RecurDyn – Multiple contact by script

Through the normal user interface of Recurdyn, it’s very easy to create and set-up  contact between 2 bodies, A and B, taking a couple of minutes, changing the default parameters and some properties. What if  were necessary to add the interaction with a third body C? No problem, it would take two minutes for the contact between C and A, and another two for the one between C and B.

Bodies=3 Contacts=3


Ten bodies? It would be 45 contacts, it’s a long and boring job but it can be done. Ok, what if someone asked you to set up a simulation with 50 bodies interacting with each other? If each body can come into contact with all the others, we would have to set 1225 contacts (summation for n from 2 to 50 of n-1) which, counting 2 minutes each, would amount to 40 hours and 51 minutes, a whole work week  without counting mistakes, pauses and the almost certain nervous breakdown.


Bodies=10 Contacts=45
Bodies=50 Contacts=1225


We imagined this situation applied to the simulation of a handful of  “Tonda Gentile del Piemonte” ( a variety of hazelnut tha grown here in Piedmont)  that passes through a hopper and a vibrating plate to divide them according to the size.


So here is the video of the “Hazelnut paradise” project, in the coming weeks we will introduce you to the characteristics of our interface and the RecurDyn tools we used.

RecurDyn – CakeMachine

Starting from the production line data that can be modified by the operator and the profile of the decoration to apply on the surface of the cake, the tool automatically interfaces with RecurDyn, creating the model with the input data.

The software manage independently the analysis of the model and the results are post-processed,  saving both graphs of interest for the variables initially identified and the characteristic values ​​of each variable on a spreadsheet.

CAE Conference – Vicenza

On 28 and 29 October we were guests of the Pointwise stand at the CAE Conference in Vicenza, having the opportunity talk about CFD simulation, with a very experienced audience that show interested in a software dedicated to the meshing of fluid domains.

Take a look at the event page and keep up to date, we are waiting for you in 2020!
