[using Ensight 10.1.2]
Hello,

My problem is the following:
I have a cylinder with a hot fluid flowing from inflow to outflow, hence flowing with a certain velocity.

I would like to plot the velocity profile along the whole longitudinal axis of this cylinder. I am able to do this by using the 'Pick Line Tool Location' >> By two points', to obtain a graph with the velocity profile. Now, I would like to have different consistent velocity profiles along the whole cylinder to view the entrance region and fully developed region of the flow. By 'consistent' I mean a velocity profile every x meters along the cylinder.

I have another question on this matter and the use of a 'Clip Plane' ('Create >> Clips).
With a Clip Plane, I can view the velocity ( or temperature ) profile of a surface. The Clip Plane comes in handy as I am able to move it in the longitudinal direction to see how the considered property varies.
I would like to know if it is possible to attach an axis (with the 'Pick Line Tool Location') on this Clip Plane to have a graph that plots the considered property and that changes when I move the Clip Plane.

Thanks in advance,
Jorge

Jorge,

Those are certainly possible in EnSight. If you want to remain using the Line Tool, then the best option is to ensure that you first create a Clip from the Line tool, and query against the Clip Part, and not the Line Tool. You can make the Clip Interactive to dynamically follow you.

Using the XYZ clip method is easier, if your clips are aligned to an axis.

The Link below is for a short Video explanation of this, and how to address both the items that you raised:

Hello Kevin,

Thank you for your help, it is really getting me through my problem.
The video is very clear !

I was a bit wrong in explaining the situation as my case is actually a cylindrical tube and not a pipe.
But nevertheless, I've managed to apply what you explain in the video for this case by choosing the Clip plane along 'T', and then modyfing the axis along which the plane rotates.
This means that I can rotate the Clip plane to see the velocity profiles in the radial direction on different longitudinal positions.

Thanks for solving my problem,
Jorge

Hello,

I have a question on this matter.
I followed the step in the video you made.
What I would like to do now is to get the datapoints of the queries to use them in Excel for further manipulation.
How can I do this without having to select each graph with a right mouse click -> data -> copy to clipboard ?

Is it possible to get those datapoints by manipulating the objects in the 'Plots/Queries' tab?

Or is it possible to use Ensight instead of Excel for manipulation?
For example: having all plots on 1 graph?


Thank you in advance,
Cedric

In recent versions of EnSight, you can select all of the queries in the queries/plotter object list, and there is a right click option to save all queries to csv file at once.

However, depending upon what you want to do, you can continue to use EnSight for graph manipulation. For example, if you drag/drop a query onto an existing plotter, that query will be added to the plotter (showing you multiple queries on a single plotter).

Hello Kevin,

This is what I needed, thank you !

Dear Kevin,

Is it also possible to do the same, but different *.case files ?

Can I gather data from different .*case files and plot those in one plotter?


Best regards,
Cedric

Yes, you can have queries from multiple cases displayed in a single plotter. The queries and plotters in EnSight is separate from cases (sort of like annotations and viewports), so they don't have any inherent case-related restrictions.You can select queries from multiple cases and export those as well in one operation (newer versions of EnSight). These client-side features tend to be relatively free of the constraints of case-related items (multiple cases have multiple 'ensight servers' but only one 'ensight client').
