32.1.59 File/Run...

The File/Run... menu item opens the Select Solver panel. This menu item is available only if you have started the solver without specifying a version argument.



Select Solver Panel


The Select Solver panel is used to specify the solver version or to run the solver on a remote processor. See Sections  1.2 and 31.2 for details on the use of this panel.

Controls

Execution   contains inputs for standard execution of FLUENT.

Program   sets the name of the program to be run. The default is fluent. You can use this option to specify a complete pathname if the program executable is not in your search path.

Version   defines the program version name: 2d for the 2D solver, 3d for the 3D solver, 2ddp for the double-precision 2D solver, or 3ddp for the double-precision 3D solver. It is updated to reflect the current choices under Versions. You can also enter a version name manually.

Option   specifies the directory path for the fluent_run script and any other information that is entered under Options. This field is updated automatically when you modify the settings under Options. You can also enter information manually.

Versions   contains options that control the version of FLUENT to be started.

3D   specifies the 3D version of the solver. The 3D version of the solver is specified when this option is enabled, while the 2D version of the solver is specified when this option is disabled.

Double Precision   specifies whether or not the double-precision version of the solver is to be used.

Parallel   specifies that the parallel version of the solver is to be started.

Remote Execution   contains the machine name, username, and user password for remote execution. The default is to run the solver on the same processor as the interface process ( Cortex).

Hostname   is the name of the remote machine.

Username   is the username at the remote machine.

Password   is the user password at the remote machine.

Options   contains a single option ( Load Path) for the serial solver, or several options if the Parallel solver is enabled. See Chapter  31 for details about the parallel solver.

Load Path   specifies the FLUENT installation directory.

Load Host   specifies a hostname for loading the compute node processes for the parallel solver. By default, compute node processes are loaded from the machine on which the solver was started. This item is available only when Parallel is enabled under Versions.

Hosts File   specifies the directory path and file name for the parallel hosts file. This item is available only when Parallel is enabled under Versions.

Processes   sets the number of compute node processes. The default value is set to 1. This item is available only when Parallel is enabled under Versions.

Interconnect   specifies the message-passing library to use. This item is available only when Parallel is enabled under Versions.

Default   selects the library that is generally applicable to any shared memory system or Ethernet cluster. For Myrinet or Infiniband clusters, the respective Myrinet or Infiniband options should be selected to provide the best performance.

Ethernet/Shared Memory   selects the library for use with Ethernet interconnects or shared memory machines.

Myrinet   selects the library for use with Myrinet interconnects.

Infiniband   selects the library for use with Infiniband interconnects.

Altix   selects the library for use with Altix systems (Linux/UNIX only).

Cray   selects the library for use with Cray systems (Linux/UNIX only).

Ethernet via sockets   selects FLUENT's proprietary socket-based library (not an MPI). This can be used as an alternative to the MPI-based Ethernet/Shared Memory option.

Run   starts the solver specified under Execution and Versions on the host specified under Remote Execution. If no host is specified, the solver will be run on the machine on which Cortex was started.

Apply   saves the current panel settings. These settings will be used if you start a solver by specifying a case file to be read.

Listen   tells Cortex to wait for a solver to be started manually. You can use this option to work around network security devices that prevent Cortex from creating a remote process directly. When you click this button, you will be prompted to start a solver with arguments -cx host:p1:p2, where host is the name of the host Cortex is running on, and :p1:p2 are two colon-separated integers indicating the port numbers being used. The solver should then be started from another system window by typing:

fluent version -cx host:p1:p2

where version should be replaced by the version that you wish to run, and the host and port numbers are as displayed in the FLUENT console window.
