Top 5 Highlights of Simufact Welding 2020

Direct Energy Deposition (DED) – New Module for Simufact Welding

With the release of Simufact Welding 2020 users will now be able to simulate Direct Energy Deposition processes (DED). This new module inside Simufact Welding 2020 helps the user quickly and efficiently setup robust DED models in order to calculate and evaluate for stress, strain, distortion, thermal history, and hot spots during manufacturing and post processing.

The DED models utilize common robot programming such as the G-Code which allows the user to simply import existing tool paths instead of defining weld paths manually.

G-Code Import for Welding Processes

With the latest release of Simufact Welding 2020, the users are enabled to work with common robot code such as the G-Code. With this function, the software can easily process complex welding sequences that were difficult to implement manually.

Many types of G-Codes can be processed automatically and translated into welding trajectories inside the model. Also, it will be possible to identify and automatically process velocities as well as welding source status, if available. These data can be used for definition of weld paths and heat source properties.

Pre-Processing improvements by implementing, among others, Leblond Model and scripting

One of the most important highlights of the latest version is the implementation of the Le

blond phase transformation model which is implemented in the solver and Material GUI. The implementation allows processing of CCT data and converts it into model parameters. This allows user-defined transformation kinetics for steels.

Another highlight is the newly implemented scripting functionality based on Python that helps to script and automatize recurring activities. This is a great benefit if regularly several variants of a model are to be set up with e.g. different welding sequences or clamping conditions. The focus lies on automatically processing changes in existing models eliminating the need to manually use the GUI for it. Thus, they will save enormous time.

Additionally, Simufact Welding 2020 offers enhancements for middle and large-sized models by improving the performance of the 3D view as well as the general GUI performance. As a consequence, it makes model setup significantly faster and streamlines the workflow.

Enhancements in the post-processing such as MPCCI-Mapper or filter options

An interface was added to exchange simulation results to and from the MpCCI-Mapper, which in turn can be used to transfer properties like deformations and stresses from third party products into the welding simulation and vice versa. This allows to exchange data with Abaqus, LS-Dyna and several other products.

Another feature of the latest version is the enhanced evaluation functionality of the results. The user is now able to filter different results which allows a more qualified evaluation of the process with respect to the simulation results. The filter is also able to extract or highlight selected elements or nodes in the 3D representation of the model. During model debugging and understanding, it helps to detect several critical situations that might have occurred during the calculation process. Furthermore, a new convergence monitor helps to track the solving performance of the model and to identify possible improvements in terms of calculation time and result quality.

Calculate resistance spot welding process quickly with several robots

Simplified approaches enable users to calculate large resistance welding processes with several robots welding at the same time. Take advantage of Simufact Welding 2020 to quickly achieve needed results in terms of distortions, stresses and temperature fields.

Additionally, the possibility to use the thermal cycle approach for more than two sheets inside the weld spot is added. This provides more flexibility to the simplified modelling approach and avoids the need to use the transient solution with higher computational effort if more than two sheets are involved
