Onelab/Mobile is available for iOS (iPhone and iPad) and Android:

Onelab/Mobile contains Gmsh and GetDP and runs all computations locally on your mobile device.

Running a pre-packaged model

The list of available models appears when you launch the app. Selecting a model will load it. You can then press Run to launch a simulation with the default set of parameters. When available, additional information about a model can be obtained by long-pressing on the model description and selecting Visit model website.

Modifying a model

To run a model with different parameters, press Parameters and modify any of the presets. Then press Run again: all the simulation steps will be performed with the new parameter values. To restore the preset parameters values, press Reset.

Advanced users can also directly edit the model input files: long-press on the model description and select Edit model files. To free up space, temporary model files (meshes, solution files) can be removed by long-pressing on the model description and selecting Clear results. To completey remove a model, long-press on the model description and select Remove.

Sharing a model

To share a model by email, long-press on the model description and select Email model files.

Installing a new model

To install a new model:

  1. Put all the model files (.pro, .geo) in a directory, which should also contain a file named infos.xml with the model information:
    <?xml version="1.0" encoding="utf-8"?>
    <models>
      <model>
        <title>Your model title</title>
        <summary>Your model summary</summary>
        <file type="pro">your_main_pro_file.pro</file>
        <preview type="png">your_128x128_pixel_screenshot.png</preview>
        <url>http://your_model_website.com</url>
      </model>
    </models>
    

    (See e.g. Inductor or Waveguides.)

  2. Zip the directory.
  3. Open the .zip file on your device (e.g. through iCloud, Dropbox or Google Drive; or by emailing it to yourself and opening the attachment; or by putting it on a web server and downloading the file on the device with Safari or Chrome).

The new models will be extracted alongside the app's built-in models.
