[CIG-SHORT] how to turn off vtk output

[Brad Aagaard]

Tu,

As I mentioned yesterday, you need to set the vertex_data_fields and 
cell_data_fields to empty arrays to turn off output. As you can see in 
the info you posted, this VTK output is coming from the material.

Here are the steps to follow to figure out how to turn the VTK output off:

1. Load the pylith_parameters.json into the PyLith Parameter Viewer 
(follow the instructions in the manual to run it locally or use the 
online version at https://geodynamics.github.io/pylith_parameters/).

2. Search for VTK.

For each occurrence, look at the object one level above the data_writer 
to see what fields it is writing.

For example: The first occurrence is in 
[pylithapp.mesh_generator.distributor.data_writer]. Clicking on 
<pylith.topology.Distributor.Distributor> to the right of distributor, I 
see under "Details for Selected Component" that writer_partition is 
False, so no output will be written for this data writer.

Next, I see a DatWriterVTK for 
[pylithapp.problem.materials.crust.output.writer]. Clicking on 
<pylith.meshio.OutputMatElastic>, I see the cell_data_fields and 
cell_info_fields are not empty arrays.

Looking at the Details for Selected Component, the full path for the 
component is
[pylithapp.problem.materials.crust.output]. Notice that all of the 
properties and facilities have default values.

So to turn off output, within one of your .cfg files add:
[pylithapp.problem.materials.crust.output]
cell_data_fields = []
cell_info_fields = []

REPEAT for your man material.

Regards,
Brad
