I would like the ability to work on one design scenario while another scenario is busy doing something else.
For example, if a model is meshing in design scenario 1, or if the analysis is running in design scenario 1, I would like to be able to setup a model in design scenario 2, 3, whatever.
I know frequency vs. amplitude/magnitude plot can be plotted by using EXCEL macro (provided by Autodesk) in post-processing of a frequency response analysis. I hope that the frequency vs. amplitude/magnitude plot and phase plot (i.e. Bode Plot) are plotted in Sim-Mech Results Environment without EXCEL macros.
Any Body to Body radiation that is set up for heat transfer analysis is not shown in the tree anywhere. Surely it should be shown under 'Load and Constraint Groups'.
A feature I think would be useful for a lot of people would be to insert the possibility of selecting the the coordinate system of the FORCE regardless of the coordinate system of the element to which it is attached.
The reason for this is that:
1- You must change the edge's coordinate system in order to change the coordinate system of the edge force you apply to that edge.
2- In MES, if you have the edge in a different coordinate system, it is harder for the model to converge.
I often work with large plate structures with many overlapping parts that are welded or bolted. Using midplane mesh should be the best way to achieve this to achieve a reasonable run time/accuracy compromise. With the help of your support staff, we have explored the many ways to achieve this but have found that midplane meshing is too hard to use (see my posts or history with subscription centre).
I found that I have to resort to using 20 node brick elements often only 1 element thick to achieve a reasonable run time/accuracy compromise.
What would be very helpful is to add a way of adding contacts between midplane meshed parts just like between solid elements (i.e. bonded, welded contacts etc). Hopefully this could be done automatically or manually.
In addition, It would be great if we could add bolts to midplane meshed parts just like solid meshed parts.
Along with this, it would be wonderful to have an easy method of adding welds between midplane meshed parts.
Fatigue tool is great in many sense but the currect application is 32bit and fails to work on large models. Can we upgrade the fatigue tool to 64bit so one can work with larger models.
Alternatively, the interface can be adjusted to selectively transfer parts to fatigue tools. Currently this can be done only after whole model is read into the fatigue wizard application, which creates the bottle neck. It may be just easier to add this filter funtionality to enable working with larger models.
I often use Sim-CFD to calculate the pressure drop and velocity profile of my fluid models, and I need an easy to use method to map those pressure results to SIM-Mech so I can study the deformation and stresses in the solid parts.
I frequently model structures that have thin cross sections but are welded and oriented in ways that make plate/shell elements undesirable. It would be nice to be able to define requirements for meshing brick/tet elements such that one could have greater control over their generation.
An example of this is a welded structure of thin walled square tubing where von Mises stress is important to the design. The ability to control the meshing so that there are at least 3 elements through the thickness of the tubing but the elements are long and slender enough that there isn't too many elements would be advantageous. Additionally, this may help minimize the issue when the mesher goes into the mode where is "Closes Remaining Voids" ad infinitum.
Perhaps one way of doing this is to select two surfaces and define a minimum number of elements that must be placed in between them for standard brick/tet elements. Thoughts?
It would be nice if the rectangle selection worked similar to AutoCAD and Inventor were a left to right box only selects enclosed lines, and a right to left selection selects enclosed and crossed lines.
ABAQUS has a results feature in their 2D models that provides the contact pressure between two surfaces. This would be very useful when determining how much two surfaces are in contact (i.e. gaskets for instance). Currently Simulation only has a feature for 3D.
I would like to be able to lay out my mixed model (wireframe+solids) in Inventor and then export wireframe and solids into a single model in Autodesk Simulation Mechanical.
Today we can only import Surface and Solid parts from Inventor to Simulation Mechanical.
It would be great if we can import Wireframe geometry in addition to Solids and Surfaces directly from Inventor to Simulation Mechanical, instead of having to convert the wireframe objects to an IGES file.
My short wish list:
1) The program to be reconfigured so that when you kill a meshing session, kill an analysis the program QUICKLY,
completely terminates such that you can proceed with your changes.
2) All windows are closed at the same location ie at the lower RH of the window is where the box to click would be located.
3) A part in the model can be updated from the solid model instead of re-importing the entire model and re-establishing all the node based features that were lost.
4) The bugs that I found and were reported to the developers were actually corrected.
I am going to stop there. Thanks.
I would like to be able to export the results from a "parametric dimension" static simulation and/or be able to view my contraint values for each simulation at once, rather than having to use the little scroll bar to view the results for each individual configuration. Also, it would be nice to be able to generate cross/overlay plots for multiple constraints, ie convergence of min. weight and max safety factor.
I often analyze assemblies that has 10 or more parts. I need an easy to use postprocessing tool that can show me the minimum and maximum results for a given result type (such as von Mises Stress or Temperature) on a per part basis.
A user I was speaking with proposed that Simulation Mechanical/Multiphysics be able to display the material color when a material is chosen for a part, instead of the parts of an assembly all just being gray (unless it has been assigned to a cad model and imported with it). So, for instance - say there was an assembly that you obtain from a step file. If you assign a material of gold to one or more parts, those parts would display in a gold color... cast iron a dark gray and so on. I like the idea, it would mimic what Inventor currently does.
Submodeling is a powerful tool available in many analysis tools. Even if the model sizes can be increased with currently technology, there is still a need for submodeling capability to analyze certain areas of a design. Development team can start with extending the interpolation tool for temperature results to displacement results and such.
I would like to be able to use the groups, defined in FEA EDITOR, also for the post processing
in the same way, on a model, when some probes are defined, it could be very useful to have the same ones on a scenario (with the same mesh) created by copying the originial one (where the probe is present)
In the same time than it has been proposed in the 2014 version the keeping of the nodal joints,...it should be great to keep the loads applied on nodes, after a remeshing.
This could be easily made by defing any nodes that support a force as a construction nodes and so to be kept..
