TITLE 'BC Sets'

 

COORDINATES cartesian2

 

VARIABLES u v

 

BOUNDARY CONDITIONS

'inlet' : value(u)=1   natural(v)=1

'outlet': natural(u)=1 value(v)=10

'side'  : natural(u)=0 natural(v)=0

 

EQUATIONS

 u: div(grad(u))=0

 v: div(grad(v))=0

 

BOUNDARIES

Region 1

  start(0,0) use bc 'side'

  line to (5,0) use bc 'outlet'

  line to (5,1) use bc 'side'

  line to (0,1) use bc 'inlet'

  line to close

 

PLOTS
