Even if it interrupts calculation, he wishes the function which can be resumed from the middle.
When it is a model with many elements, it is because it becomes impossible for a job machine to use it all day.
Correspondence becomes impossible when a sudden analysis matter occurs.
There must be a recommended gate size in result or in LOG
1. It may be based on simple shear rate calculator(usually used Excel file)
2. It may based on shear rate results.
3. It may in table form/ circular size or rectangular sizes or Gate area.
There must be a provision to simulation cooling for ' thermoplastic overmolding' process
i.e 'Cool + fill+ pack + over molding fill + overmolding pack + warp' option
Probably Autodesk team should develope the same.
A proposal to simplify modeling Baffle features in a cooling system.
Currently, every baffle requires two separate lines to create a baffle. Users can either make a small V configuration or the two lines can be coincident. However, if at any time the nodes get merged on the baffle line then the solver interprets the baffle as a dead-end. This issue is especially problematic if using HyperMesh to generate a Moldflow mesh file.
Eliminate the second line needed to generate the baffle. The necessary pressure drop should be automatically calculated by the solver. The solver should also be able to tell which direction the water is moving based on the coolant inlet boundary condition. This is similar to other softwares on the market.
A SimCFD license is required for using Channel (3D) elements in a Cool (FEM) analysis.
It should be available without need of seeparate licence. It allowed user to import cooling channals 3D model
directly from tool design and do analysis.
The birefringence prediction moldflow does has gotten more accurate. It would be nice if it could take it one step further and run through the annealing portion of the process. The output would be the birefringence of the molded article after it has been heated and cooled to remove stresses. Seems like most of the information needed for the analysis is there. Looks like competitor software has this capability.
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.
Tiger strips/a surface defect, which often occurs in the injection molding, is characterized by a cyclic sequence of shiny and matt stripes at the flow front.
The physical cause of the occurrence of tiger stripes, is the re-melting of already frozen outer layers the thermally damaged material reaches the surface and leads to spots with a matter shininess in appearance.
It is possible with calculated plots with some relations, which is being used by some raw material suppliers.
Mold flow should introduce Tiger strips occurrence plot.
An Option to Dump results in between the analysis
In Sigma soft (competitor software similar to mold flow),
there is a option to dump the analysis in between, then stop the analysis. The, next time you open the study and re- launch the analysis, it will start analysis from where you stopped it.
In mold flow, we need similar option
i.e In Between; we can stop analysis instead of aborting and close the study. Then,we can re-run from, where we had stopped it. So that we can save time, incase we need to abort the analysis & re-run after some time,
Option to provide alternate trigger points for sequential valve gates
For example : If we have provided 4 cold gates for single hot drop, then flow front can reach early to any one of the cold gates.
Such case, we have run the one iteration to find out, which gate receives the flow @ first. Then in next iteration, we need to select the earlier flow reaching gate node as a trigger node.
Solution : Instead of that, if given an option like Node no1, node no 2, Node no 3( i.e 1,2,3). It should trigger valve open, which ever comes first.
Often, after starting a typical Cool(FEM)+Fill+Pack+Warp sequence, and while still at an early stage (i.e. Cool(FEM) running), one may change his/her mind on some options re further-on behavior; for example demand Warp to isolate the components. But when you change ANYTHING in Process Settings - regarless on whether it would really affect the current analysis state - we're presented with this familiar "Create copy", "Delete Results", or "Cancel" warning window. Less expereinced useers get frightened off by the necessity of running the sequence from scratch, so they cancel and do not introduse the desired changes...
It would be nice if the program "considered" the situation first, and only display the warning window if the user-introduced changes would invalidate the already produced/being produced results, or require the running analysis to alter the way it's executing. We the more experienced users know that if none of the above would happen, pressing "Delete" will actuallyNOT stop the sequence while introducing our changes to the way the consecutive analyses should execute.
Do you consider to introduce a more intelligent, context-sensitive use of the "Create copy", "Delete Results", or "Cancel" dialog window?
when defining a sequential gating and the valve gates are controlled by flow front and trigger nodes and the user is changing f.e. a location of a injection location AND is using "global merge" the nodes are renumbered.
afterwards all the triggernodes have to be defined completely new.
when simulating big parts with lots of injection locations this can be annoying.
or the filling behaves in a unexpected way because the triggernodes have changed. when simulation time is very long this is recognised to late.
solution 1.: lock the trigger node numbering. so the trigger node keep their number, even when all nodes are renumbered
solution 2: highlite the triggernode location by f.e. an clearly visible arrow
solution 3: change the way to define triggernodes or triggerlocations.
at the moment the user has to "remember" the trigger node. then swich to the property of the valve gate or change to the valve gate timing tab and enter the trigger node.
this could be more comfortable. like f.e. after highliting a node and rightclick, a menue could appear and the user could define "define this node for valve gate XY"
Everytime that I start SIM360 Moldflow the mesher and the solver are set by default as "in cloud". It would be very useful to have the possibility of setting them in as "locally" by default.
we are not gettting 'Sink marks estimate' results in "3D - overmolding / 2 shot molding analysis"
I am not sure, whether it is available in 2014.
Moldflow should introduce 'Sink marks estimate' results in "3D - overmolding / 2 shot molding analysis"
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
