Lithosphere removal (delamination) following continental collision: shape and complexity of observables predicted from 3D numerical models

Upload contains most essential data files from the manuscript. The raw data amount to several TB and cannot be uploaded.

1    Model data

1.1 Models covered

Relatively frequent output is available for the reference model (R in paper, see Table S2), prefixed dp10. Limited output is uploaded for models with geometric variations (OSM -> dp19, TSM->dp26).

1.2 Types of data

Most files are visualisation files (ending *.vtr). These are intended for loading into the visualisation software Paraview. Files starting with comp_ contain the lithological composition field; other visualisation files hold the fields of selected physical parameters. Note that as of the design of the study, the maximum file size allowed for loading into Paraview is ca. 2 GB. This limits the number of fields available according to model size - larger models (geometrical variations) hold therefore less fields.

Binary files with ending *.prn are saved model states, from which programs can be rerun.

Time information mapping step numbers to years is provided in times...txt.

2   Software for reproduction

The numerical code is not in the public domain, and its use is restricted. A pre-compiled binary is provided and allows reproduction of the main/reference model. We present the input files; however, these cannot be changed freely (equivalent to software distribution), and changes will lead to termination of the program.

2.1  Requirements, preparation and use

The code is compiled on CentOS with gcc 4.8.2. There is no library dependency, apart from the intrinsic OpenMP and glibc (>= 2.17). The following requirements must be satisfied in order to run it:

• Linux OS (tested on CentOS and Fedora)
• > 160 GB shared memory

The following provisions are recommended:

• 16 cores
• high bandwidth storage
• storage space O(TB)

To prepare, simply unzip the provided snapshot clsd_reproduce_gcc_CentOS.zip in an appropriate directory (cluster). The input file init.t3c sets the initial conditions; the input file mode.t3c controls solver and file output. file.t3c is the pointer to the last output step; if a model snapshot is available as binary dump (*.prn file), setting the pointer to its number allows restarting.

For normal usage, create initial condition with executable in3mg, and subsequently run i3mg. This will create snapshots and *.vtr visualisation files.

High-performance computing facilities, runtime (months), proper software environment, and training in use of the code, or in the use of the visualisation software, are not provided.
