CoEuler temporal scheme
Anyone had any luck using the CoEuler (local timestepping) temporal scheme?
I managed to figure out what parameters it needs in fvSchemes. i.e.
CoEuler (mass flux var) (density var) (max Courant number)
but I get the following error when I start the calculation:
Unsupported temporal differencing scheme : CoEuler
on patch outflow of field p in file "./airfoil/0.00992002/p"
From function advectiveFvPatchField<Type>::updateCoeffs()
in file fields/fvPatchFields/derived/advective/advectiveFvPatchField.C at line 265.
I took a look in the above source file but it looks like a major change would be necessary to get CoEuler to work.
I'm just using fixedValue derived type boundary conditions for the pressure. Is there some caveat about getting CoEuler thats not obvious?
you could try something like ... :
default CoEuler phi maxCo 0.5;
It has to do with the CoEuler not being support in the boundary conditions.
Anyone else have an ideas?
For others (as this question is old, but I was making a stupid mistake earlier ;) ), this is probably because p was set to
This doesn't make sense for a steady state simulation - as there are no propagation of waves when ddt = 0.
Instead, try setting to a fixedValue (equal to the static pressure value) at the outlet.
