Valve application: FSI coupling of OpenFOAM® and CalculiX
Modelling of filter applications
Already in the development, the inflow on the filter can be optimised without building a prototype. This leads to a
Your benefits from filter modelling
Modelling approach
The utilised modelling is based on the so-
Two approaches are available:
For the work with the filter solver, the user can choose between two options:
Modelling for filter applications
Modelling for filter applications is made especially easy for the user:
Support and adaptations included
A support and adaptation package is always included in the package for the filter solver. By this, we adapt the solving possibilities of the tools to your specific requirements. If you need, for example, a special form of loading characteristic for your filters, it will be provided by us immediately. We also support you with the usage of the solver.
DHCAE Tools has created a tool that enables the solving of static fluid structure applications directy from a modelling environment. CalculiX (open source) as well as Abaqus can be used as structure solver, in case Abaqus is available in your company.
The solver is suitable for solid fields and shell elements.
It uses an iterative coupling with a consistent transfer of the pressure forces and shear stresses on the structure. The shifted geometry, as simulated by the structure solver, is transferred back to OpenFOAM®. Here, a geometry update takes place, and the flow forces are transferred from the deformed geometries on the structure solver. This procedure is continued as long as a convergence between the flow forces and the shifted structure is achieved.
By the data conversion from CalculiX results to ParaView, which was made available by DHCAE Tools, the results of flow and structure can be shown simultaneously.

A test environment is available for you
For a test of the filter simulation, a comfortable test environment with examples is available for you via the Internet. Here, you can directly test your filter application and evaluate, which hardware resources will be required by you later.
