Installing new models on iOS

In order to install a new model on iOS, you need to bundle it inside a directory with extension .bundle. The directory should contain a file named infos.xml containing the model information (see e.g. the Inductor example). You can then use file sharing in iTunes to install the model on your device.

Installing new models on Android

On Android, you can simply open .geo or .pro files from a file explorer.

Compiling Onelab/Mobile

iOS

You need a Mac with Xcode >= 4 and the iOS SDK >= 7.0 to compile the Onelab/Mobile application. The app depends on several external frameworks (Gmsh, GetDP, PETSc, BLAS, LAPACK) ; scripts in the Gmsh SVN repository show the steps required to build these frameworks and the app for the simulator and the actual device (login=gmsh, passwd=gmsh).

Android

You need the Android SDK with level >= 14, as well as the Android NDK to compile the libraries that Onelab/Mobile depends on. The app depends on several external frameworks (Gmsh, GetDP, PETSc, BLAS, LAPACK) ; a script in the Gmsh SVN repository shows the steps required to build these frameworks and the app (login=gmsh, passwd=gmsh).
