Generate Random Particles for Accurate Integration

Generate Random Particles and Accurate Integration MPM Scheme

Design Detail

• Have a new particle generator (currently either from 'fileor atgauss points`)
• This generates random particles within a cell, on which the weights will be computed separately to ensure accurate integration
• The weights will ensure accurate integration

Implementation Detail

• Start with generate random particles first
• Then once that's done, we will compute the gauss weights

After discussion with @kks32, we will change this from cell (generate points function).

The new input JSON file might look something like this with label random:

  "particles": [
    {
      "generator": {
        "check_duplicates": true,
        "cset_id": -1,
        "particle_type": "P2D",
        "material_id": 2,
        "pset_id": 2,
        "particles_per_cell": 20,
        "type": "random"
      }
  ]

Could we have separate issues for updating weights and random particle generations?

Understood, will start with random particle generations first
