CONVERSE at a glance
Version 3.3.1 is available now
 
News in Version 3.3.1:
• XML-Export from Fiber orientations
• Interface to FLUENT (now with NASTRAN long and short format)
• Work-around toMARC for PATRAN users

CONVERSE is an easy-to-use software that provides a coupling between FEM solvers for injection molding simulation as well as CFD and solvers for machanical simulation. A mapping of anisotropic part properties like fiber orientations, degree of orientations and residual stresses as well as a mapping of scalars like pressures, temperatures, heat transfer coefficients and wall thicknesses is possible. The only pre-requisite is that both FE-models are defined in the same coordinate system.

CONVERSE enables the consideration of the anisotropic mechanical behavior of injection molded short-fiber-reinforced plastics parts in FE analysis. Hence part stiffness as well as failure can be predicted more accurate. Conventional isotropic approaches do not consider the influences of fiber orientations. With the pressure mapping capability an assessment of mold deformations, e.g. core shifts, and also of the mechanical stresses within inserts during the filling phase can be made. The temperature mapping capability provides the possibility to consider the thermal loading of temperature-sensible inserts. The mapping of residual stresses makes it possible to consider initial stress states induced by processing within the strength assessment of the part.

New in V 3.3:
·         interface to RADIOSS(bulk)/NASTRAN
·         interface to FLUENT for mapping of temperatures and heat transfer coefficients
·         mapping of temperatures, pressures and residual stresses now also for ANSYS
·         mapping of wall thicknesses for shell models from CADMOULD to ABAQUS
·         graphical evaluation of mapping quality

"For the simulation of short-fiber-reinforced plastics parts we use CONVERSE consequently. Due to that we are able to improve the quality of our simulations significantly. This helps us to design our parts considerably better."
