SIMUFACT ENGINEERING released Simufact.forming 13, a new version of its metal-forming process design and optimization software, noting it provides improvements in post processing, evaluation and the depiction of the simulation results. It also promised more precise results, better software stability, and improved simulation process speed.
Among the new functions available to Simufact.forming subscribers, the developer listed “user-defined result values”: user-friendly mathematical formulas allow the user to generate his or her own result values based on those of the simulation. “In many cases,
this new function renders the programming of subroutines completely unnecessary,” it explained. “Users can define their own color schemes for the depiction of result quantities and therefore can evaluate simulation results according to their own criteria. This function simplifies the post processing process when examining the variables in the design process
Also new is a “post particle tracking” function, which helps the user to find the causes of typical mistakes in a massive forming process. Post particles are user-defined measuring points for the parameters, and users can define them after the actual simulation, during post processing, and during all process steps while running the simulation forward and backward. If a simulation indicates an imperfection, such as a fold formation, under-filling or overfilling of the die, the user can define the measuring points during post processing.
Simufact.forming 13 introduces an expanded status display for remote synchronizing (i.e., the transfer of the simulation results to the local client.) This function is useful for client-server installations where calculations are done on a network rather than on the client, according to the developer.
Another new function is shared-memory parallelization (SMP), which Simufact claimed will reduce computation times by up to 50% when simulating with the FE-solver, or 10-15% using the FV solver, by implementing additional parallelization to the assembly of the stiffness matrix.
The automatic definition of symmetry planes saves the time and effort of defining the planes manually, and the time and effort needed to adjust the press force and its maximum force.
In addition, simulation results now can be exported from Simufact.forming 13 in the I-DEAS Universal format, e.g. for a subsequent structure simulation.
Last, for users who apply Simufact.forming to simulate mechanical joining processes, the geometrical properties of hollow self-pierce riveting processes are determined automatically and visualized. This helps users to evaluate the highly realistic results of the simulation quickly.
