Description

This command is used to define Finite Element (FE), Discrete Particle (DP), Computational Fluid Dynamics (CFD) or Rebar (RB) sensors. Stresses, coordinates, displacements and velocities are output in the local coordinate system (if defined). Also the sensor location $(x_0, y_0, z_0)$ is defined in this local coordinate system.

Part ID (FE)

An FE sensor samples the local state at a material point initially located at coordinate $(x_0,y_0,z_0)$. The solver uses the nearest integration point and node (in the specified part) and outputs the sampled data to the ASCII file sensor.out.

Discrete particle (DP)

A DP sensor must be assigned a radius $R \gt 0$. The local density, velocity and pressure are estimated in an averaging process that requires many particles (preferrably more than 100). Data is written to the ASCII file particle_sensor.out.

Computational Fluid Dynamics (CFD)

CFD sensor signals are output to the ASCII file cfd_sensor.out. The radius $R$ is optional and it is only used if the CFD cell at $(x_0,y_0,z_0)$ is blocked by an overlapping Finite Element or SPH particle. The solver will then seach for, and pick up the signal from, the nearest unblocked (active) CFD cell.

Rebar (RB)

Rebar sensor data is written to rebar_sensor.out.
