Visualizing the Non-Default Parameters in SOLIDWORKS Flow Simulation

By Suman Sudhakaren on

When it comes to visualizing the flow simulation results, SOLIDWORKS Flow Simulation offers variety of tools and options. For plots, we can go beyond the standard list of parameters and customize the list to enable more parameters that do not originally appear in the default parameter list. For this we can click on the “More Parameter” and access the list that allows us to easily turn on visibility of the parameters not enabled by default.

Add parameter option

Some of the available parameters listed there may not be relevant to our analysis case. For example, we may want to visualize parameters such as Humidity ratio, thermal resistance or Reynolds number depending upon analysis objectives of our Flow Simulation project. For these types of parameters, SOLIDWORKS Flow Simulation’s Engineering Database provides us the option to use Custom Visualization Parameters.

We can create custom result parameters using basic mathematical functions with specified parameters as variables.

These can be visualized in cut plots, surface plots and iso-surface plots. These can also be used in the XY-plots as well as point, surface, and volume parameters tables.

Listed below are instructions to specify a custom visualization parameter:

  1. In the Engineering Database tree expand the ‘Custom Visualization Parameters item’, right-click the ‘User Defined’ item and select ‘New Item’.

Custom - Visualization Parameters - add new item

  1. Under the ‘Item properties’ tab type the parameter’s ‘Name’ and, optional, ‘Comment’.
  2. In the ‘Formula’ row, browse for and specify the parameter definition through the ‘Visualization parameter to add’ and using the calculator-style buttons, complete the definition of the equation.

file folder open with tabs for instructions on solidworks flow simulation

  1. Go back to the ‘Item properties’ and select the appropriate ‘Unit’ or ‘Non-dimensional’ if no appropriate unit is listed.

folder with text options listed

  1. Click ‘File’ > ‘Save’ and close the database.

Note that specifying a custom visualization parameter in the Engineering Database does not add the newly defined custom parameter automatically to the list of visualization parameters. We will have to make custom visualization parameter available for visualization in the ‘Customize Parameter List’ dialog box.

In the image below, after an external analysis run was completed, custom visualization parameter -Reynold number was specified. Once this parameter is added to the list, it is available to be selected in cut plots, iso-surface plot etc.

Another example of Humidity Ratio defined as custom visualization parameter is shown the image below.

We hope you can utilize the power of custom visualization parameter option to gain even more valuable insight to your SOLIDWORKS flow simulation projects.
