Define nodal initial conditions for the simulation. You can define nodal initial conditions on the nodes of selected
surfaces and solids, nodes within zones, and nodes of solids on the side of a plane.
Use the Run tool to define run settings and submit an
AcuSolve job.
From the Solution ribbon, click the Run tool.
The Launch AcuSolve dialog opens.
In the Run definition section, define a problem name, a run directory, an
AcuRun installation path, processes, and the
number of processors.
Optional: Activate the Automatically define pressure reference
option.
If this option is on and there is no inlet/outlet type boundary defined, a
zero pressure condition will be applied on the nodes of the largest volume cell.
This is required for natural convection problems.
Optional: In the Default initial conditions section:
Define default nodal initial conditions and parameters.
If any parameters are defined in the Initialize tools, they will take
precedence.
Activate the Pre-compute flow and
Pre-compute turbulence options.
If these options are on, a flow field will be initialized by solving
Stokes equation. It will be a more relevant flow field but it will take
extra computing time.
Note: For variable density material models, it is
recommended to leave these options turned off.
Optional: Define simulation restart parameters in the Restart section.
Turn on the Restart from previous solution
option.
This restarts the simulation based on an already finished simulation.
It loads the restart data of the last time step of the defined run
before the current simulation starts.
Specify the name of the problem from which to restart.
If it is unspecified, the name of the current problem is used. The
current problem is provided by the command line option:
problem.
Specify the working directory of the problem from which to
restart.
This directory may be either relative to the current directory or an
absolute address. If the working directory parameter is unspecified, the
working directory of the current problem is used. This directory is
given by the command line option:
working_directory.
Activate the Reset time step option to set both
the step number and time to zero.
If off, the step number and time from the previous run are
used.
Click Run.
The Run Status dialog opens.
Once the run is
complete, the status icon turns to a green check mark.
Optional: Right-click on a job and select View log file to monitor
solution progress.
Write Output
While an AcuSolve run is in progress, right-click
on the job in the Run Status dialog and select
Write output to add the results at the current time
step to the output directory.
Stop an AcuSolve Simulation
While an AcuSolve run is in progress, right-click
on the job in the Run Status dialog and select
Stop to terminate the run.
