QForm
QForm is further development of QForm simulation software that has got many new features and modules.
Models and methods:
- Ring rolling model as a dedicated feature of the program that is based on new computational methods and has a specialised interface.
- Dual mesh method that is now available for different kinds of processes including rolling, cogging etc.
- Client-server and cloud modes of program operation
- Extrusion simulation module
- Heat treatment simulation module aplicable for steels and aluminium alloys
- Microstructure evolution module
- Advanced facilities for simulating with elastic-visco-plastic material model including load controlled tools and rotating billet like in flow forming
- Cold forming, spring-back and residual stress calculattion
- Task planer and batch mode
- Advanced parallelisation of calculations that increases the simulation speed
Moreover, the program has many new features in the interface, source data preparation and simulation control, data import-export, interaction with the third party software and advanced results output.
New development brings more benefits to industrial, research and educational implementation of our software.

Main features
New interface and architecture
The revolutionary new architecture allows the simulation core to run independently from the interface. This makes the graphical interface extremely powerful and flexible. Even while the simulation is still running the user can play the results forward and backward, make crosscuts, measurements and any other kind of analysis. The new data structure efficiently writes and retrieves huge amounts of data, which permits storage of every step of the simulation results. This means that the playback is smooth at 25 frames/second and the results are extremely accurate and nearly indistinguishable from the actual forging.
Reliability
This also means that a lot of analysis can be done in the post-processor so you can test different scenarios without having to re-run the simulation. Even for forgings when the surface collapses creating severe laps, the simulation runs to completion and the results are very accurate. With QForm you can accurately trace tracked points and flow lines forward and backward, produce graphs and numerical data from tracked points, modify the fit of inserts or shrink rings in tool simulations, and calculate user defined functions all in just in few seconds from the post processor. The sophisticated mesh generation algorithms can easily handle formation of laps and folds, intensive shearing deformation, multiple bodies like bimetallic billets or composites as well as pre-stressed die assemblies.
Advanced features
For advanced users, QForm allows easy programming and seamless display of User Defined Variables and Functions. Any kind of model like flow stress data, ductile fracture, or microstructure evolution can be added to the program easily with user-defined functions and anyone who has ever tried to do this on other software platforms will appreciate that no compiler is required and these functions are performed at the same speed as the main code. Moreover, to make programmingin QForm even easier it also includes built-in code debugger.
Flexibility
QForm is well suited for hot forging shops, cold formers, fastener manufacturers, and extrusion plants that are looking to improve quality while reducing scrap and the costs of tooling. It is also ideal tool for education and research due to its flexibility and user-friendliness.
