openmc.ZCone

class openmc.ZCone(x0=0.0, y0=0.0, z0=0.0, r2=1.0, *args, **kwargs)

A cone parallel to the x-axis of the form \((x - x_0)^2 + (y - y_0)^2 = r^2 (z - z_0)^2\).

Parameters:

• x0 (float, optional) – x-coordinate of the apex. Defaults to 0.
• y0 (float, optional) – y-coordinate of the apex. Defaults to 0.
• z0 (float, optional) – z-coordinate of the apex. Defaults to 0.
• r2 (float, optional) – Parameter related to the aperature. Defaults to 1.
• boundary_type ({'transmission, 'vacuum', 'reflective', 'white'}, optional) – Boundary condition that defines the behavior for particles hitting the surface. Defaults to transmissive boundary condition where particles freely pass through the surface.
• name (str, optional) – Name of the cone. If not specified, the name will be the empty string.
• surface_id (int, optional) – Unique identifier for the surface. If not specified, an identifier will automatically be assigned.

Variables:

• x0 (float) – x-coordinate of the apex
• y0 (float) – y-coordinate of the apex
• z0 (float) – z-coordinate of the apex
• r2 (float) – Parameter related to the aperature
• boundary_type ({'transmission, 'vacuum', 'reflective', 'white'}) – Boundary condition that defines the behavior for particles hitting the surface.
• coefficients (dict) – Dictionary of surface coefficients
• id (int) – Unique identifier for the surface
• name (str) – Name of the surface
• type (str) – Type of the surface

evaluate(point)

Evaluate the surface equation at a given point.

Parameters:point (3-tuple of float) – The Cartesian coordinates, \((x',y',z')\), at which the surface equation should be evaluated. Returns:\(Ax'^2 + By'^2 + Cz'^2 + Dx'y' + Ey'z' + Fx'z' + Gx' + Hy' + Jz' + K = 0\) Return type:float
