Add Total Pressure to the Bulk Calculator

Status: New Idea
by Abelry on ‎07-21-2014 07:50 AM

Calculating the mass weighted total pressure is important for internal compressible problems, valves turbines and compressors.  It is the desired variable for compressor companies to run sub models to optimize the inlet and outlet transition regions before and after the compression stages.  Last week I meet with a compressor company that is happy using another CFD tool for the compressor stage design but only have 1 user.  For the inlet and outlet transitions they are don’t more design work and feel that our CFD is a better fit and cost effective to roll out to 100 design engineers to right size new products to address new market needs.  To fit into their workflow they need to know the Total Pressure at the outlet and map effectively to their current compressor CFD tool.

I would like to have the possibility to set the legend acording to the max and the min value on a section plane:

 

It would make it easy to see details wich otherwise remain hidden...

User Interface Suggestions

Status: New Idea
by Contributor nmuoio on ‎12-11-2013 04:18 PM

After using the current user interface for most of this year, I have compiled a list of suggestions that I believe would be improvements.  Much of the list are features that I miss from the older interface.  Although the items seem fairly minor, I believe they could increase the efficiency of the UI.

 

  1. Add Coordinate Axis to View Cube.  I personally dislike viewing the axis in the middle of the model, and change the default setting for this axis to be off.  It would be nice if an axis could be attached to the View Cube, as was in the classic interface.  It would also be convenient if the colors of the x,y,z axes would match the colors of the x,y,z velocity curves in the convergence plot.
  2. "Show Outlines" for results planes off by default.  When I work with results planes the first thing I do is turn off "show outlines."  The outlines are useful on occasion, but most of the time I prefer not to see them.  If I could change a setting such that the outlines are "off" by default, that would eliminate a lot of unnecessary mouse movements.
  3. Hot keys.  Assigning hot keys to commonly used commands would be a convenient time saver.  Although the classic interface did not have user assigned hot keys, it did have a hot key that I found very usefull ... the "f" key was Zoom (Fit All).  I still find myself hitting the "f" key, expecting to zoom out.
  4. Selection List window default to on.  I refer to the Selection List window a lot when creating a model, particularly when working with multiple entities.  I'd like to be able to set to Selection List window to be open by default.

The efficiency of the UI can be greatly improved by added a few customization features that would allow the individual analysts to personalize the software to match their particular workflow.  It wouild be good if others would post their suggestions, as well.

Spray Nozzle Evaporative Cooling

Status: New Idea
by msmith120 on ‎06-19-2014 07:29 AM

I would like to be able to simulate a nozzle that sprays water into an air stream. Ideally I would be able to view evaporation of the water into the air stream (evaporative cooling) and condensation of moisture from warm air onto the cold droplets of the spray (dehumidification).

Mapping Velocity/Pressure results

Status: New Idea
by CJunxian on ‎07-30-2013 06:32 AM

Is there a way to map the velocity/pressure results from an outlet, and subsequently map the result to an inlet of some other components/systems?

 

An example of application would be: 

a centrifugal pump is simulate to obtain the simulated fluid's behaviour (velocity/pressure) at the outlet.

Next, the same results are mapped to the inlet of a rotating fluid tank that it is attached to. 

 

Of course, both the simulation can be done in one go, but if there are 2 or 3 different configurations for the fluid tank, but all are attached with the same pump design. It would save a lot of time by just applying the mapped results from the first simulation.

Results Plane Features

Status: Solution Provided
by tdannen on ‎02-11-2014 06:54 AM

Currently results planes list in the design study bar but are not linked to the display window. When multiple planes are in use, it would be beneficial to be able to select the plane from the design study bar and initiate edits on the plane and have the selected plane highlight in the display window.

 

Defining a results plane as a summary plane should be toggled option. Currently a plane designated as a summary plane cannot be undone.

 

 

Status: Solution Provided
Thanks for the feedback. Planes are now linked from the Design Study Bar to the model display. You can right click and edit the planes directly from the tree. Please check it out in CFD 2015. While you still wont be able to toggle a summary plane, you can now remove them from within the results environment without having to go to the Decision Center.

Bulk Calculations Over Time Steps and Save

Status: New Idea
by Active Contributor sgold on ‎02-10-2014 08:10 AM

Very Simply.  Calculate the Bulk calculations over all or some Time steps and allow Export to a file.

 

It is VERY tediuous to have to change each step then type or write down the results.

 

The next step is to chart these results over time, but just getting the data and doing the results in excel would be a first, much needed, step.

show/hide in setup phase from panel bar

Status: Under Review
by Distinguished Contributor DWhiteley on ‎10-11-2013 01:29 AM

Please add the show/hide functionality for volumes in the browser when in the setup phases. With ctrl/shift select as well.

 

This would be useful when trying to hide volumes that are very small and can't easily be selected in the graphics interface.

There needs to be some consideration taken to allow for reorganizing/regrouping analyses between different Design Studies.

 

I currently have a Design Study that has 4 analyses in it.  I coned one of the analyses and ran it.  When the results were complete, I tried to open it but the system crashed.  I was unable to ever get the results to load.  I could delete the folder with this analysis and get the Design Study to open, but then I didn't have my results.  Since it took quite a while to set up the analysis, I used the support file to run the analysis. I was then able to see the results in this new Design Study. 

 

So here's what I'm left with...  2 Design studies on the same project, all caused by your system not being able to see result your system generated.  Apparently at this point there is no way to move the analysis that worked and was viewable into the old Design study.  Thus, I cannot use any of the Summary features or any comparative analysis tools you provide and I have to manage 2 files instead of one.

 

As a side, there is also, no easy way to get my 15 cloud credits back when I'm not able to open the analysis files....

I'd like to be able to run a CFD analysis involving heating of a piece of equipment. We are expecting non-uniform temperatures throughout the body and want to understand what sort of stresses will result.

 

Do others see value in running a Simulation CFD analysis and using the temperature field as a load in a stress analysis in Simulation Mechanical?

easy way to show or hide trace lines

Status: New Idea
by dts on ‎10-17-2013 06:42 AM

Dear Development,

 

It would be nice to have an easier way to show or hide trace lines. At this time I'm quite sure that a lot of people just throw away the flowlines because they don't know that you can put them on hidden (and it needs a lot fo clicks).

 

I was thinking on adding a split in the plane selection box (see image attached) because traces are made in that environment:

Sorry about my writing in the screenshot :-)

There are times when a part is used many times at the assembly level that selecting all the surface cad entity groups is not feasible or would take too much time.

 

What the user would like to do is be able to assign the CAD entity group at the part level and have those entity groups be available at the assembly level for each instance of that part.  This way the assignment only needs to be done once.

Trace set export/save improvement

Status: New Idea
by matt on ‎02-01-2013 04:53 AM

I would like the ability for trace sets to retain their individual properties after a save/export action.

 

When traces are saved or exported it places them all in one trace set killing their separate trace properties. Upon reopening you cannot edit the sets individually anymore. Also when exporting they lose their properties in showcase and are all imported as one set of faceted cylinders. i.e. I cannot get a set of ribbon traces and a set of sphere traces in showcase, only one set of cylinders.

Keep Text alert contact number the same

Status: New Idea
by Contributor DelNegro on ‎01-15-2014 12:09 PM

I turned on text alerts to let me know when my analysis was complete.  The only issue is that the alert comes from a different number every time I get it.  Its a simple sequential number but it is pretty irrelevant and comes up as a number I do not know. When I got the first text, I set up the number as a contact titled "CFD Alert".  It would be nice if all the alerts came from the same number so I would know what they are just by looking at the contact.
