Combines and converts a
.mesh file and a
.param file into a corresponding
mesh2vtu.py input.mesh input.param output.vtu
Combines multiple parameter files (
.param) into one. All the files are validated to ensure each parameter has the same number of elements.
meshmerge.py [-h] [-o outfile] infile [infile ...]
Path to the n input parameter files to merge into one
Optional path to the output parameter file. If not given, defaults to a filename of concatenated input files.
Because of how the triangles are generated and subsequently written to file, triangles that are close in space may not be close in the file. Therefore, if the mesh is used in a numerical model, it may result in inefficient access. This tool computes the permutation of a mesh that minimizes the bandwidth of the connectivity matrix.
This tool adds a new field
cell_global_id to the
.mesh file. A consuming program can sort the triangles (i.e.,
mesh.elem see: .mesh) by these ids. Then, spatially close triangles will also be close in memory. This may be visualized by plotting the nearest neighbour connectivity before and after reodering.
mesherpermuation.py [-h] [-o outfile] [-t type] [-i infile]
File for output. Overwrite input file
rcm Performing RCM bandwidth minimization (default)
nd Performing ND fill-in minimization
Produces a csv file of detailed per-triangle information: the error (‘rmse’ is computed), triangle area (units^2), min and max inner angles (degrees).
These values are also written to the
_USM.shp file in the mesher output directory.
Expects that the
.mesh is in a projected CRS.
Note that the triangles’ RMSE is recomputed, so can be a bit slow on very large meshes.
write_shp=True as the shp file is used to load triangle geometry.
Directory to output directory produced by mesher.
