![]() ![]() While not memory efficient, this function will ubiquitously work with all data as long as spatial coordinates are provided. The number of data points in the first dimension of all arrays in the input dictionary must be consistent.Īdditionally, the dictionary must include variables that represent the items’ spatial location. VTK stands for Visualization Toolkit, whichtogether with ParaView, a standalone 2D/3D visualization applicationrepresents an open-source multi-platform project backed by Kitware, Inc. ![]() This function converts the dictionary, Dict, of variable data into a point cloud using a vtkPolyData dataset. vti filename extension has its primary association with the ParaView/VTK XML Image Data (VTI) file type and format. When writing a custom constraint, inferencer or validator, using one of these functions will likely be needed to record your results. The workhorses of Modulus’ post-processing are the two functions var_to_polyvtk and grid_to_vtk, which are used for unstructured point data and grid data, respectively.īoth of these functions take dictionaries of numpy arrays and write them to VTK files. Modulus currently does not support multi-block VTK files. Modulus primarily will use vtkPolyData to output data given its flexibility, but other formats can offer significant memory savings if applicable. Generally speaking, these file types are listed most to least restrictive. Can contain objects including points, lines, faces, cells, etc. This includes structured meshes with curved boundaries.ĭata stored on an unstructured mesh domain. Modulus supports several VTK data formats (legacy and XML versions) including:ĭata stored on a uniform grid, such as an image.ĭata stored on a rectilinear domain, such as a square domain with nonuniform mesh density.ĭata stored on a structured domain. VTK outputs are selected by default in Modulus, which can be controlled using the save_filetypes parameter in the Hydra config. Modulus supports several VTK utilities to help make importing and exporting data effortless. If you are unfamiliar with VTK and ParaView, you are encouraged to look over the ParaView documentation to help get started. The primary output file format supported by Modulus are Visualization Toolkit (VTK) files which are widely used across multiple scientific domains.Ī key benefit of VTK files is VTK’s large library of filters one can use on the data as well as support from industry standard visualization software support such as ParaView. linspace ( extent, extent, 100 ), indexing="ij", ) # linearly interpolate points onto mesh us = return us # define mesh to interpolate onto xyi = np.
