Merging two nodes

Status: Comments Requested
by mppkumar on ‎09-03-2014 10:34 AM

Some times we may need to merge two nodes and the resultant node should form at the center of merged nodes.

 

is it possible to have a check box and if it is checked the resultant node will be at the center of merged nodes

 

Thanks

Collapsed folders as default

Status: Comments Requested
by eknema1 on ‎01-27-2014 08:07 AM

When opening a project, all folders in the task pane expand fully by default.  In a project with a lot of studies, this can be a bit of a nuisance.  I usually have to collapse almost all the folder to get the most recent info visible within the window.  If the folders could reopen in the state (collapsed/expanded) in which they were when the project was closed, that would be ideal.  At the very least, making the default have a project open with all folder collapsed would be an improvement.

Hybrid Meshes

Status: Comments Requested

Hello all together,

 

to speed up the simulation, hybrid meshes would be advantageous.

 

For example Sigmasoft takes voxal meshes and this mesh is more tolerat of CAD problems. The calculation time for a compled Mould is very fast.

 

To decrease the preparation time and  computation time hybrid meshes can help.

 

It would be possible to simulat very large models in 3D.

Hi Michael and Harald, My personal goal is to remove 'meshing' as a skill we have to teach the user in order to get fast and reliable answers. And we do spend time every release to improve the meshing and the solvers, but this is certainly not a 'done' problem. I do want to provide a little context though. 1) Voxelation provides a very fast and robust mesh generation path. We actually developed what is probably one of the fastest voxel meshers available for other reasons, so we are very familiar with the technology. We did not develop it to replace our normal meshes as as there it comes with very significant sacrefices in appearance and run times (you generate very very large meshes). 2) Within Moldflow we can generate several different mesh types, and each works a bit differently, and depending on the starting geometry type, the meshing path may be different (this expalins why meshing on an STL or a Solid CAD model will give you different meshes on the same gemoetric part). Within the meshers there are typically a few steps that predeed or follow the 'mesh generation' like mesh imprinting and matching. These post meshing steps can take significant time compared to the brute mesh generation, but in the end pay back in better analysis results. For some pieces of some meshing paths we license technology (not Distine :-) ), but very significant pieces were developed internally and are continued to be developed. 3) In the last few releases (since 2013 I believe) we have improved the tolerance of the solver for dealing with meshes that are not pristine and perfect. Appart from this being a good idea, there is simply no way that we can guarantee that the initial starting geometry is good enough to create a pristine mesh. More work still needs to be done, but I have seen many customers spending too much time fixing the meshes up perfection, whereas the 'default' mesh would have given nearly the same analysis result. 4) Lastly, I agree that the meshing controls in Moldflow could use an overhaul. It's not as interactive as you would hope it would be. Thank you for your valuable input on this topic.

Shrinkage analysis for 3D

Status: Comments Requested

Shrinkage analysis should be available for 3D mesh, as most of the things are available in 3d mesh now, which were not possible in previous versions

Simulation of air cooling

Simulation of air cooling

 

1. Air as a coolant

2.Simulation of air sprayed cooling systems

Status: Comments Requested
I've heard the use of air as a coolant medium a few times recently. The main reason that for its use seems to be that air as a cooling medium has low pressure requirements and would allow very thin coolant cross sections. I'd be interested in hearing more on this. Could you provide more insight into 'air sprayed cooling systems'.

moldflow should be able to estimate the time for analysis.

 

when ever, we are launch an analysis, moldflow should be able to pop up tentative time to complete the analysis.

 

it should be based RAM/ memory / processor availble/solver settings and number of nodes/elements

I would like to have other people's perspective on this; if this is a significant amount of work involved (that we would for instance not dedicate to for instance accuracy) and the time estimate would be a very very rough ball park, it this worth doing?

In Options of synergy, default display tab.

 

There must be a option to 'set visibility/hide' to Triangle, node, tetra elements, surface & curves.

with existing options like solid, solid+elements, transparent, transparent+element & shrunken.

 

So that we can switch of the visibility to unwanted enities, when study is ready to run analysis
