Mold DYNAMIC – subscription

from: 169,00 every 3 months and a 21,00 sign-up fee


Software for 2D/3D dynamic calculation of thermal bridges (ISO 13786 – validated ISO 10211) and mold & condensation risk assessment according ISO 13788

An active internet connection is required to work with our software subscriptions. Please see our Terms of Subscription.


Mold DYNAMIC can perform 2D/3D transient fem simulations with time-variable input parameters. You can assign to the boundaries time-based curves of temperature, humidity and heat flux (for example, the solar radiation on a wall or the heat flow in a radiant system). Curves can be created with the tools of the program or imported from tabular data, such as climate data files.
Mold DYNAMIC performs a series of finite element analysis of the structure using successive points on the curves of the boundary conditions and taking into account the results of previous simulations. In this way you can obtain the actual trend over time of the heat flow and temperature at each point of the structure.

Mold DYNAMIC automatically calculates all the dynamic characteristics of the complete structure according to EN ISO 13786 such as heat transfer matrix Z, phase shift, attenuation, heat capacity per unit area, admittance and dynamic thermal transmittance.

It is important to note that these values are detected on the actual structure under consideration and therefore it can be used also for complex building components, including thermal bridges, not only for packets of homogeneous layers as normally considered.

Please note that the dynamic thermal analysis (fem) made by Mold Dynamic does not take into account absorption or migration of the steam in materials. Mold Dynamic does not perform any evaluation of hygroscopic effects according with EN 15026.

LOCAL to be installed on single computers

Mold Dynamic has been developed according to the following norms:

  • EN ISO 13786 “Thermal performance of building components – Dynamic thermal characteristics – Calculation methos”.
  • EN ISO 10211 “Thermal bridges in building construction – Heat flows and surface temperatures – Detailed calculation”.
  • EN ISO 6946 “Building components and building elements – Thermal resistance and thermal transmittance – Calculation method” For building structures the norm is EN ISO 10211.
  • EN ISO 13788 “Hygrothermal performance of building components and building elements”.

When ordering our software you can choose between two activation methods:


Option A:  activation with SOFTWARE KEY

(this is the standard activation mode, included in the software price)
You will receive via email an Activation Code that works only on the computer for which you provided an ID in the activation process.

Once the license is activated on a computer, you can always transfer it on another hardware. Using a procedure via internet, you can deactivate the license on the current machine and activate it on another computer.

To reinstall the software on the same hardware just repeat the initial procedure, inserting the same software activation key.

In the case the hard drive has been formatted or all or part of the hardware has changed, we will send you an emergency software activation key. This is possible only once and we therefore recommend to transfer the emergency key on a purchased USB dongle.

Option B: activation with USB DONGLE

This an optional activation mode: you shall buy USB dongle separately. Pick the dongle from the Catalog and add to the basket before checking out.

You can order the USB dongle also at later time: we will transfer your software key to the dongle before shipping.
Hardware Key USB Dartwin
If you choose this mode, you will receive a USB dongle that contains the activation keys for all the purchased licenses. Just enter the secret PIN code that will be emailed you separately and you can use the software on any computer simply by moving the dongle from one computer to another.

USB HARDWARE KEY with software already activated with a Software Key
Simulator Software start checking if a hardware key is available and if a valid licence code is in the kwy. If the USB key is not found or the license is not valid, program looks for a software activation key in the computer.
If a program was originally activated with a SOFTWARE key, it is necessary to deactivate the software key before using the HARDWARE key. This will be done through the transfer-license procedure, available in the help menu.
User can continue to operate with the software key until the USB key is delivered to him. When he receives the USB key he will contact Dartwin to obtain the PIN code for the hardware key.

Adding or editing the USB HARDWARE KEY
Any additions or updates of the license contained in the USB key will be carried out through a dedicated software. It is not necessary to return the key to Dartwin.

In case of problems with USB HARDWARE KEY
Our USB HARDWARE KEYS are of top quality and reported problems are extremely rare. In case you experience any problem with the key please contact Dartwin for the substitution. Return of the faulty key will be at Customer’s charge.

In case of loss of your USB HARDWARE KEY
We strongly recommend that you keep a carefully control of your USB Hardware Key. Your USB Hardware Key, together with its PIN, allows anyone to use your software in any computer. In case your Key is lost or it is stolen, you will loose also the software license associated with the Key and you will have to buy new software licenses.

Quarterly subscription
Activation with software key for single computer or on a USB stick sold separately.
The program resides and runs entirely on your computer. An internet connection is required to operate it, as the program checks every now online that activation is valid. Internet bandwidth is not an issue, because the data exchanged with our servers are only few bytes required for the verification of the presence of the activation key.

Subscription fee:  depending on the software, to be charged every three months from subscription activation.
Amount for initial activation or reactivation of an expired subscription: € 21

Credit card / Paypal (automatic payment)
By Bank transfer (manual payment)

Advanced payment for each quarter.
The subscription is automatically renewed at the end of each quarter for the following quarter, unless canceled by the user before the deadline.
The subscription is deemed to expire automatically in the event of late payment renewal of more than 10 days.

The user can decide at any time to purchase the program. In this case the license fee paid will be deducted.
The cost will be the difference between the list price plus 5% and the total amount paid for the subscription rates.
The costs of activation/reactivation and amounts paid for assistance or other service fees will not be deducted.

Example of redemption after 9 months of Mold PRO subscription:
3 quarterly subscriptions paid: 3 X €99 = €297
increase 5% = €39.5

cost of redemption of Mold PRO 3 license after 9 months subscritpion: €790 + €39.5 – €297 = €532

Excluded Amounts

Following amounts will not be considered in case of redemption:
– Amounts paid for previous expired subscriptions (non-consecutive quarters).
– Activation/reactivation fees
– Amounts paid for plugins, support, or other reasons.
