The mixing process is an integral component of the process industry, with a wide range of applications utilized to create tailored products that meet the diverse needs of various industries and customers.
Computational Fluid Dynamics (CFD) simulation products are for engineers who needs to make better and faster decisions and can help reducing the development time and efforts while improving your product’s performance and safety.
Materials information is crucial in engineering and manufacturing as it enables informed decisions. In simulation and modeling, precise materials data is needed to accurately predict real-world behaviour.
Since day one, our customers have been at the centre of our focus. Whether we’re taking care of our existing users or onboarding new customers into our yearly care cycle – quite simply – nothing is more important to us than you, our customer.
At EDRMedeso you learn from some of the industries top experts in their respective fields. With over 1500 collective years of experience in simulation, we provide a host of training sessions to suit your organizations needs
EDRMedeso Productivity Tools – short historical review & 2022R2 update
On October 5th EDRMedeso held an update webinar about the productivity tools for Ansys Mechanical. Read the story about the people behind the apps, how EDRMedeso helps to solve customer pains and how you can contribute.
The Mechanical productivity tools or “apps” are some of the products from the Technology and Innovation group managed by Frode Halvorsen (CTO) at EDRMedeso. In the team we also find Fredrika Dahlberg (Innovation Manager) and Magnus Gustafsson (Senior Application Manager and Developer) who has driven the app initiative at EDRMedeso for many years.
It all started back in 2016 when Ansys opened for third party licensed apps with the release of Ansys R17 and the creation of Ansys Appstore where you could find and download the apps. We (EDRMedeso) had experimented with some small free and paid apps for some time, but this new solution opened new possibilities that we embraced, says Frode.
The aim of the Technology and Innovation group is to help our customers by adding new products or vendors to our portfolio that bring value to our customers, Fredrika says. When we work with innovation at EDRMedeso we start with customer needs and develop a product or onboard a vendor that best solve this need. The apps are a great example of such project – Magnus found that something was missing and realized that more than him had a need for certain features and started the project. Today that project has turned into a great product with partners around the world!
And the customers’ feedback is still in focus, Fredrika continues. It is exactly one year since the re-launch of the apps and during this period we have received a lot of feedback from our customers. Valuable input that has been the guiding star for the latest updates, or “APPdates” that we have started to call them.
We have summarized the latest appdates below, if you want to see the webinar you find the recording here. At the bottom of this article, you also find a link to our app home page where you can read more about the apps and use the contact form if you have any questions or feedback to us.
What our customers are saying about the apps
During 2021, EDRMedeso sent out a survey among the users to ask for their feedback on using the apps. The result was encouraging to read as it is a confirmation that we are on the right track providing solutions to the common simulation pains such as “Time to market” and “Human errors” when dealing with complex bolted and welded assemblies that includes code assessment.
What our customers wants to have in the apps
In the same survey in 2021 we also asked the customers if there are missing features or enhancements they liked to see. We put this list to the backlog for the continuous development of the apps and started working on it.
In the following section we present the “You asked for it, we implemented it” summary!
“-A combination of weld fatigue and weld strength toolkits…”
Weld Toolkit is the new common tool for weld strength and fatigue introduced in 2021.
“-More fatigue data would be nice.”
Stress-life curves for aluminum according to Eurocode 9 is added in Weld Toolkit 2022.
User defined S-N curves may be added in the app and saved in the preference file as well.
“-…descriptions how to use the existing tools…”
New step by step engineering tutorials for weld strength and fatigue is included with the Weld Toolkit app in 2022. Similar tutorials are also planned for Bolt Toolkit.
“-Bolt toolkit utilization considers only shear force in bolt (not frictional surface). Eurocode3 does however not allow for exclusion of these forces.”
With the recent version of Bolt Toolkit released in 2021 the full Eurocode 3 assessment is now implemented with the different joint categories and all criteria for bolt normal and shear force as well as contact slip and more.
Bolt fatigue according to Eurocode 3 is implemented in Bolt Toolkit 2022R2 and cumulative damage is coming in 2023R1.
“-I hope that the most recent release of Bolt Toolkit Extension will allow a better postprocessing.”
The post-processing in Bolt Toolkit 2021 was re-made to allow for more result entities in the bolt and contact zones as well as an open API to define user defined criteria.
“-Individual numbering of the items, simple inclusion of only the tabular data of all types of results.”
The post-processing now displays bolt/weld id numbers in the GUI and the automatic report provides easy to read property and result summary tables.
“-Structural stress fatigue of welds.”
Any weld strength result may be used as input for a “structural stress fatigue” result.
The stress type may be an individual stress component, or the “equivalent” stress defined in the weld strength result based on the selected weld code.
“-Use the hot-spot method in combination with add fillet welds.”
Welds created with the “Add fillet weld” can easily be post processed with the hot-spot fatigue method so that the correct offset is defined by the weld throat size.
“-Currently it is quite clunky and time consuming to interpret the results of the notch method. … What this causes is a singularity on the cut boundary constraint, and this then pollutes the edges of the notch solution to show extremely low life.” “Applying the notch method to curved welds.”
The notch fatigue method is improved to use the longitudinal edge along the notch to display the result from the notch. It is also possible to automatically exclude results from (cut) boundary constraints. Other improvements are to use general curved faces and to select stress type (tangential/principal/equivalent) to use.
“-Solution combination of different analyses systems”
The solution combination feature in bolt and weld fatigue will be updated in 2023 to allow selecting result steps from any analysis system in the model tree in addition to the “Current Analysis”.
