Edit Solver Parameters dialog box

Output File UnitsAppears for Potential Flow solutions.
Units (Force)(Length)(Mass)	Specifies the units of force, length, and mass for the simulation. You use the drop-down to select standard unit settings.
Solver Executable Location
Target Operating System Family	Specifies the operating system for the solver script. Use the solver script file that corresponds to the selected operating system. Systems available are:Autodetect****Windows operating systemUnix operating system
Use Environment Variable UGII_PRESOLVER	Select the Use Environment Variable UGII_PRESOLVER check box to use the location of the executable as specified by the UGII_PRESOLVER environment variable.By default, this variable is defined in the ugii_env_ug.dat included with the installation. This variable points to the pre-solver executable in the simulation\PreSolver directory within this software's installation directory. With the UGII_PRESOLVER variable, you can customize it to point to different installations.
Solver Location	Appears when the Use Environment Variable UGII_PRESOLVER check box is cleared.Specifies the script location. Use the Solver Location box to manually specify the directory path or Browse to select or create a directory.Note: The software does not validate the script location when you create an input file with Write Solver Input File in the Export and Solve dialog box. Therefore, you can also enter a non-existent script location for Solver Location. The script can be located on a system that you want to use for remote solving.For more information about Write Solver Input File, see Export and Solve dialog box.
Use Environment Variable UGII_SYSNOISE	Appears for Potential Flow solutions.Select the Use Environment Variable UGII_SYSNOISE check box to use the location of the executable as specified by the UGII_SYSNOISE environment variable.By default, this variable is defined in the ugii_env_ug.dat included with the installation. This variable points to the pre-solver executable in the simulation\PreSolver directory within this software's installation directory. With the UGII_SYSNOISE variable, you can customize it to point to different installations.
Solver Location	Appears for Potential Flow solutions and when the Use Environment Variable UGII_SYSNOISE check box is cleared.Specifies the script location. Use the Solver Location box to manually specify the directory path or Browse to select or create a directory.Note: The software does not validate the script location when you create an input file with Write Solver Input File in the Export and Solve dialog box. Therefore, you can also enter a non-existent script location for Solver Location. The script can be located on a system that you want to use for remote solving.For more information about Write Solver Input File, see Export and Solve dialog box.
Solver Temporary Directory Location
Specifies the location of the directory where the pre-solver generates input and output files, including results and log files.
Use the Model Directory	Select the Use the Model Directory check box to generate solver files in the same directory as the current simulation.
Solver Temporary Directory	Appears when the Use the Model Directory check box is cleared.Use the Solver Temporary Directory box to manually specify the directory path or Browse to select or create a directory.Note: The software does not validate the solver temporary directory when you create an input file with Write Solver Input File in the Export and Solve dialog box. Therfore, you can also enter a non-existent location for Solver Temporary Directory. The directory can be located on a system that you want to use for remote solving.For more information about Write Solver Input File, see Export and Solve dialog box.
Advanced Settings
Memory (GB)	Specifies the total maximum RAM used by the solver. This will be reflected in the matrix decomposition computation.
Number of Threads (smp)	Specifies the number of threads to use in parallel multi-threading (Nastran smp - Shared Memory Parallel) for solving the solution.
Job Control
Run Job in Foreground	Lets you control whether the solution runs in the foreground or background. You can:Select the Run Job in Foreground check box to run the solution in the foreground so the software is unavailable during the solve. Clear the Run Job in Foreground check box to run the solution in the background so you can use this software while the solve is running. You can even close the software.
