Finite Element software for thermomechanical modeling of additive manufacturing.
Netfabb Simulation runs on the novel Pan Solver. The solver, developed by Pan Computing LLC, is based on 25 years of research and development in the fields of welding and additive manufacturing. Netfabb Simulation uses a Multi-Scale modeling approach to predict the thermomechanical response of AM parts during the manufacturing process. Simulations run in times equal to a small fraction of the time required for manufacturing on a desktop work-station. The approach is fully predictive, and does not require any calibration of the model to experimental data.
*Build volume approximately 240 mm x 200 mm x 60 mm. CPU runtime is 2 hours on a 14 core machine.
The figure above illustrates the concept of multi-scale modeling.
- The first step is to simulate a detailed Fine-Scale moving-source model to create a process parameters (.prm) file. The inputs into the prm model are the machine parameters and material properties. The output is a prm file which contains information about how a particular material will thermally and mechanically respond to a specific machine parameter setting.
- Next, a Part-Level model is run. Results from the prm model are mapped onto the CAD geometry to simulate the thermal and mechanical response of the full build.
