  1. Depending on the WINDOWS version, the graphic engine and the screen, the graphical display of the software can be optimized by the following individual options (even applys for other software): 1. Display scaling factor (WINDOWS display settings) set to 100% 2. Compatibility set to the used WINDOWS version (right click on software > settings) 3. Set “Overwrite high dpi scaling behavior. Scaling performed by Application” (right click on software > settings)
  2. Challenge Detect weak areas due to weld lines Estimate the influence on the part strength Solution Converse mapping capabilities in order to assign weld line areas and flow angle to the mechanical model Results Optimized manufacturing process Knowledge of local varying component strength
  3. Yes, of course that is possible. Shape and mesh don´t have to be the same. Thank you for your question.
  4. Size matters! At least when it comes down to the finite element size. To cover different layers of fiber orientation in a fiber reinforced material it is necessary to use a fine mesh, but to keep the cpu time low, it has to be as coarse as possible. I´d like to share with you the following experience: - Midplane meshes of course are the best opportunity to caver as much information over the thickness as possible since it is simply your choice how many layers you´d like to use. - A Hexahedral mesh is nice to keep dof low, but can only cover as many information as there are elements over the thickness. - Tetrahedral meshes usually take less time in preprosessing and are usually the best choice to represent complex geometries. For short fiber reinforced materials they have another benefit. The center of each Tet-element is slighty shifted over the thickness and therefore, covers different information. In this picture you see the fiber orientation distribution function over the thickness (legend) and an example micrograph showing this effect in a real part. The different mesh types have different pros and cons when used to take these effects into account:
  5. Challenge Realistic material behavior of injection molded fiber-reinforced plastics Reduce weight by metal replacement Solution Converse mapping capabilities to assign fiber orientation to the mechanical model Converse material database for direction dependent thermo-mechanical material properties Results More realistic simulation of parts compared to isotropic approaches Consideration of injection molding process on the mechanical part behavior
  6. Saving Material Without Performance Loss Challenge Reducing the weight without loss of usability and strength Optimizing the manufacturing process Solution Injection molding simulation to optimize the part production and to create the fiber orientation for the new designed part Taking into account these results to perform most realistic mechanical simulation Results Significant material and cost savings due to optimized geometry Faster and more economic production process
  7. Please feel free to share your CONVERSE experience with us! Here are some users statements: 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. Dr. Matthias Teschner, Director Engineering / Validation MANN+HUMMEL GmbH, Ludwigsburg, Germany 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. Tamás Schmidt, Engine Development Department Audi Hungaria Motor Kft., Györ, Hungary 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. Christian Bresser, Senior Manager Process Mechanics Mechanical Simulation Huf Hülsbeck & Fürst GmbH & Co. KG, Velbert, Germany 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. Nicolas Pluy, Mechanical Simulation Expert Valeo Lighting Systems, Wuhan China
  8. What is the difference between CONVERSE Basic and CONVERSE Advanced? With CONVERSE Basic all mapping features of CONVERSE are already available, but the material model is limited to anisotropic linear-elastic material properties. A more advanced material model for non-linear behavior is only available in CONVERSE Advanced only. Does CONVERSE need to run during my simulation? No. After the mapping is done and the required files are exported Converse can be closed and the simulation can be started with these files included in your original file. Is a User-Subroutine required for an analysis using CONVERSE data? Since CONVERSE only uses existing solver commands of the supported solvers there is no User-Subroutine required. This is more stable and faster due to unlimited usage of parallel computation. Does the Converse Database provide ready to use Materials? How many? What materials? Are they solver dependent? CONVERSE offers dozens of materials in the database and of course they can be used, but please make sure to test the material first. Therefore we recommend to perform a simple tensile test simulation and compare the results with your datasheet to avoid unexpected results. What injection molding software products can I use with CONVERSE? CADMOULD, MOLDFLOW, SIGMA (SIGMALink), MOLDEX 3D, SIMPOE, 3D TIMON What mechanical solvers are supported by CONVERSE? CONVERSE provides interfaces for the following mechanical simulation solvers: RADIOSS, ABAQUS, ANSYS, OPTISTRUCT, NASTRAN, MARC, LS-DYNA and SAMCEF as well as to the following fatigue analyzer: FEMFAT, NCODE, LMS Virtual.Lab What are the main mapping features of CONVERSE? A mapping of the following properties is possible: Anisotropic fiber orientation, degree of orientation and material properties as well as weld lines and shrinkage & warpage. Also transient pressure and temperature values can be assigned. Beside these main features there is even more available. Please have a look on our website for further details: http://www.partengineering.com/software/converse/ What is the CONVERSE batch option for? The batch option allows to proceed several steps automatically in CONVERSE. The user defines the number of steps to be executed. The whole procedure until the export of the mapped information can be done or for example just the import and mapping process to display the mapped situation in CONVERSE again. Do my models have to be defined in the exact same position? What if structural and injection molding models are defined in different coordinate systems? It is not required. A coordinate transformation option is available for re-position of the source part. Can I use several different injection molding results (components) with one structural model (e.g. welded housing)? Yes, you can open and close one by one and assign the properties. It just has to be made sure that the target has at least as many element sets or part definitions as you have source components. My solver/feature is not supported by CONVERSE. Will it be available in future? The work of our developer team is always depending on our customers wishes. So please feel free to tell us what comes to your mind at converse@partengineering.com
