The default Factor of Safety (FOS) plot would show the distribution of values over the entire model with a colour chart. Typically you would modify the colour chart to have the Minimum value as your required FOS. The regions in red are the areas of concern. However depending on the range of the colour chart values, the red colour may be appear on are regions that satisfy the FOS requirement. As you can see in the example below, the red regions could be interpreted as anywhere from 0 to 10. Yet the factor of safety requirement is 3.5.
When working with results plots in SolidWorks Simulation, the plot settings are stored under three groups, “Edit Definition”, “Settings” and “Chart Options”. After using SolidWorks Simulation for a considerable amount of time, I still forget what goes under what and I have to cycle through all the options before finding what I am looking for. Not anymore, in SolidWorks 2014, although you will still see all the three menu items when you right-click on a results plot, all three options are available as tabs in the same PropertyManager, so you can cycle through all the settings just by clicking on the appropriate tab.
The Color Chart is also “alive” now. You can double-click it and right-click it to get to various options like changing the results quantity, the min/max on the color chart, turning on/off the min/max annotations and some other settings. These are some of the enhancements to the User-Interface in SolidWorks 2014. See the attached video to see the new user interface and stay tuned for more enhancements in SolidWorks/Simulation 2014.
A limitation in SolidWorks Simulation has been that only one configuration could be active at one time. So even though there was a “compare results” tool in SolidWorks 2013, it only allowed you to compare results across studies which were based on the same configuration.
In SolidWorks 2014, this limit no longer exists. With the Compare Results tool, you can now compare up to four result plots across studies which can belong to any configuration of the model. This lets you really evaluate the performance of the variations of your design.
To access this PropertyManager, click Compare Results (Simulation CommandManager).
Under Options, select All studies in all configurations (slower) to compare up to four result plots from studies associated with different configurations.
For plots of the same type, you can select the plot which controls the settings.

Watching Alin’s blog post on Replace Sketch Entity got me thinking about how well SolidWorks CAD and SolidWorks Simulation communicate, as far as design changes are concerned. Would the replace sketch entity propagate without any glitch in existing SolidWorks Simulation studies?
I ran a simple case study just to see what was going to happen and prepared to be disappointed by the results. As much as Alin was excited about the implication of this new tool in SolidWorks CAD, I was not so optimistic.
After the first test, I literally jumped from my seat to call Alin to show him what had just happened. The Replace Sketch Entity was able to update my simulation study setup without any effort on my part!
The only way you can appreciate this new feature is to see it in action.
We have all used symmetry to boost our simulation times, whether it be planar or cyclic and were happy to have achieved the results in a short time, only to be told by the manager to run the simulation for the full model so it makes more sense to him and to the customers.
Here is a new feature in SolidWorks 2014 which will keep both you and your boss happy. You now have the option to apply the symmetry for the analysis and the software will mirror the results for you and show you the results in the entire model. These new results will actually serve as a double check for the symmetry assumptions that made.
In the PropertyManager of the desired result quantity, under Advanced Options, select Display symmetric results.
Here is a quick look at this feature in action.
Imagine receiving an assembly from a customer with a few hundred bolt connectors in it. You have to run a simulation on this. Obviously you have to suppress all the bolts in the assembly or exclude the bolts in the simulation study. And then, you need to define all the bolt connector and if you were lucky, some of the holes were actually defined using hole series which would have helped you speed up the process a little bit.
Here is the new feature in SolidWorks 2014 which will literally save you time and frustration of all this. Just create a new study in SolidWorks Simulation 2014. Right click the Connectors folder in the study PropertyManager and select:
Convert Toolbox fasteners to bolt connectors (may take time).
That’s right, just in one click, all the toolbox bolts will be converted to bolt connectors and the all the parts will be automatically unsuppressed. How is that for a great reason to upgrade to SolidWorks 2014 as soon as it is released?
Watch the attached video to see this great tool in action.
Note: This feature is available in SolidWorks Simulation Professional or higher.
A couple of days since the Public Preview release of SolidWorks 2014, I am already thrilled with all the enhancements in this new release. When 2013 was released, I could hardly contain my excitement with all the new features that were introduced in SolidWorks Simulation and now we have more new features added to SolidWorks Simulation 2014.
Over the course of the coming few weeks I will be taking you through the various enhancements in SolidWorks Simulation 2014 and how to make use of these enhancements to be more productive. For now I will go through a list of my favorite enhancements in SolidWorks Simulation 2014.
One of the best enhancements in Flow Simulation 2013 is the ability to compare results from various projects. This new feature allows users to compare results plots, goals, point/surface/volume parameters.
The comparison can be presented both numerically and graphically, so users could make decisions on most effective design modifications. To access this feature, Right Click on the Results folder in the Flow Simulation analysis tree and click Compare.

In SolidWorks 2013, now you can define sensors which can store transient data from thermal simulations, drop tests, non-linear simulations and dynamics simulation. Due to nature of simulations which support transient data, this new sensor is supported in SolidWorks Simulation Professional and above. The transient sensor replaces the existing response plots which were previously used. Loading of a transient sensor is much faster than response plots since the data is pre-loaded into the sensor.
Reaction moments are only applicable to element with nodes having degrees of freedom in rotation. This is not the case for solids as they only have 3 degrees of freedom per node (3 translations, but no rotation). So how can we get reaction moments on fixed faces of Solid Bodies?
