GRID - The grid size of the mass3.dat data, make sure it matches
+SCL - diameter of each particle
+RESTART - 1 = true
+
+
+
+#### OUTPUT - jyr files and STR files ####
+
+List position of all particles in x,y,z, every 2 seconds.
+Read this in paraview quite easily.
+
+STR file:
+
+midpoint
+strain
+
+for each node connection in initial geometry (including broken bonds)
+
+
+dtop* files - these show the total energy in the system for different parts
+
+Time
+WENS - elastic energy of the spheres - imagine the particles overlap and are deformed against each other. Then they might bounce back apart.
+ENMS+ENMS0 - elastic deformation energy - the energy held in a deformed/bent system
+MGHS-MGH0 - potential energy
+Kins - kinetic energy
+
+#### Processing ####
+
+rc2.f90 computes the size distribution of calved blocks
+
+size  count
+
+1  452000
+2  4560
+3  985
+...
+largest_block 1
+
+'maxi' is the same as jyr but for the largest intact block (e.g. the remaining glacier)
+
+rh2.f90 - computes velocity
+rh.f - computes strain
+
+
+INFI1 - first JYR
+INFI2 - second JYR
+N - wc -l JYR0001.csv
+max - 10?
+
+#### PARAVIEW ####
+
+First simply load csv, with blank space delimiter, merge delimiters, has no header
+Then apply table to points filter
+Then ensure enable ospray and shadows, and pick point size that makes them touch
+
+For the sea: add a box, set size and centrepoints
+
+For the bed: get bed.csv, read it in same as other CSVs
+then apply Delaunay2D filter.
