Instructions to define additional solution quantities of AcuTrace called user equations.
- Input File
  To access a user-defined function in AcuTrace, you must reference it in the input file.
- Function Format
  An AcuTrace user-defined function has the following form (in C).
- Compile, Link and Run
  In order for AcuTrace to access the user-defined functions, the functions must be compiled and linked into a shared library. The script acuMakeLib may be used for this purpose.
- UFP-Support Routines
  Within an AcuTrace user-defined function, data may be accessed through support routines. These routines provide flexibility, longevity, efficiency and the ability to check for run-time errors.
- Basic Routines
  These routines are accessible by all AcuTrace user-defined functions.
- Particle Routines
  These routines are accessible by all AcuTrace user-defined functions. The routines access the particle data at the current particle location and time.
  - ufpGetTime()
    Get the particle time.
  - ufpGetTimeInc()
    Get the time increment for the current particle segment.
  - ufpGetParticleData()
    Get the array of particle data.
  - ufpGetJac()
    Get the pointer to the source Jacobian.
  - ufpGetUdfData()
    Get the pointer to the user equation solution.
  - ufpGetNumUdfData()
    Get the number of values in the user equation solution.
- Flow Routines
  These routines are accessible by all AcuTrace user-defined functions. The routines access the flow data at the current particle location and time.
