oxideRegrowth Python example error

[simbilod]

Run out-of-the-box, the oxideRegrowth Python example raises

simbil@simbilod ~/G/V/e/oxideRegrowth (update_examples) [127]> python oxideRegrowth.py config.txt    (process) 
Running 2D simulation.
Stability: 13.333333333333334
Traceback (most recent call last):
  File "/home/simbil/Github/ViennaPS/examples/oxideRegrowth/oxideRegrowth.py", line 50, in <module>
    domain.generateCellSet(
TypeError: generateCellSet(): incompatible function arguments. The following argument types are supported:
    1. (self: viennaps2d.viennaps2d.Domain, arg0: float, arg1: viennaps2d.viennaps2d.Material, arg2: bool) -> None

Invoked with: <viennaps2d.viennaps2d.Domain object at 0x7fe9aef75030>, 270.0, True

The faulty line is line 50 in the oxideRegrowth.py:

domain.generateCellSet(
    params["substrateHeight"] + params["numLayers"] * params["layerHeight"] + 10.0, True
)

The signature suggests that the second argument (material) is missing, see e.g. the C++ example:

  domain->generateCellSet(
      params.get("substrateHeight") +
          params.get("numLayers") * params.get("layerHeight") + 10.,
      ps::Material::GAS, true /* true means cell set above surface */);

However, rewriting line 50 as the following

domain.generateCellSet(
    params["substrateHeight"] + params["numLayers"] * params["layerHeight"] + 10.0, vps.Material.GAS, True
)

still raises an error:

The above exception was the direct cause of the following exception:

    cellSet = domain.getCellSet()

Unfortunately, the ViennaCS Python library, which provides the Cell-Set functionalities, is not yet available on PyPi. This package is required for the Cell-Set examples to work in Python.

However, we are actively working on a release for the ViennaCS Python package, so it should be available soon.
