Organize Simulation Data Files

Status: Gathering Support
by Collaborator mwighton on ‎06-09-2016 07:17 AM

It would be nice if when a simulation is started a subfolder, in the file location, is created and all the data files are stored there. This way each subcase or different analysis has its own folder to go to rather than making the main file location bulked up. This would also allow for multiple simulations to be run at the same time on the same file and would keep the data files for each simulation, rather than nastran in cad over writing the already existing files.

Delete temp folder

I dont know why but the temp folder doesnt get cleared automatically, so it is getting big very quickly...

Nastran In-CAD for Fusion

Status: Gathering Support
by Contributor cfisichella on ‎08-03-2016 09:11 AM

Hi,

 

We can't pull the trigger on adopting Fusion until we know we can use the facilities that are in Nastran In-CAD. It would be great if Nastran In-CAD supported Fusion.

 

Best,

Chris

Various Enhancements

Status: Future Consideration
by Advocate RichardOliver4462 on ‎10-14-2014 01:33 AM

1. When constructing beam element models show the loads and reactions, as per image below (from Cadre).

 

 

 

2. Enable applied load vectors to be shown, image load vectors below (from Femap).

 

 

3. Allow cross-section to be shown in results window for beam elements as per image - stresses shown on cross-section (image from Multiframe)

 

 

4. Allow identification of surfaces / objects i.e. if you select a surface it should indicate the associated material / property in the Nastran tree. This would make a model with a lot of different composite materials (tapers for example) a lot easier to review. I appreciate that the mesh colours asscoicate with a property but this is not always easy to identify.

Thanks for improvement suggestions Richard.  Keep the suggestions coming!

Turn off load & comnstraint glyphs

Status: Implemented
by Collaborator DWhiteley on ‎09-30-2014 05:59 AM

The dsiplay of glyphs within Inventor are very slow.

Have a sngle button (like in Sim Mech) to turn these on/off

Status: Implemented

We've added a new ability to preview loads/constraints so they are not displayed by default.  We've also reduced the default number of glyphs to help with performance on large models.  There is also a setting under Default Settings>Display Options to turn off loads and constraints globally.  I hope this covers it, but if not, let us know and we can reopen it or open up a new one.  Thanks for the feedback!

Fatigue

Status: Gathering Support
by Collaborator DWhiteley on ‎07-29-2015 03:28 AM

Guys,

 

Add the fatigue endurance limit SN & EN material data from Sim Mech into Nastran In-Cad.

 

This would save having to locate such data when running a Fatigue analysis.

Multithreading

Status: Gathering Support
by Contributor damiendefrance on ‎02-09-2016 05:28 AM

Hi,

Is it possible to optimize the use of multicore processors ?
I invested in a 10 cores processor for thermal simulation with Autodesk CFD and I cry when I have to use Nastran in-cad.
Thank you.

Convergence

Status: Future Consideration
by Collaborator DWhiteley on ‎10-02-2014 08:34 AM

Convergence is one of the most useful tools in the Inventor FEA.

 

Perhaps look at including convergence tools within In-CAD?

 

Or are they there already & I can't see them?

HISTORY OF ANY QUANTITY

Status: Gathering Support

Hi

 

It would be very great to have a post processing for dynamics and non linear to make history of displacement, stresses and reaction forces.



Undo

It would be great to be able to use an undo function...

Summation of nodal results

Status: Future Consideration
by Enthusiast Madjerry on ‎02-23-2015 08:39 AM

I really need to be able to sum nodal results. For example aquiring the total contact force between two parts in welded contact. 

 

Selecting subentities (to use a Sim Mech term) would be great as well. So if I want all the nodes on a surface, all I have to do is select that surface and request all nodes on that surface be added to my selection set.  

Deformation Scale Preset

Status: Gathering Support
by Participant Tradeiteasy on ‎07-13-2016 05:59 AM

I am currently working with Nastran In-Cad 2016. I am mainly doing large deformation simulations. I find it very useful to see the intermediate results when running an analysis but I find it hard to interpret the results sometimes as the deformation scale varies sometimes for each step. Also when wanting to view the result of a large deformation I always find myself going into the options panel, clicking "Deformation Options" and then activating the "Actual" deformation.

 

It would be nice to have a general setting to control the result view up front. 

Nastran enhancements

Status: Gathering Support
by Observer keith.woodford on ‎09-15-2015 08:31 AM

In-CAD is a great product. The more i use it the better it i like it. But let’s get some enhancement ideas!

 

1 - Suppress a part from assembly on a subcase or top level analysis

2 - Apply a bolt pretention onto the surface of a part

3 - Allow glyphs to be turned on or off when applying a pressure load (it can get extremely slow and "laggy" on a complex model)

4 - Allow a method to select the adjacent face of a selection (some surfaces may not be easily accessed and may be at the same point as another surface but require individual separate selection)

5 - Brick elements


Great work guys!! :)

 

 

Inventor materials

Status: Implemented
by Collaborator DWhiteley on ‎10-02-2014 12:41 AM

I know there is a CAD button (in materials) but what about just being able to use the materials assigned to the Inventor model straight off?

Status: Implemented

If a force is applied to a solid body the arrows showing the load might not be visible, depending on the transparency of the model and the thickness of the solid. It would be useful if there was an option for the load arrows to either be 'pushing against the surface' or 'pulling'. This would enable the user to ensure the arrows were visible (option needs to be per load / not global)

Backup finite element data

Status: Gathering Support
by Contributor cfisichella on ‎08-01-2016 11:57 AM

A nice addition would be to provide crash protection by making a backup of the current user's work. I find Nastran In-CAD to be very stable and, unfortunately, it is forgiving when I don't save very often. But, that 1% of the time when it does crash, it would be great to not lose the work that is in the study.

Simulation Failure Dialog

Status: Gathering Support
by Participant Tradeiteasy on ‎07-13-2016 11:02 AM

When having a failed analysis I find it pretty annoying that i have to click back and forth from the output file to the model tree to find the actual cause of the simulation failure.

 

This could be more easily resolved by opening up a dialog after a failed simulation listing all the Warnings and Failures that occured during the simulation (with a button "show in context" to know in which context of the nastran output it appeared).

And to be honest: Failures make analysis work so lenghty. It would be really nice to have a direct link to the Nastran Error Code Knowledge base to get hints on how to resolve the error on that same dialog as well.

plotting of applied forces

Status: Gathering Support
by Advocate alain.benchissou on ‎04-21-2016 05:56 AM

It could be very interestinto be able to plot the applied force to each node

especially when using a variable load, that is not very simple to define is well setup or not

entity group

Status: Gathering Support
by Advocate alain.benchissou on ‎09-22-2016 05:51 AM

Hi 

 

 

Actually the group that could be created in NINCAD can contain only very limited type of entities.

If it could be extented to any kind, especially surfaces, etc...


That would help especially for composite orientations and other BC input.

 

 

I'm posting this for a subscription customer.

 

 

Having the ability to add bearing loads to shell elements would be extremely beneficial, both on a surface and a circular edge.
