Accessing data from UAL requires some modification to your code. In this part of tutorial, we will take a closer look on how to access CPO via UAL.

3.1 Accessing data using Python
...
What you can see here is a simple code that stores particular CPO into MDSPlus database using UAL.
| Code Block |
|---|
import sys
from pylab import *
import ual
cpo = ual.itm(12,2)
cpo.create()
if not cpo.isConnected():
print 'error during itmdb entry creation'
sys.exit(1)
cpo.equilibriumArray.resize(1)
equi = cpo.equilibriumArray
equi.array[0].time = 0.0
equi.array[0].datainfo.dataprovider = 'MKO'
equi.array[0].datainfo.putdate = '18/02/2013'
equi.array[0].codeparam.parameters = 'param'
equi.array[0].eqgeometry.boundary.resize(1)
equi.array[0].eqgeometry.boundary[0].r = sin(arange(0,2*pi,2*pi/100))
equi.array[0].eqgeometry.boundary[0].z = cos(arange(0,2*pi,2*pi/100))
print equi.array[0].eqgeometry.boundary[0].r
print equi.array[0].eqgeometry.boundary[0].z
equi.put()
cpo.close() |
Let's check how to read these data in Fortran.

4. You should see code similar to following one
| Code Block |
|---|
program diagnostic
use euitm_schemas
use euitm_routines
use write_structures
implicit none
integer :: idx
type (type_equilibrium), pointer :: equilibrium(:)
Integer x
call euitm_open('euitm', 12, 2, idx)
call euitm_get(idx, 'equilibrium', equilibrium)
write (*,*) "Size of CPO: ", size(equilibrium)
write (*,*) "Value of r: ", equilibrium(1)%eqgeometry%boundary(1)%r(1)
write (*,*) "Value of z: ", equilibrium(1)%eqgeometry%boundary(1)%z(1)
call euitm_close(idx)
call euitm_disconnect()
end program |
...
5. Run the code
| Code Block |
|---|
make clean
make
./readEquilibrium |
6. You should see values that we have stored using Python based code.
