Bases:
PointVTKInferencerInferencer for creating volex representations. This inferencer works bu creating a uniform mesh of voxels and masking out the ones defined by a callable function. The result is a voxel based representation of any complex geometery at any resolution.
- Parameters
bounds (List[List[int]]) – List of domain bounds to form uniform rectangular domain
npoints (List[int]) – Resolution of voxels in each domain
nodes (List[Node]) – List of Modulus Nodes to unroll graph with.
output_names (List[str]) – List of desired outputs.
export_map (Dict[str, List[str]], optional) – Export map dictionary with keys that are VTK variables names and values that are lists of output variables. Will use 1:1 mapping if none is provided, by default None
invar (Dict[str, np.array], optional) – Dictionary of additional numpy arrays as input, by default {}
mask_fn (Union[Callable, None], optional) – Masking function to remove points from inferencing, by default None
mask_value (float, optional) – Value to assign masked points, by default Nan
plotter (Plotter, optional) – Modulus Plotter for showing results in tensorboard., by default None
requires_grad (bool, optional) – If automatic differentiation is needed for computing results., by default True
log_iter (bool, optional) – Save results to different file each call, by default False
