  1. Hello, I’ve the task to build a ply-based solid composite model. The tricky part is, I have to build the model out of plies, which are drawn in Catia Shape Design (see picture 1). Why do I want to model each layer as a solid (ply-based solid composite model)? First reason, the composite part is used in a load introduction area. From the literature, a solid design is recommended. Second reason, I want to make use of Altair MultiScale Designer (MSD). In Optistruct only solid elements are currently supported with user materials. Therefore I use MAT9ORT as material. In the last step I replace the material information with an user defined material (woven 5 harness satin), which I get from the MultiScale Designer (MSD). Why is the composite part drawn in Catia Shape Design? Since the design of the composite part is complex at many points, Catia Composite Design (CPD) couldn’t be used for that. Instead the whole composite part is drawn in Catia Shape Design. Each layer (=ply) is drawn individually. So the geometrical informations I get from the CAD model are correct. But I have to work with this model and cannot rebuild it in CPD. What I've tried so far: I loaded each layer into Hypermesh and meshed the components (automesh, quads only). Then I created the materials (MAT9ORT), the plies (PLY01, ...), a laminat stacking and properties. Last I would do a shell to solid conversion. (see picture 2) Problems and questions: The layers don’t know each other. So the mesh of each layer is different. (see picture 3) Moreover in the thickness direction of the plies, they are not really connected. (see picture 3) Can you help me to find a strategy to build up the laminate out of the shapes I have from Catia? Since I’m an unexperianced HM user, I kindly ask you to explain your help and instructions in detail. Thanks a lot! My software: Hypermesh 2017.2 OptiStruct as Solver Multiscale Desinger 3.4 for the user material Catia V5
  2. Hello Everyone, Currently we have designed a Tank (Thin surface - Topography Optimization) in CATIA V5 and want to optimize it. Is there any method that will facilitate automatic changes in the model without requiring to make changes manually in CATIA V5 after Optimization. A part of my Project is to investigate a method that will automate design optimization with CATIA V5. In the Altair Website I have found a method (http://de.slideshare.net/AltairHTC/s15-hs-zwickau) but not sure on how to apply it. Any further sugestion would be really helpful. Thank you in advance
  3. Hey guys I'm new to solidThinking Evolve and I need help about dimensioning my drawings. Can we give dimensions to our sketches like in CATIA or solidworks? Also, can we edit position of points according to dimensions? What are dynamic and static dimensions in evolve and how are they different? Please help. Thank you in advance☺️
  4. Hello guys, I need your help in this context. CATIA "imagine and shape" and solidThinking Evolve are these same? Are both used for class A surfacing? What are relative advantages and limitations of these two softwares? Thank you in advance
  5. Hello Everyone, I just started using Hyperworks with some examples and found out that SimLab allows to Import CATIA design parameters and publications along with geometry. But Unfortunately I get an error saying IMPORT Failed. Could anyone provide the possible reasons for this error?? Also one more question is if I can perform DOE with the CATIA design Parameters in Hyperworks through SimLab?? Thank you in advance
