The simulation core of QForm runs independently from the interface, which gives incredible flexibility in how the program can be networked and in how the user interacts with the program through the powerful and flexible graphical interface. Even while the simulation is still running, the user can play the results forward and backward, make crosscuts and measurements, create graphs, and almost any other kind of analysis. The data structure can efficiently write and retrieve a huge amount of data, which permits storage of every step of the simulation results, which means that the playback is smooth and the graphic results are extremely accurate and nearly indistinguishable from the actual forging.

storage of every step of the simulation results, which eans that the playback is smooth and the graphic results are extremely accurate and nearly indi tinguishable from the actual fo ging. This data structure also means that a lot of analysis can be done in the post-processor, so users can test different scenarios without having to -r n the simulation. A simple, effective stress calculation in the die in the post-processor can show if any areas of the die are approaching or exceeding the yield stress of the die material.
