Product Description

CONVERSE is an easy-to-use software that provides a coupling between Cadmould® and solvers for mechanical simulation. A mapping of anisotropic part properties like fiber orientations, degree of orientations, weld lines and residual stresses as well as a mapping of scalars like pressures, temperatures, heat transfer coefficients wall thicknesses and shrinkage + warpage is possible.

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. The mapping of shrinkage, warpage and residual stresses makes it possible to conduct structural analyses with the actual part geometry opposed to the ideal CAD geometry.
