hi Every one!

i m using openfoam 201
i have problem to plot streamFunction i solved problem for laminar nonisothermal cavity flow with buoyantBoussinesqSimpleFoam.

when i run streamfunction then it gave me error but when i run another solver like icoFoam,SimpleFoam then streamfunction works but in buoyantBoussinesqSimpleFoam it cant work so what can i do?

plz tel me how can i plot streamFunction?

tel me how to plot streamFunction using buoyantBoussinesqSimpleFoam.
i found error like,

Create mesh, no clear-out for time = 0


Time: 0
--> FOAM Warning :
From function streamFunction
in file streamFunction.C at line 456
Flux field does not exist. Stream function not calculated

so anybody can solve my problem?

is there phi in your time folder?
you can use paraview or other post processing program to plot streams too

[jignesh_thaker2007]

yes in time folder phi is available.
so how can i write my data of stream function? because in other solver streamFunction command works but in this solver it cant work

i need the value of stream function so how can i run this command?

[nimasam]

is ur geometry 2D or 3D? streamFunction only works for 2D geometry

[jignesh_thaker2007]

ya in 2d. i short-out that problem but
when i give the command of streamFunction then it took the value of phi but it give me msg like

Reading field phi
Zero face: patch: 0 face: 0
..
Exhausted a seed. Looking for new seed (this is correct for multiply connected domains).



& when i plot this value in tecplot it gave me roungh answer
actually my value of vorticity is right but streamfunction value is incorrect so now tel me what can i do?

Did you managed to solve the problem?
