Hi,

 

it could really help to have a plot/log during analysis to see the iteration number and convergence problems.

 

Actually you need to open the intermediate log manually.

 

It would save a lot of time for convergence problems

Hi,

 

it would be nice to have a button to launch jobs in ansys/abaqus for AME rather than command shell

Hi

 

 

Users would like to include a scale factor when recovering the warp of a part.
Especially to taken account of the shrink compensation (difference between CAD and mold dimensions).

I understand it is causing an issue because of the relative MF stresses.


So, when we could diretctly get the stresses in Helius, maybe, it could be applied ? only on the strain field..?

 

 

Thanks

mapping

by alain.benchissou on 11/24/2016 8:53 AM

Hi

 

 

People would like to

    - be able to look at the mapping quality through the thickness of the FEA model (in Helius GUI)

    - maybe have also the hand of the quality of it, ie why not having an option to use FEA element formulation with more Gauss points (so avoiding of remesh finer the FEA model that is very penalising for users) ; actually, the fact that the mapping is totally a "black box" leads to the customers for non controlling at all this step..and so is frustrating them...

Hi

 

 

Great now feature about weld lines option to use for mechanical analysis.

 

A lot of customers would like to use this feature for midplane models


Thanks

In AME to rotate models we use middle mouse button in but not in manual alignement tool we have to use left mouse button. To translate in AME we use left button and middle in manual alignement tool.

 

It could be usefull to unify.

Helius PFA support the FEA with ANSYS and Abaqus only.

 

Please support the Autodesk Nastran, Autodesk Nastran In CAD and Autodesk Simulation Mechanical.

It will be great to use COMPA as an add-on with Simulation Mechanical. Because Simulation Mechanical is the most user friendly stress-strain simulation software available.

Thanks

I'm having a very strange problem with the xstf.exe. This is a standalone program (outside of being partly dependent on Abaqus inputs to get an inp file) correct? Everytime I run xstf on a file right now, Windows claims it needs to be closed or debugged. Could this be an installation issue? I've checked multiple times that the user defined material (it's uni-directional composite so it's pretty easy to define) is being called is correct and have changed where it lives (the asca.env file was changed to reflect the changes) to see if there was some permissions problem because I am on a university computer, but I've not gotten it to work. I've tried making the material through the gui as well as directly with a batch file, and that hasn't helped either. The picture shows the issue it throws when trying to run it. Thanks for any of the help given...

Per "Modeling Damage Tolerance in Composite Materials"
http://help.autodesk.com/cloudhelp/2015/ENU/ACMPAN/files/GUID-FCEC8F7F-46AE-4A2A-8A16-0523E4372DDD.htm

 

It is possible to specify initial conditions for element state variables (SDV1) but not the state of individual layers or integration points. When modeling each ply discretely with 1 element, this is sufficient. However, when using shell elements this only gives the analyst two options: All plies have matrix failure and all plies have fiber failure. I would like the capability to say the first 3 plies have fiber failure and the last 6 plies have matrix failure.

 

This will allow me to start my model with better accuracy in my initial conditions.

 

Also, please see my comment that I added to the help article above.

 

Thanks

When you allow ASCA/Helius to take control of the convergence in ABAQUS (*CONTROLS) - if the solution gets into a repetitive pattern it will not abort this and will just carry on until the 1000 iterations has been calculated.

 

Can you add a detection for a repetitive SDI/equilibrium pattern?

Hi Dean,

 

In ASCA 2014, is it possible to run the Material Manager in "Batch Mode" within Linux and access the new material options that are available in the GUI?

 

More specifically, are there any new commands for the different weaves? Chapter 5 of the Material Manager Users Guide for Batch Mode processing makes no reference to these new material types and furthermore, the material output seems to be a v5.5 type material.

 

Thanks

Silvano

Reduce xSTIFF runtime

by dean.rose on 08/06/2013 1:05 PM

xSTIFF takes much longer to run in v5 than in v4.  Can anything be done to reduce runtime for large input files?

When xStiff is run, it significantly modifies the "layout" of the input file. For example, whitespace is deleted, letters are capilized, etc.

 

Ideally, xStiff would only add the stiffness parameters to the input file and the remaining bulk of the modified input file would be identical to the original input file.
