Cluster partitioning method. Choose from mesh ordering (mo), nested dissection (nd), or weighted nested dissection (wnd).
|
|
|
Cluster storage format. The single format does I/O only from the root node, while the shared format does I/O using distributed I/O operations. The shared format requires that all nodes have access to the same storage area and the same temporary storage area.

Path to a workspace directory for storing internal workspace information. The workspace directory is by default a subdirectory to the preference directory. However, the default location of the workspace directory is not affected by the -prefsdir option. The workspace directory is cleared when COMSOL is launched.

You can also specify the number of cores and the use of the scalable allocators as preferences on the Computing>Multicore page in the Preferences dialog box. To specify the number of cores manually, select the Number of cores check box to enter a number in the associated text field. By default, all cores are used. The preference option for the scalable allocator is called Optimized for multicore. If you want to choose another memory allocator than the default setting, select the Memory allocator check box and the choose Native or Optimized for multicore. To control the scalability assembling mode, which can be useful even when running on a single node, select the Memory scalability optimization for assembling check box. You can then select Off (the default, for no scalability mode), Matrix for activating scalability mode only for matrix assembling, Vector for activating scalability mode only for vector assembling, or All for activating scalability mode for all cases. You can also control these options with a command-line argument, -memoptassem.

Always make sure that untrusted users cannot access the COMSOL login information. Protect the file Library/Preferences/COMSOL/v62/login.properties. This is important when using the COMSOL Multiphysics client–server configuration. Alternatively, start the COMSOL Multiphysics server with the -passwd nostore option, and clear the Remember username and password check box when connecting to the server. This ensures that your login information is not stored on file.

Do not compute the model. This option is useful if you, for example, just want to run -clearsolution or -clearmesh on a model that already includes a solution or mesh and then save it, without a solution or mesh, without computing the model first.

Compact the history before saving. This argument can be useful, together with -clearmesh and -clearsolution, to reduce the size of the saved file.

Specify where to store the runtime when running the application. The default option is the platform’s default location. The ask option asks the user for the location of the runtime when running the application. The <path> option provides a location where the runtime should be unpacked and stored. Only specify a path when compiling for a single platform.
