We have developed this platform for you, our customers, based on discussions we had at conferences, business meetings, consulting projects or while having a coffee.

Until now, we focussed on building a strong credibility in the NVH industry and our customers, manufacturers and laboratory partners list confirms we are on the right path.

Now that we have implemented our new frequency domain data visualization, converted our On-Premise version into an entreprise solution and integrated automation for our customer relation interaction, we are ready to scale!!!

Help us enrich this database by registering and purchasing a subscription plan to benefit from our database globally.

How it all works

How do you want to use dBPorous?

On the web? On your internal company servers (On-Premise)? Or a mix of the two?

dBPorous offers not only the possibility to buy high quality and low cost material properties of NHV products but it also offers a framework where you can store/view/compare/edit your purchases.
Furthermore, you can include your own material properties accumulated over the years into dBPorous and make them available to your NHV simulation teams around the world.

On the Web

Process Subscribe

dBPorous on the Web follows a 3-step process: Subscribe-Shop-Download. 1) Get tokens from a subscription plan, 2) Use these tokens to buy material properties of available materials in database and store in MydB, 3) download the properties from MydB in the form of a lab report and your favorite CAE software material card. Your data is ready to be used into NVH numerical models.

Furthermore, you can import your own company material properties into your secure company section in dBPorous on the Web and make these properties available to your NHV simulation teams around the world.

On-Premise and Web

Process Subscribe

dBPorous On-Premise and Web follows a similar process as the web version, however your company data is more secure since the MydB section is directly located onto your internal company servers. This option therefore offers added data security and the ability to purchase material properties from dBPorous On the Web and importing these into your internal company server.

Furthermore, you can import your own company material properties into dBPorous On-Premise and share with your NHV simulation teams around the world through your company network.

On-Premise

Process Subscribe

dBPorous On-Premise offers the maximum security dBPorous can offer. The MydB section is installed on your internal company servers and normally do not allow your employees the ability to import data from dBPorous on the Web. However, if needed, your dBPorous On-Premise admin can import data from dBPorous on the Web as an ad-hoc solution.

Furthermore, you can import your own company material properties into dBPorous On-Premise and share all data with your NHV simulation teams around the world through your company network.
