## Two-Dimensional Simulations

### Creating Solid Block

`# Generating points using .awk fileawk -f nicholson.awk > points.tmp# Delaunay triangulation and transformation using gts tools( wc points.tmp | awk '{print \$1" 0 0"}'; cat points.tmp ) | gtsdelaunay -d | gtstransform  --rx=-90 > nichol_test.gts# Shifting points to the domain boundarysed -e "s/ -0.0168/0/g" < nichol_test.gts > nichol_testout.gts`

The .awk file used to generate the points is

`BEGIN {          a=0.272          b=1.7          alpha=atan2(a,b);          h=a*cos(alpha);          l1=b*cos(alpha);          l2=a*sin(alpha);           for (k=0; k <= 100; k++) {            for (i=-1; i <= 100; i++) { printf("%5.4f %5.4f %5.4f\n",l1*i/100, -0.85+1.7*k/100 , h*i/100) }            for (i=1; i <= 101; i++) { printf("%5.4f %5.4f %5.4f\n",l1+l2*i/100, -0.85+1.7*k/100, h*(1-i/100)) }          }            dx=1.0e-4          k=0.          j=-1.          for (i=-1; i <= 100; i++) { printf("%5.4f %5.4f %5.4f\n",l1*i/100, -0.85+1.7*k/100-dx,h*j/100) }          for (i=1; i <= 101; i++) { printf("%5.4f %5.4f %5.4f\n",l1+l2*i/100, -0.85+1.7*k/100-dx,h*j/100) }           k=100.          for (i=-1; i <= 100; i++) { printf("%5.4f %5.4f %5.4f\n",l1*i/100, -0.85+1.7*k/100+dx,h*j/100) }          for (i=1; i <= 101; i++) { printf("%5.4f %5.4f %5.4f\n",l1+l2*i/100, -0.85+1.7*k/100+dx,h*j/100) }}`
