Validation of SORPAS® Simulations

Many factors influence the simulation results. In order to minimize the amount of work that users have to do to verify the highly dynamically coupled numerical models and their interactions with the input conditions, we have already made a lot of verifications and validations of all models with lab tests and user feedback. Many numerical … Continue reading


How to minimize errors in simulations?

In order to minimize the risk of errors in the simulation, we recommend that you check carefully the following points to see if they are correct before pressing “Start simulation”: Geometric models and dimensions Sheet thickness Coating thickness Electrode shape / bulk diameter / tip diameter Electrode tip face curvature Material data Sheet material Coating … Continue reading


What are the requirements for my PC to run SORPAS®?

The recommended computer specifications are as follows: Type of computer:           Server computer / desktop / laptop Operation system:           Windows 7 / Windows 8 / Windows 8.1 / Windows 10 System architect              64-bit system (SORPAS® 2D runs on both 32 and 64 bit, but SORPAS® 3D runs only on 64-bit) Processor speed:              3 GHz or higher … Continue reading


Export of data

Export of data to LS-Dyna You can export your simulation results from SORPAS® 3D into LS-Dyna. Go to: “File/Export/Results to LS-Dyna Export of data to DynaWeld You can export your results from SORPAS® 2D into DynaWeld. The interface enables you to export process simulation results from SORPAS® and continue the simulation with DynaWeld. Choose “File/Export … Continue reading


Can I use an absolutely flat tip design for the electrode?

Absolute flat tip of electrode does not exist in reality. Even if they made the electrode with absolute flat tip by design, after just one weld, the tip face is deformed to have a natural curvature with a radius of R=50mm to R=100mm approximately. The ISO Standard electrode forms are mostly with tip face curvature … Continue reading


Can I add coating to a rivet?

Yes, in SORPAS® 2D. joining you also have the possibility to add a coating to the rivet like in 2D. welding. On how to add coating to the rivet follow these steps Open the file and go through edit data file. Select the rivet you want to add coating on. Under Geometry and Materials find … Continue reading


Add a new electrode to the SORPAS® database

If the electrode you want to use for the simulation is not in the library, you contact us on our support portal with specifications of the electrode from your supplier. If you are an active user of SORPAS®, we add the material free of charge. You can also add the electrode yourself, follow the instructions … Continue reading


Add a new machine to the SORPAS® database

If the machine you want to use for the simulation is not in the library, you contact us on our support portal with specifications of the machine from your supplier. You can also add the electrode yourself, follow the instructions in the manual. If you are an active user of SORPAS®, we add the machine … Continue reading


Add material to the SORPAS® database

Folders in database When you create new materials, we recommend that you first create a folder in which you place your customized materials. This makes it easier to keep track of what is standard materials and what is your customized materials. See instruction on how to create materials below. Variations of standard materials You can … Continue reading
