mcdc.surface¶

mcdc.surface(type_, bc='interface', sensitivity=False, dsm_Np=1.0, **kw)¶

Create a surface card and return SurfaceHandle to define cell domain.

Parameters¶

type_{‘plane-x’, ‘plane-y’, ‘plane-z’, ‘plane’, ‘cylinder-x’, ‘cylinder-y’, ‘cylinder-z’, ‘sphere’, ‘quadric’}: Surface type.
bc{‘interface’, ‘vacuum’, ‘reflective’}: Surface boundary condition.
sensitivitybool, optional: Set to True to calculate sensitivities to the nuclide.
dsm_Npint: Average number of derivative particles produced at each sensitivity surface crossing.

x{float, array_like}: x-position [cm] for plane-x. If a vector is passed, positions of the surface at the times specified by the parameter t.
y{float, array_like}: y-position [cm] for plane-y. If a vector is passed, positions of the surface at the times specified by the parameter t.
z{float, array_like}: z-position [cm] for plane-z. If a vector is passed, positions of the surface at the times specified by the parameter t.
centerarray_like: Center point [cm] for cylinder-x (y,z), cylinder-y (x,z), cylinder-z (x,y), and sphere (x,y,z).
radiusfloat: Radius [cm] for cylinder-x, cylinder-y, cylinder-z, and sphere.
A, B, C, Dfloat: Coefficients [cm] for plane.
A, B, C, D, E, F, G, H, I, Jfloat: Coefficients [cm] for quadric.

SurfaceHandle: A surface handle used for assigning surface, and its sense, to a cell card.
