Large assemblies in classical finite element modeling

Today, the FE modeling of complex assemblies, especially machines, is coupled with a series of key problems:

  • Plenty of time and effort spent on importing CAD models into the FE software
  • High error probability causes often comprehensive validation work
  • Extensive modification effort in case of assembly changes and variant configuration
  • Limited reuse and transfer of FE models
  • Extensive variant management of FE models

Use of standardization

Typical machines consist of up to 90% of the same components (standard components): servo drives, ball screws, linear guides, rolling bearings, clutches, gears etc. The modeling of these components is done based on macros. The rest of components (machine beds, tool slides, quills) requires a comparatively einen verh?ltnism??ig a small proportion of the modeling time.

For reasons of efficiency it makes therefore a lot of sense to work in FEM based on a component- and library-based approach, similarly to CAD.

MESHPARTS offers the optimal solution to the current problems. The unique advantages provided by our innovation you can read in the following.

A paradigm shift in the simulation

Your FE simulations become

  • 10x faster and more cost-effective
  • more accurate and performant

User-friendly and automated

Intuitive features such as drag & drop, 3D visualization as well as automated processes such as automatic detection of component interfaces allow easy assembling of FE model components to complex assemblies.

Component-oriented generation of the simulation model

Following the assembling of the simulation model, the modular intelligence (structure, position information, contacts) is retained, so that the assembly structure can be adapted any time with just a few clicks.

Parametric variation in the level of detail

Components can be generated from very simplified to very detailed. The more detailed the geometry, the more accurate the results, however the longer the computation will take.

Parametric variation in the mesh accuracy

The mesh accuracy represents the number of finite elements in proportion to the volume of the component model. The finer the mesh, the more accurate the results, however the longer the computation will take.

Specialization in FE particularities

In addition to the spatial positioning of components (similarly to the well-known positioning in CAD), MESHPARTS considers all FE relevant physical contact properties for each contact between the component models. This saves the FEM engineer a lot of work and provides him or her with a reliable basis for the simulation process.

Automated variant management

For each component, parametric model definitions are stored in the MESHPARTS library. The user has the possibility to enter his or her own parameters, which are automatically transferred to the model definition. This way, customized component variants are generated in a simple way and classified automatically in the library.

Re-use instead of repeated modeling

The MESHPARTS Library stores and administers all fully generated components. Each model can be downloaded and, using the MESHPARTS software, assembled into different FE assemblies as often as necessary.

Quick access to validated knowledge

Due to the well-ordered storage structure, the specialized search function and a naming algorithm based on property characteristics, the appropriate validated FE models are very easy to find.

Parallel co-working

The MESHPARTS library can either be integrated into the corporate network or used online, so that users can access content from anywhere. In consultation, multiple users can work separately at various subassemblies of the FE module.
