Ansys EnSight: Brief Review - Part 1
Hello, this is Ertan from Ozen Engineering, Inc. In this video, we will review the Ansys EnSight post-processing tool. This is the first part of the series.
Loading Data
I've already opened the EnSight screen, and we're going to load the data. I'll start by opening one of my older files, which was a CFX simulation. This file represents the result of a CFX simulation.
If you're wondering about the geometry, it's an arctic arc geometry used to demonstrate a die washout with a scalar transport equation. For details on implementing a scalar transport equation, refer to the previous video.
Viewing and Manipulating Geometry
Upon opening the file, the face and corresponding volume regions are loaded. You can enable or disable the view by selecting individual parts or all parts and clicking to hide or show them. You can also hide or deselect specific portions of the geometry.
Creating a Cross-Sectional Plane
- Go to the Clips section, which opens a new screen.
- Select the direction to slice, such as the Z direction.
- Set the parameters, for example, Z direction to 150 and STP to 100.
- Generate the clip and color it using variables like pressure or velocity.
Visualizing Mesh and Creating Queries
You can visualize the corresponding mesh on the cross-sectional plane by clicking the gadget to specify line overlay color. Disable the mesh by clicking the gadget again.
Creating a Query or Plot
- Go to the Query section and create a plot.
- Select a variable to observe, such as a scalar.
- Choose the surface or area to observe, for example, the branch exits.
- Decide the method, like maximum over time, and create the query.
Animating and Saving States
You can create animations to visualize transient simulations. Add time annotations and adjust the scale and position as needed.
Creating and Managing States
- Create a new state and name it (e.g., state1, state2).
- Make changes to the view and redefine the state.
- Switch between states to view different configurations and plots.
Additional Features
Enhance animations with keyframes for rotation and other effects. Save animations as AVI files for sharing.
Adding Surface Flow
- Open the surface property editor and enable Show Flow Texture.
- Adjust the streamline length and contrast for better visualization.
Conclusion
In this video, we demonstrated how to:
- Read CFX data into Ansys EnSight.
- Create cross-sectional planes and visualize mesh.
- Generate plots and manage states for different views.
- Create animations and highlight features.
Thank you for watching. Stay tuned for the next video, where we will discuss further features.
Hello, this is Ertan from OZEN Engineering and this video is about ANSYS EnSight post-processing tool review - Part 1. I already opened the EnSight screen here and we're going to load the data. First of all, I'm going to open one of my older files which was a CFX simulation.
This is typically the result of the CFX simulation and I'll open that file. When we open the file, we see the faces and corresponding volume regions are already loaded. We can disable the view or enable the view by selecting individuals or all and then clicking hide or bringing them back.
We can individually hide or deselect certain portions of the geometry. As a first example, I would like to demonstrate how to create a geometry that is in the form of a cross-sectional plane. We're going to go to the clips.
The clips open a new screen and ask us in what direction we want to slice it. In this particular example, I'd like to slice on the Z direction.
We need to select the Z direction and then select 150. We're going to put the STP to 100. We've already emphasized that, and we're going to select hitment sub consistent. We can color this clip with different colors or select a variable to color it.
For example, I can color it with pressure, scalar quantity, or velocity. So let's go with velocity in this case. We can move the color palette and change the size of it, as well as change the format. We can also visualize the corresponding mesh on this cross-sectional plane.
We have to click the specify line overlay color and then hit okay. We can disable the mesh by clicking at this gadget. Let's take a look at how to create a query or a plot. We're going to create a query, write a plot, and select a variable that we would like to observe.
Let me select the scalar here. We have to select on which surface or where we would like to observe this quantity. I would like to observe the maximum values on this surface of the branch exits. We can play with the position and the size.
We can create the animation or just take a look at how the transient layer looks. We can also bring the time, at what timeframe we are at, even though we can understand from here. We have created a screen, which we call states.
We can name it as state one and then create a new state and name it as state 2. We can order them however we want to do. For this state, state2, we'll create a different screen so that we will see different options. We can split the entire screen into multiple regions.
We can select whatever we want. We can show the face using a scalar quantity. We can see how the animation looks from these different views. We can save this as a second state. We can make as many states as possible, and it's going to make the post-processing quite easy for us.
Let's add some other features to the animation on the screen. We will generate a rotation on this piece in the middle screen. When the animation starts, it's going to also rotate. We can save this and export the animation. In this state, I will disable this plot and the query and the plot at all.
We are on the clip plane. When we open the surface property editor, we can click show flow texture. We see now the streamlines are actually shown on the screen. We can play with the length and increase the high contrast. This might be also something nice to show.
In this video, we have seen how to read the CFX data into Ansys EnSight, create a cross-sectional plane, show the mesh, create a contour, and add a surface flow on it. We conclude with this video. Thank you for watching and stay tuned to the next video in the series.
