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.
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE
studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Use the Plot tool to track converged and derived solution behavior in real
time.
Open the Plot tool in the following ways:
Select the Plot icon on the Solution ribbon.
From the Run Status dialog, right-click on an
AcuSolve run and select Plot time
history from the context menu.
Convergence plots for residual ratios and solution ratios are available by
default.
If AcuSolve is still running, the
plots update in real time to track the solution progress.
Create Plots
Select data of interest to plot and then add it to a preview plot. Once all curves
are added to the preview plot, the plot is available for placement on the plotting
canvas.
In the Plot Manager, click to create a new plot.
Optional: Click to import an existing plot definition.
This allows you to read results data from multiple AcuSolve runs at once and use them as data sources for
your plats.
Define the y-axis.
Select a data type from the Model pane.
Run Data
Contains the general simulation parameters such as Time,
Time Increment, CPU Time and Elapsed Time.
Residual ratio
Contains the residual ratios for each of the flow parameters
such as pressure, velocity, eddy viscosity and temperature.
These ratios can be plotted with three different options
Initial, Final and All.
Solution ratio
Contains the solution ratios for each of the flow parameters
such as pressure, velocity, eddy viscosity and temperature.
These ratios can be plotted with three different options
Initial, Final and All.
Surface output
Contains surface integrated values of variables such as
pressure, momentum, mass flux and wall shear stress.
Surface statistics
Contains the surface statistics of minimum and maximum of
variables such as pressure, momentum, mass flux and wall
shear stress.
For residual and solution ratios, select a residual type.
Initial
Provides the ratios at the start of each time step.
Final
Provides the ratios at the end of each time step.
All
Provides the ratios for all of the staggers within a time
step.
For surface output and statistics, select a variable
sub-category.
Direction orientated variables, such as velocity, momentum, and shear
stress require you to select a coordinate direction.
Select the part(s) you want to plot.
Optional: Click the x-axis to cycle between values.
Optional: Change the name of the plot using the text box below the preview.
Click Add Curve to add your plot to the preview.
Select one of the following:
- Plot previewed curves and continue creating
plots.
- Plot previewed curves and return to the base
view.
- Delete preview and return to the base view.
- Clear the preview.
Plot User Defined Functions
Use a python-based scripting language to define new functions from existing curve
data.
In the Plot Manager, click to create a new plot.
Do one of the following:
Click .
Right-click on User Defined in the Model Pane and
select Create New.
Enter a name for the function.
Enter a python script in terms of "Get", "time", "step", or "value".
For example:
cpu = runData(1.'Run Data'.'CPU Time') elapsed = runData(1.'Run Data'.'Elapsed Time') value = cpu/elapsed
or
value = 1 + step
Select data types, components, and parts to add to the function if
needed.
Note: Click to insert the field into the UDF editor with
the correct syntax.
Select one of the following:
- Add the function to the plot
preview.
- Save the function.
- Delete the function.
Tip: Click
to edit a UDF.
Edit the Plotting Canvas
The canvas layout can be changed to accommodate more plots on a given page.
Additional pages can also be created.
In the base view of the Plot Manager, click or
to add/delete pages then use the arrows to cycle between them.
Use the drop-down on the far right to change the layout of the page and allow
for more or less plots.
Double-click on an empty plot to select it, then right-click on a data set and
select Make Current to plot it.
You can also edit, rename, delete, and export by right-clicking on data sets
and variables.
Scroll to zoom in or out on a plot and right-click and drag to pan.
Click to return to a fitted view.
To edit display properties, right-click on a curve, plot, or variable.
