The path to a clean OGS - pure python API

Example 1: BHE_mesh

from ogstools import examples
import ogstools as ogs

bhe_mesh = ogs.examples.bhe.mesh(params...)  # includes information about subdomains (boundaries)
bhe_prj = ogs.examples.bhe.prj()  # loads from OGS benchmarks (ogs6py-object)
# customize...
model = ogs.Model(bhe_mesh, bhe_prj, optional_execution_model (e.g. cores=5))
# alternatively:
model = ogs.examples.bhe.model()
results: MeshSeries, LogParser: log = model.run()

results.plot.contourf()
log.timesteps(.plot)

Example 2: feflow

from ogstools import examples
import ogstools as ogs

ms = ogs.MeshSeries.read_feflow_dac(feflow_file.dac) 


# Implementation of Model.read_feflow:
ogsmesh = ogs.OGSMesh(mesh, boundary_meshes) # .__init__(self) 


# Implementation of feflowModel
feflowModel = feflowModel(feflow_file)
boundary_meshes = feflowModel.get_boundaries() # dict['name_of_boundary_mesh']=boudnary_mesh: 
bulk_mesh = feflowModel.get_bulk_mesh() # pv.UnstructuredGrid
prj = feflowModel.get_prj() #ogs6py.OGS()
ogsmesh = ogs.OGSMesh(mesh, boundary_meshes) # .__init__(self) 
ogsmesh = ogs.OGSMesh.read_feflow(file.fem) # optional
ogsModel = ogs.Model(ogsmesh,prj)
ogsModel = ogs.Model.read_feflow(file.fem) #optional

# customize...
model.prj.parameters.density *= 2

results: MeshSeries, LogParser: log = model.run()

results.plot.contourf()
log.timesteps(.plot)

Example 3: custom gmsh mesh with existing benchmark prj as template

from ogstools import examples
import ogstools as ogs

mesh = ogs.Mesh.from_msh("path_to.msh")  # basically msh2vtu
prj = ogs.examples.THM.2D_consoliation.prj()  # loads from OGS benchmarks (ogs6py-object)
# customize...
model = ogs.Model(mesh, prj)  # map new meshes to prj??
...

Example 4: custom gmsh mesh with custom prj:

from ogstools import examples
import ogstools as ogs

mesh = ogs.Mesh.from_msh("path_to.msh")  # basically msh2vtu
prj = ogs.Project(input_file=ogs.examples.THM.2D_consoliation.prj())
# customize...
prj.add_timestep(...)  # ...
prj.save("filename.prj")  # optional
ex_conf = ogs.ExecutionConfig  # optional  (rethink naming)
# includes: 
#   path to binary, container
#   optiuonal parallelization
#   loglevel and all ogs binary args
model = ogs.Model(mesh, prj, ex_conf)  # map new meshes to prj??
model.run(
...
