I've tried the following...

Under the body forces (BF3 refers to the basal boundary):

- Code: Select all
`Body Force 3`

Zb Accumulation = Real 0.0e0

BDrag = Variable Coordinate 2

Real Procedure "ElmerIceUSF" "SlidCoef_Contact"

End

Then, a new solver:

- Code: Select all
`Solver 11`

Exec Solver = Always

Equation = Result Output

Procedure = "ResultOutputSolve" "ResultOutputSolver"

Vtu Format = Logical True

! Exported Variable 1 = BDrag

Vector Field 1 = String BDrag

! Scalar Field 1 = String Ne

End

I get the following when I run it:

- Code: Select all
`WARNING:: WriteVtuXMLFile: Nonexistent variable: bdrag`

WARNING:: WriteVtuFile: Are there really no scalars or vectors?

Plus a set of vtus/case0001.pvtu which contains the mesh but no variable values. Is someone able to explain what I'm doing wrong?

Thanks

Matt
