Cylinder mesh in Fortran
Hello everyone,
I am trying to create a simple cylinder mesh using Fortran (see the attached figure) and I think I did.
I want to make sure the cylindrical mesh I produced is correct and that is why I am here.
Please check and let me know if there are any changes.
Here is the code:
Code:
program cylinder_Grid
parameter (mmx=601,nmx=21,omx=601)
common/contr0/m,n,next,o
common/coord /x(mmx,nmx,omx),y(mmx,nmx,omx),z(mmx,nmx,omx)
m = 151; o = 11; n = 101
dxy = 1.d0; rad = 1.d0
dx = 3.d0/dble(m-1)
dy = 0.2d0/dble(o-1)
dz = 1.3d0/dble(n-1)
do k=1,n
do j=1,o
do i=1,m
ang = 0.4*(i-1)
x(i,j,k) = dx*dble(rad*cos(ang))
y(i,j,k) = dy*dble(rad*sin(ang))
z(i,j,k) = dz*dble(k-1)
enddo
enddo
enddo
print*,'z_end=',z(1,1,n)
open(2,file='cylinder.grd',status='unknown')
write(2,*) 'variables = x y z'
write(2,*) 'zone t="", i=',m,' j=',o,' k=',n
do k=1,n
do j=1,o
do i=1,m
write(2,*) x(i,j,k), y(i,j,k), z(i,j,k)
enddo
enddo
enddo
close(2)
stop
end program cylinder_Grid
