ogstools.meshlib.geo module

ogstools.meshlib.geo.depth(mesh, use_coords=False)

Returns the depth values of the mesh.

For 2D, the last axis of the plane wherein the mesh is lying is used as the vertical axis (i.e. y if the mesh is in the xy-plane, z if it is in the xz-plane), for 3D, the z-axes is used. If use_coords is True, returns the negative coordinate value of the vertical axis. Otherwise, the vertical distance to the top facing edges surfaces are returned.

Return type:

ndarray

ogstools.meshlib.geo.p_fluid(mesh)

Return the fluid pressure in the mesh.

If “depth” is given in the mesh’s point _data, it is used return a hypothetical water column defined as:

\[p_{fl} = 1000 \frac{kg}{m^3} 9.81 \frac{m}{s^2} h\]

where h is the depth below surface. Otherwise, If “pressure” is given in the mesh, return the “pressure” data of the mesh. If that is also not the case, the hypothetical water column from above is returned with the depth being calculated via ogstools.meshlib.geo.depth().

Return type:
