Dear all,

I’d like to have an L-shaped model with structured mesh, so I’ve installed UG, set Dune::UGGrid<2> as grid type and created a msh-file with gmesh (is there a simpler way?). I’ve set the runt-time parameter Grid.File (curiously only absolute path worked) and got this error:

Mandatory parameter 'Grid.Cells' was not specified. Abort!

This parameter should not be needed, when Grid.File is specified correctly, right? Does this mean that there is an error inside my msh-file?

Best regards!
Gergoe

PS: my msh-file’s structure is:

$MeshFormat
2.2 0 8
$EndMeshFormat
$Nodes
341
1 0 0 0
…
$EndNodes
$Elements
407
1 15 2 0 1 1
…
$EndElements
