contact force on a surface

Status: Gathering Support
by Autodesk Support on ‎01-23-2017 07:51 AM

Would like to have a command to get the contact force on a chosen contact surface. I envision something similar to the "SPC Summation" for constraints. (See attached)

 

Note that the .LOG file gives the total normal and shear force, but there does not appear to be way to correlate the surface numbers in the .LOG file with the surface contacts defined in the model.

 

2D elements

Status: Gathering Support
by Advocate alain.benchissou on ‎02-03-2017 01:13 AM

Hi

 

 

It could be very interesting to have 2D elements available

 

    - 2D plane (stress and strain) 

    - axisymetric.

It appears to be available in the solver, but in the GUI, the doc does not indicate anything...


Thanks

 Hi,

 

A couple of our customers use a single seat for 2-3 people.

 

They have to shut Inventor down in order to allow another user to pick up the license.  

This can be quite troublesome when they are in full flow with multiple designs loaded.

 

A better solution would be to make In-CAD only pull a license when the Autodesk Nastran In-CAD environment is entered, and to release when they exit by pressing the Finish Autodesk Nastran button.  This way neither user's workflow is interrupted.

 

A less ideal alternative would be to allow the add-in to be unloaded.  The option to uncheck via Add-ins is greyed out if already Loaded.

 

Regards,

Scott 

 

 

In most cases when I want to duplicate an analysis, I dont not want all idealizations, load, boundary conditions to be duplicated as well... this just floods the model tree...

Hello,

 

In the cases we launch analysis with 1/2, 1/4 or 1/8 of real part geometry (using symmetry planes in order to have lighter meshes), it would be so useful  to mirror the with respect the symmetry planes used for apply the symmetry constrain.

 

Thus, we would be able to visualize the whole deformed part.

 

This could be applied also for axisymmetrical parts.

Delete temp folder

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

Hi

 

 

Even when making non linear analysis, the default deformed parameters are set to a non real one and with a factor of 10.
For large displacement, it is very confusing when seeing results during the solving.

Setting it to actual and a 1 factor, should be more consistant.


Thanks

 

Typically I work in mm & netwons so the stress comes out in MPa.  Sometimes however in more complex setups I use pure SI units to make sure I don't mess up material properties etc.  It would be nice if I could still output in MPa instead of Pa and mm instead of m or even ksi and inches for my American clients.

Something as simple as a manual scale factor during plot setup

 

mesh settings used

Status: Gathering Support

I think it could be more interesting to have a clear menu or option to indicate the mesh engine will use the global mesh settings or the table.

 

 

Adaptive mesh refinement

Adaptive mesh refinement is a very nice feature within the Inventor stress analysis module - could be useful to have in In-CAD as well

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.

Forum post (Quad Meshing for Solids)

 

I would like to be able to create 3D brick elements when solid meshing Inventor or SolidWorks parts/assemblies.

Gravity

Why not show standard gravity value?

 

As it is in Sim Mech...

solid and shell von mises stress in same plot

Status: Accepted
by Contributor jesper on ‎11-19-2015 04:19 AM

In Inventor Stress analysis I can display Von Mises stress levels for solids and shells in same plot, but not with In-CAD?

 

Shell von mises plot (solid stress levels not displayed)

 

Solid von mises plot (shell stress not displayed)

This is a great suggestion!  We will research this and see what can be done.

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.

When the analysis units are changed, reflect these altered units in the material properties. At present they are not.

Share Results - 3D pdf?

Status: Under Review
by Enthusiast RichardOliver4462 on ‎10-07-2015 04:53 AM

Create the ability to share the results plots with another party that does not have Inventor / InCAD. Perhaps by enabling 3D pdfs to be generated for the contour option currently displayed. This would enable another party to receive a number of pdf files as appropriate for each contour chosen, and rotate / zoom in as required.

Status: Under Review

We are researching options for this.  Stay tuned!

 

Thanks,

Failed mesh indicater

Status: Under Review
by Enthusiast davesm on ‎04-01-2015 04:42 AM

I would like to have the program indicate where the mesh fails. This would save a considerable amount of time. My work around is to open the model in INV stress analysis and mesh the model. Locations of areas where the mesh failed are shown.

Nastran In-CAD for Fusion

Status: Gathering Support
by Participant 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

make excluded components visible

Status: Under Review
by Contributor jesper on ‎11-19-2015 03:15 AM

In In-CAD 2015 it was possible to display excluded components together with the results plot - can we have this feature in 2016?
