To set up the sequencing of configurations in a simulation, you need to define a configuration for each step in the simulation. Typically, there is a configuration for each analysis in the simulation. You are required to define at least one activation condition for each configuration. You set up the desired sequencing of configurations in a simulation by your choice of activation conditions. For each required configuration:
Create the configuration.
Set the name of the analysis to be associated with the configuration.
Create the required number of activation controls for the configuration.
Set the activation control option to activate the configuration at the start of the simulation or following the completion of another configuration.
Note that it is possible to have more than one configuration activated at the start of the simulation. You also have the option of specifying more than one activation condition for a configuration (for example, a configuration can be activated at the start of the simulation as well as at the completion of another configuration).
To control when remeshing is to occur, you are required to:
Create a remeshing definition.
Select the appropriate remeshing option.
Set up the remeshing activation condition.
Identify the location where the remeshing is to occur.
Supply any additional information required by the selected remeshing option.
To define how a CFX-Solver can be started, the number of settings that you need to define for Configuration depends on the case:
In some cases, you need only to specify the name of a CFX-Solver input file (
*.defor*.mdef). For cases that require initialization from previous results, you also need to specify the name of a results file (*.res).You can configure runs in serial or parallel:
Serial run is the default way of running a CFD case. During a serial run, all computation is done by a single process running on one processor.
Parallel run partitions the computation into more than one process and is done on more than one processor in a single machine (local parallel processing) or on more than one machine (distributed parallel processing). You also have the option of specifying how the computation is partitioned for a parallel run.
You can optionally select the system priority for the interpolator and solver computation as well as settings such as precision and memory allocation.
When you have finished setting the parameters for the configuration, click or to save the settings.
Details of the above steps are described in the next section.
