List of quantities we can write to text output.
Unlike QuantityId, this includes derivatives of quantities (for example velocities) and 'virtual' quantities like smoothing lengths. It can be also stored as flags.
| Enumerator | |
|---|---|
| POSITION | Positions of particles, always a vector quantity. |
| VELOCITY | Current velocities of particles, always a vector quantity. |
| SMOOTHING_LENGTH | Smoothing lenghts of particles. |
| MASS | Particle masses, always a scalar quantity. |
| PRESSURE | Pressure, reduced by yielding and fracture model (multiplied by 1-damage); always a scalar quantity. |
| DENSITY | Density, always a scalar quantity. |
| ENERGY | Specific internal energy, always a scalar quantity. |
| DEVIATORIC_STRESS | Deviatoric stress tensor, always a traceless tensor stored in components xx, yy, xy, xz, yz. |
| DAMAGE | Damage, reducing the pressure and deviatoric stress. |
| ANGULAR_FREQUENCY | Angular frequency of particles, used in N-body simulations. |
| STRAIN_RATE_CORRECTION_TENSOR | Symmetric tensor correcting kernel gradient for linear consistency. |
| MATERIAL_ID | ID of material, indexed from 0 to (#bodies - 1). |
| INDEX | Index of particle. |
|
strong |
Type of simulation, stored as metadata in the binary file.
This value is used when reading the data in ssf player (to select proper visualization) and when resuming a simulation (to continue in correct phase). When a new type of simulation is added, either modify this enum or create and additional enum (with no conflicts with this one) and cast it.
