(Assembly environment – Simulation module)
When there are many parts in a study, the amount of connectors (created automatically or manually) can be overwhelming. I t is important to remain in control of those connectors as their quantity increases. Otherwise, it will be a difficult task to find the source of the problem when a fatal error occurs during solving.
A recommended method for medium size assemblies
The user of Solid Edge can include only a subset of the parts that will eventually need to be analyzed. This way, a limited amount of connectors will have to be created. The workflow is to modify the boundary conditions to accommodate this partial study (add temporary load or constraint) and solve to verify that the connectors play their role and keep the studied parts connected. Then, the user can modify the definition of the study to add more parts or start from a copy of the study to keep a backup of each step. Each following steps, necessary to build the full study, will require the addition of new connectors and modification of the boundary conditions.
A recommended method for large size assemblies (with thin walled parts)
The user of Solid Edge should use mid-surfaces (psm) or other type of surfaces when analysing thin-walled parts. In addition to this, the user has the option to connect surfaces and create one or several associated bodies for the analysis. This will remove the need for connectors as the nodes merge at the intersections. This approach needs to be considered seriously when hundreds of parts are being analyzed.
With these workflows, the Solid Edge user who wants to build a complex analysis can confidently and progressively add all the required simulation features to run a full study. The capacity to verify a subset of connectors and, afterwards, move on confidently to the next group of connectors can be a huge time saver when dealing with large assemblies.

A parametric assembly contains links that can transfer data (number, geometric references) between components so that they can share common characteristics. Such a link can be updated if the communicating components are activated and if the active context wasn’t modified since the link was created.
One way to alter the context is to use the ‘save as’ command when in the assembly environment. Solid Edge warns the user about the danger of such an operation:
Analyzing a “broken” model
If you have a parametric assembly that is unresponsive, select a part with a chain beside it and edit it. At the top of the modelling tree for that part, you will see a ‘Links’ collector. If you expand it, you will see the context (the complete path is in the tool tip as shown below) in which parametric features of that part can receive data from other components.
How to fix it with ‘Redefine links’
Open the View & Markup application (Start/Programs/Solid Edge...). In the ‘Tools’ tab of the ribbon, start the command called ‘redefine links’.
Select folder(s) in which all components of the “broken” assembly as well as the assembly itself reside. Note: for a complex assembly with many components distributed across multiple folders, it is possible to use a result log (txt file) of the V&M ‘search broken links’ command.
Enter the path including the filename to the original (old) context (the one listed in Solid Edge as shown in the previous image) and then the path to the current “broken” assembly (also with the file name).
Altering the context of a parametric model can occur in different ways. It is always recommended to use the revision manager and its ‘where used’ command when moving or copying projects or libraries in order to prevent this kind of damage. Nevertheless, mistakes happen and it is nice to have an easy tool to repair parametric links.

Designfusion is proud to be a sponsor and major contributor to this year’s New York State RUG meeting. This year’s meeting will be held at the RIT Inn & Conference Center in Rochester NY, on October 7, 2014. All users are invited, even those who live outside of New York State. Designfusion will be presenting at 8 of the 35 planned seminars. Our focus this year is Solid Edge and Teamcenter Administration, however there are plenty of other presentations for all attending, as you can see from the agenda below.
Not only is this a great learning opportunity, but it’s also a chance to meet and network with other users and some of the people who support your Siemens’ PLM software.
There is a small fee to attend this event, and you must register in advance. You can do this online at http://www.plmworld.org/new_yorkrugevent. This site will provide you with all the details of the conference and directions to RIT Inn &
Conference Center. We hope to see you there, and don’t forget to drop by the Designfusion booth in the sponsor’s area.
