Before 2009:

Performance of CFD calculation services with Fluent, ADINA (FSI) and OpenFOAM by Dr. Ulrich Heck as a freelancer


Foundation of DHCAE Tools GmbH for software sales and focus on software development and services for OpenFOAM, whereby the simulation services provided continue to represent the entry point for many companies for later in-house use.

First software tool: CastNet GUI is launched on the market: First pre-processing tool for OpenFOAM for in-house use with meshing, CAD import and automation functionality


Participation in the EU project: CloudSME: Development of an interface to our OpenFOAM monitoring software for the use of computing resources in the cloud (e.g. AWS)


Extensive OpenFOAM extension for filtration applications to be presented at Filtech exhibition and conference


Participation in the EU project: CloudFlow: Development of a digital twin in the cloud for extrusion tools, FSI application (coupling CFD/FEM for the expansion of slot dies)


Research Project atomisation of liquid melts: Development of atomisation tool


Presentation of a comprehensive tool for atomization modeling with OpenFOAM (transition from VoF to Lagrange modeling)   


BMWK lightweight construction project: Development of an automated workflow for cooling titanium components with subsequent creep modeling


Launch of new website www.cfdtools.com with focus on automated CFD design tools
