Converse at a Glance
CONVERSE is an easy-to-use software that bridges the gap between injection molding simulation and mechanical simulation. The software is used in preprocessing. The multiscale modeling approach enables to consider the complex material behavior of plastics with only a minor additional effort. A mapping of anisotropic part properties like fiber orientation, weld lines and residual stresses as well as a mapping of scalars like pressures, temperatures, wall thicknesses and shrinkage + warpage is possible. As input the software needs the results of an injection molding simulation, the model data of the structural simulation and some basic material properties. Interfaces are provided for various solvers.
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.

What Users say
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.
The coupling of fill studies and FE analysis makes the predicted results more reliable. A detailed knowledge of the plastic material properties is important to design the products closer to the limits.
With CONVERSE it is possible to use the anisotropic material behavior resulted from fiber orientation. Identifying of manufacturing process induced weak points becomes possible and a more realistic behavior of the part can be predicted.
When we were looking for software that would help us to prepare our models for the simulation of glass fiber reinforced plastic parts, we saw that the Altair Partner Alliance offers CONVERSE, which is meeting our needs perfectly.
