The preferences define the initial values for new simulation processes. You can control the
values after you create the simulation process using the Simulation Process
Properties.
- Use fixed seed
-
Manually specifies the seed to an integer value in the Number of
seed field. The seed is used to initialize a random number generator used
in various adapters (for example, optimization genetic algorithms and stochastic
methods). If this option is not selected, the seed is determined randomly.
Typically, you would specify the seed to be a fixed value when you run a process
multiple items and remove the randomness to compare results consistently. You can also
specify the seed value for individual process adapters that use this option (for
example, optimization) using the adapter's editor. The adapter-level seed setting always
overrides the level setting of the simulation process.
- Default logging level
-
Determines the level of messages processed for each job executed. You can define a
threshold for the severity of messages to receive information on that particular level
and all levels below it. Processing more levels of log messages can impact how fast your
simulation process executes.
The following levels are available:
- Debug. These messages are intended for debugging system or
adapter code. Typically, these messages are meaningful only to program developers.
This level can produce a large quantity of messages that can affect system
performance. This is the highest level. Selecting this option sends all five types
of messages to your log file.
- Information. These messages contain routine status or other
informational items that are not generally significant.
- Warning. These messages indicate a condition to be aware
of, but generally do not indicate a failure.
- Message. These messages contain information pertinent to
the app run by the adapter. Typically, these messages are related to the status of
the execution.
- Error. These messages indicate an error condition caused by
usage, operational data, or some other condition that can be corrected.
- SysError. These messages indicate a software system
failure. They may indicate that some part of the infrastructure has become unusable
(for example, a database has gone down) or they may indicate a programming error.
Report these errors to system administrators for analysis. This is the lowest level.
Selecting this option sends only system error messages to your log file.
By default, This preference is selected.
- License pool
-
If you are connected to a cloud server, specify the License
pool.
This preference specifies the license pool that manages the execution tokens for jobs
that are using 3DOrchestrate. The default license pool is the pool to which your native app is connected. If you
select a license pool other than the default, the job execution uses the licensing
tokens from the selected license pool; however, the job execution takes place on the
private 3DOrchestrate station that is connected to the same license pool on which you submitted the job.
Only the license pools to which you have access are listed.
This option is available only for execution servers on the cloud. See your system
administrator if you are unsure about which license pool to select.
- License
Mode
- Determines the licensing model to be used to check out tokens or consume credits:
- SimUnit tokens
- Simulation tokens (On-premises only)
- Compute tokens (Cloud only)
