Laura Gonzalez matflow help

Some scoping meeting notes: 2 problems

1. grain orientations in matflow not as expected, even before processing - perhaps data preparation isn't in the correct format for matflow? euler angles vs quaternions. matflow/damask reads in quaternions There are different sequences of xyz/zxz rotations possible IPF colours Laura to look at different methods of converting between euler angles and quaternions to see if she can get back the correct answer - can we work out what format Damask is expecting? Does damask document how to convert between euler angles and quaternions?

2. want to reduce resolution of analysis of rve matflow error when reducing resolution, but not always.

Laura will send a Matflow workflow to try.

Laura sent a workflow that I've not looked at yet.

Regarding 2: I'm looking at running this on CSF3 (and/or locally) but the workflow file is in an old format. Laura is using

matflow, version 0.2.26
~/.local/bin/matflow

i.e. an old installation in her user space.

I'm going to see what progress I can make using a newer version of matflow.

@lauragondu has partially solved 1. but only for artificial microstructures, rather than her experimental microstructures

I'm looking through the matflow code and have found a couple of leads, which I'll have a look at this week

• the demo-workflow damask_input_files
• workflows/RVE_extrusion_EBSD_DIC.yaml contains schema: modify_VE_add_buffer_zones, which is in template_components/task_schemas.yaml as - objective: modify_VE method: add_buffer_zones

Laura has more or less fixed 1, and 2 is now captured in https://github.com/LightForm-group/laura_ve_loading/issues/1
