Generate moment coefficientsΒΆ

The following steps are performed to obtain all the artifacts for force coefficient use case:

  1. Read parameters file

  2. Read Mesh description

    • Its path can be specified

    • Or it can be obtained from the simulation configuration file

  3. Read data for pressure coefficient

[1]:

from cfdmod.pressure.path_manager import CmPathManager
import pathlib

path_manager = CmPathManager(output_path=pathlib.Path("./output/pressure"))

Read parameters file

[ ]:

from cfdmod.pressure import CmCaseConfig

config_path = pathlib.Path("./fixtures/tests/pressure/Cm_params.yaml")
post_proc_cfg = CmCaseConfig.from_file(config_path)

post_proc_cfg

Read mesh from file

[3]:

from lnas import LnasFormat

mesh_path = pathlib.Path("./fixtures/tests/pressure/galpao/galpao.normalized.lnas")
mesh = LnasFormat.from_file(mesh_path)

mesh.geometry.vertices.shape, mesh.geometry.triangles.shape

[3]:

((1549, 3), (2915, 3))

Calculate moment coefficient

[ ]:

from cfdmod.pressure import run_cm

cp_path = pathlib.Path("./fixtures/tests/pressure/data/cp_t.normalized.h5")

run_cm(
    cp_h5=cp_path,
    mesh_path=mesh_path,
    cfg_path=config_path,
    output=path_manager.output_path,
)
