- The Flexible Solution for MultiBody Simulation -


1. General Introduction

1.1 What is RecurDyn-on-Demand?
RecurDyn-on-Demand (RoD) offers companies, universities, research centers, students and private households the possibility to use RecurDyn/Professional and certain toolkits just by purchasing a RecurDyn contingent for a fixed amount of money. After purchasing such a contingent, the user can start immediately to use RecurDyn whenever it is needed in order to build up models, to run simulations, to start various parameter studies, create results in order to figure out if the designed mechanism /machine works correctly.
RecurDyn-on-Demand is of interest for people who just once in a while like to use a multi-body-simulation software without investing a high amount of money.
1.2 Who can use RecurDyn-on-Demand?
  • Companies
  • Universities / Research Centers
  • Students / Private Households
1.3 In which countries RecurDyn-on-Demand can be used?
RoD can be used all over Europe.
1.4 What are the reasons to use RecurDyn-on-Demand?
  • Multibody simulation is just needed once in a while
  • High investments are avoided
  • Benchmarks can easily be done in order to figure out if RecurDyn meets the user’s demands
  • Existing CAD models can easily be exported to RoD, put into motion and analyzed
  • In order to use a multi-body-simulation-tool for a bachelor or master thesis
1.5 What offers RecurDyn-on-Demand?
  • Flexibility:
RoD can be used, when it is really needed.
  • Reliability:
All models/data stay always locally on your machine/server and behind your firewall. The used time is synchronized to the FunctionBay server system. Even if the internet gets disconnected, the user is able to use the model he worked on, but can not run simulations or switch to another toolkit. Furthermore, the user is not able to save the model. The installation of RecurDyn-on-Demand occurs on your local machine.
  • Cost Effectness:
You get what you pay – not less, not more, since the billing is 100% accurate. The used simulation time will be automatically counted and displayed.
1.6 Which type of toolkits are included in RecurDyn-on-Demand?
  • RecurDyn/Professional (Modeler & Solver), base license
  • RecurDyn/FullFlex (inc. Automesher)
  • RecurDyn/ReducedFlex
  • RecurDyn/Belt
  • RecurDyn/Chain
  • RecurDyn/Gear
  • RecurDyn/Spring
  • RecurDyn/Bearing

1.7 What kind of technical support offers RecurDyn-on-Demand?
RecurDyn-on-Demand includes technical support from FunctionBay GmbH by a ticketing system (3.1). Futhermore, a Premium Technical Support (3.2) can be booked for an additional amount, which includes support/hotline by phone, webinar and email p.a..
1.8 What kind of technical limitations underlies RecurDyn-on-Demand?
RoD licenses and modules offer the same functionalities as the RecurDyn Stand-Alone version, here are no technical restrictions. RoD is currently based on RecurDyn V8R5. Please be so kind to note that models created in RoD can be transferred into the Stand-Alone RecurDyn version and toolkits, but NOT vice-versa.
1.9 How to start RecurDyn-on-Demand:
In order to start the use of RecurDyn-on-Demand first of all the user has to register and fill in the mask. For companies it is very important to add the VAT #. Then one contingent out of three - in addition to the starter fee – has to be chosen. As soon as the official order has been sent to FunctionBay GmbH (a predefined order form can be downloaded), or the contingent has been directly paid by using Paypal, the RecurDyn software can be downloaded, a key will be generated and send to the user by email. After accepting the terms and conditions during the installation, the user can start to work with RecurDyn-on-Demand. An invoice will automaticall be created and send to the user by email.

2. General information concerning Prices & Products, Terms of Payment

2.1 Starter Fee / Reactivation-Fee and Maintenance:
In order to start with RecurDyn-on-Demand a starter fee of €300,00 has to be ordered, which includes one year of maintenance (see maintenance). Also including a starter contingent of €200,00. The starter fee is calculated separately and cannot be charged with a contingent, or a remaining credit. The starter fee concerns:
  • New users
  • Additional locations
  • Transfer of RoD to another computer
  • The reactivation of maintenance.
2.2 Contingents:
The chosen contingent enables the user to start to work with RecurDyn and toolkits. The use of RoD will be accurately charged per minute and debited from the ordered contingent. There are three different contingents available:
  • €1.000,00,
  • €2.500,00
  • €5.000,00
The contingent is limited to a duration of 24 months, including 12 months of maintenance. After 12 months the user can either decide to reactivate maintenance by ordering again the starter fee (reactivation-fee) or by purchasing a new contingent. Both possibilities include 12 months of maintenance.
2.3 Falling below a Contingent:
It is the user’s own responsibility to check the amount of the contingent frequently and to order a new contingent in time and long enough before its full consumption. In case that your RoD contingent shows a negative balance, an automatic warning will be displayed. In order to finish your simulations tasks, a new contingent should be ordered immediately. In case, that FunctionBay GmbH does not receive a new order, and the user tries to safe results of the still running simulation, those will be lost as soon the button “cancel” pushed. Of course, all other simulations and models will be frozen and can be restarted as soon as the contingent is renewed. The user can decide to receive automatically an email with a warning when a certain amount of the ordered contingent is consumed.
