pressure 2D list is converted to 1D when old inputstyle is autotranslated to the new one

[lnnbig]

Hi Sarath,

calphy version: 1.3.7
pylammpsmpi version: 0.2.13

Thank you very much for your support. I need the barostat to control pressure anisotropically, aiming for 50 GPa. Following your suggestion and the calphy documentation, I used the keyword: pressure: [[500000,500000,500000]]

However, I encountered an error, which is attached below. Full versions of these files are also included as attachments
file.tar.gz.

Seems like you have the old style input file. Calphy automatically translates it, but this is a bug that happens during this process. For the moment, you can use the new style input file. See below, could you please give it a try and see if that works?

calculations:
- element: [O, Si]
  equilibration_control: nose-hoover
  lattice: conf.data
  lattice_constant: 0.0
  mass: [15.999, 28.085]
  md:
    barostat_damping: 0.1
    thermostat_damping: 0.1
    timestep: 0.001
  mode: ts
  n_equilibration_steps: 1000
  n_iterations: 1
  n_switching_steps:
  - 1000
  - 1000
  pair_coeff: '* * SiOx_potential.yace O Si'
  pair_style: pace
  pressure: [[500000.0, 500000.0, 500000.0]
  queue:
    cores: 4
  reference_phase: solid
  spring_constants: [2, 4]
  temperature: [300.0, 1500.0]

Closing this as input file format is changed in the new version.
