Status| |Coverage Status|


Python 3.5 or 3.6 is required. Installing
`Anaconda <>`__ is recommended; it
works with Windows (64/32 bits), Linux (64/32 bits) and Mac (64 bits).

After installing Anaconda execute the following command at the command
prompt (cmd.exe for Windows, shell for Linux and Mac):


conda config --add channels conda-forge
conda config --add channels pedvide
conda install simetuc
(The first two commands add packages repositories with up-to-date versions of all needed packages.)



pip install simetuc

That will download and install all necessary files.

Note: Some OSX users report problems using conda, if after installing
you can't use the program (i.e., ``simetuc -h`` fails because simetuc
wasn't recognized as a command), use ``pip install simetuc``


If you installed it using conda, update with:


conda update -c pedvide simetuc

If you installed it with pip, update with:


pip install -U simetuc


- Command line interface program.

- Run with: ``simetuc config_file.txt [options]``
- See all options below and with: ``simetuc -h``

- The simulations are controlled by a configuration text file that the
user can edit with the parameters adequate to its system of study. It

- Information about the host lattice.
- Energy states labels.
- Absorption and excitation (including ESA).
- Decay (including branching ratios).
- Energy transfer.
- Other settings for the power and concentration dependence or

- simetuc works with any sensitizer and activator ion kind.

- The examples are given for the Yb-Tm system.

- All kinds of energy transfer processes are supported:

- Energy migration.
- Upconversion (ETU).
- Downconversion.
- Cross-relaxation.
- Cooperative processes.
- Energy transfer from sensitizers to activators.
- Back transfer from activators to sensitizers.

- See the example `configuration file <>`__ in
the simetuc folder.
- Add decay experimental data as two column text data, separated by
tabs or spaces.
- Different options:

- Create the lattice.
- Simulate the dynamics (rise and decay).
- Optimize the energy transfer parameters.

- Minimize the deviation between experiment and simulation.

- Simulate the steady state.
- Simulate the power dependence of each emission.
- Simulate the concentration dependence of the dynamics or the
steady state.

- All results are plotted and saved in the .hdf5 format.
- For all options ``--average`` uses standard average rate equations
instead of microscopic ones.


See the `manual <>`__.


- [ ] Add pressure dependence option: Change the distances of the
lattice and simulate dynamics or steady-state.
- [ ] Read experimental data in more formats.
- [x] Add cooperative sensitization (work in progress).
- [ ] Include pulse frequency for steady state simulations using a non
cw laser
