MaterialGrid in MPB? #2603
-
|
Hi everyone, I'm wondering if MEEP's MaterialGrid class is supported in MPB. I've attempted to use it (by assigning it to default_material), but I get error: "meep: unknown material type". I've attached my a screenshot of my script. I have verified that the data I'm importing is in the form of a 16x16x16 np.array. If MaterialGrid is not supported in MPB, can anyone recommend a way to make custom geometries in MPB when those geometries are not easily defined by a function? Preferably if there is a way to create a custom geometry from a numpy.array of weights (like with MaterialGrid) or similar. Thanks to any and all for your help! M |

There is internal support for material grids in MPB (in fact, much earlier than Meep!), but no Python interface as yet. You could use the |

Fantastic. Thank you! epsilon_file is exactly the kind of thing I'm looking for. |

You could use the
epsilon_filefeature to read in data off a grid from an HDF5 file.
