Dear Neks

   I have created (and succesfully used) a
2d axisymmetric mesh (see attachment) for
two coaxial jets discharging into "free air".
What I want to do now is to revolve it
around the z (x) axis to create a 3d one
and simulate the non-axisymmetric flow .

I tried using n2to3 without success with the
following input parameters:

coaxJets               old name
coaxJets3              new name
1                      For ASCII output only: 0; For .rea/.re2: 1
-10                    input number of levels: (1, 2, 3,...; < 0 for
circular sweep.):
0                      input z min:
360                    input z max:
1                      input gain (0=custom,1=uniform,other=geometric
spacing):
no                     This is for CEM: yes or no:
P                      Enter Z (5) boundary condition (P,v,O):

but I get the following error:
 this is cbz: P  P   <--- 
  ERROR READING CURVE SIDE DATA
  ABORTING IN ROUTINE RDCURVE.

I have also tried reducing the mesh to the first
block only, i.e., the inner tube, but I get the
same error.

What am I mistaking?
