Materials and Media#
Section author: Norbert Grunwald
NB! Works for HEAT_CONDUCTION and TH2M (with Phase Transitions) only so far.
This example shows how to build OpenGeoSys media definitions directly
from a YAML-based Material Library using
MaterialManager
and MediaSet.
The YAML schema defines materials with:
name - unique material identifier
properties - sets of constitutive relations (with type, parameters, scope)
scope - indicates whether a property applies at phase or medium level
Together with the built-in process schemas (e.g. TH2M_PT),
these building blocks allow you to construct full Media definitions
including phases and components, and import them into an OGS project XML
via set_media().
from pathlib import Path
from tempfile import mkdtemp
import ogstools as ot
from ogstools import definitions as defs
model_dir = Path(mkdtemp())
Example materials#
Materials are provided as YAML files in the built-in Material Library. For example, here are the definitions of “opalinus_clay” (solid) and “water” (fluid):
print((Path(defs.MATERIALS_DIR) / "opalinus.yml").read_text(encoding="utf-8"))
print((Path(defs.MATERIALS_DIR) / "water.yml").read_text(encoding="utf-8"))

Media creation#
We build a MaterialManager from the built-in library, filter it with a schema, and construct a MediaSet object.
subdomain: the subdomain name (string, one per entry)material: must match thenamein the YAML filematerial_ids: list of integers corresponding to the MatIDs in the mesh (allows grouping several mesh regions under one subdomain name)
db = ot.MaterialManager()
subdomains = [
{
"subdomain": "host_rock",
"material": "opalinus_clay",
"material_ids": [0, 3, 4], # multiple MatIDs grouped under one name
},
{
"subdomain": "buffer",
"material": "bentonite",
"material_ids": [1, 2],
},
]
fluids = {
"AqueousLiquid": "water",
"Gas": "carbon_dioxide",
} # required by TH2M_PT schema
filtered = db.filter(process="TH2M_PT", subdomains=subdomains, fluids=fluids)
media = ot.MediaSet(filtered)
Export to OGS Project XML#
The MediaSet is imported into an OGS Project instance
via Project.set_media().
prj = ot.Project()
prj.set_media(media)
xml_file = model_dir / "material_test.prj"
prj.write_input(xml_file)
print(xml_file.read_text())
