Re: steady state in saturne to boundary condition in syrthes
i succeed in settnig the velocity profile but i can't set the temperature flow= 0, i added if (nscal.gt.0) then do ii = 1, nscal rcodcl(ifac,isca(ii),3) = 0 enddo endif but then i get : @ @ @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ @ @@ WARNING: ABORT BY BOUNDARY CONDITION CH...

Re: steady state in saturne to boundary condition in syrthes
so i could declare implicit double precision x, y, z
and then before the rcodcl(ifac,iu,1) = .....
set
x= cdgfbo(1,ifac)
z = ....
or i have to change directly in the equation?
and then before the rcodcl(ifac,iu,1) = .....
set
x= cdgfbo(1,ifac)
z = ....

Re: steady state in saturne to boundary condition in syrthes
ok ! i'll follow your suggest, but i have a problem on defining the velocity, in the GUI i used : r=0.306; xc=0.54; zc=0.76; alfa= (30/360)*(2*pi); dir_x = cos(alfa)*(abs(z-zc)/r)*((z-zc)/abs(z-zc)) + sin(alfa)*(abs(x-xc)/r)*((x-xc)/abs(x-xc)) ; dir_y = 0; dir_z = -cos(alfa)*(abs(x-xc)/r)*((x-xc)/ab...

Re: steady state in saturne to boundary condition in syrthes
i've tried something similar, decoupling the simulation and setting at the coupled surface of the stator a velocity inlet with a direction tangential to the cylinder, it works quite well but i'm forced to set a temperature to the inlet when i want to set the flux=0 option. Since it's a recycle fan i...

steady state in saturne to boundary condition in syrthes
Hi, in my experience of working with these softwares i modeled a metallurgical oven, where the workpieces load inside the oven are heated up both by convection (natural and forced by a rotating fan) and by surface to surface radiation (in syrthes). In a transient coupled simulation the timestep i sh...

Re: turbine modelling
Hi, you should create a small amount of fluid around your turbine (cylinder geometry is preferred) called 'rotor' inside your total fluid domain (stator), then you subtract the turbine's volume from rotor and set the icorio rotation for the rotor domain, the inner surfaces of rotor (that are the sur...

Automatic timestep in coupled cases
If i set both in saturne and syrthes the automatic timestep, how will the simulation go on? they both pick the minimum timestep (from saturne or syrthes) or they will go on in a indipendent (and so not correct) way?
thx
Andrea

Re: saturne 2.2 coupled with syrthes 3.4
solved the error ! i was so stupid that i sourced the syrthes.profile with a terminal opened in syrthes.profiles's location not in home/user... thx !
