Module containing the FluidMeshInfo class.

FluidMeshInfo

class ansys.dpf.post.mesh_info.FluidMeshInfo(core_mesh_info: MeshInfo)

Holds the metadata relative to a fluid mesh.

This class describes the available mesh information. Use this to gather information about a large mesh prior to loading it to define requests on limited parts of the mesh for improved performance.

Parameters:

core_mesh_info (MeshInfo) – Hold the information of the mesh region into a generic data container.

Examples

Explore the mesh info from the model

>>> from ansys.dpf import post
>>> from ansys.dpf.post import examples
>>> files = examples.download_fluent_axial_comp()
>>> simulation = post.FluidSimulation(cas=files['cas'][0], dat=files['dat'][0])
>>> mesh_info = simulation.mesh_info
>>> print(mesh_info)
