  1. Hi there, I'm trying to connect my composite models together between blue component and black component by using area connector -> hemming,. However, i modelled the thin red layer between those two components for adhesive definition (the reason why i do not use adhesive connector from thr first place is due to mesh size neccessity since the thickness of adhesive layer is relatively thin compared to other components while i would like to control the mesh size if adhesive component). My approach was that in area panel choosing hemming type connector where is the location of elements is upper-red layer connecting to blue component and lower-red layer connecting to black component. The connector failed to realise which i do not know why, please advise. Thank you.
  2. Hello there! At the moment i am modelling composite structure using solid elements (has to be solid elements only in my case), would like to know how could i define material orientation to my laminate layers, for example 0/60degree. There is some limitation on my model, since my model is in circular shape (please find the attachment) which means i need to define cylindrical co-ordinate system. I could not define material orientation directly by changing CORDM to be user and then add coordinate system in particular direction of angled ply as i used to do with rectangular plate (since i need to define 2 co-ordinate systems: cylindrical + 60 degree material orientation). I have tried with PCOMPLS-solid-shell approach but seems like not working in my case as i am performing thermal analysis using temperature card. Can someone suggest me how could i model this component in the way that 1. I need to model using solid elements only 2. There are 4 layers of plies -> 0/60/60/0
  3. Hello, has anybody ever got this error before? -> OptiStruct ERROR: 1 the full message is OptiStruct ERROR: 1. A fatal error has occurred in your model. Please refer to the .out file to obtain more information on how to correct it.

However, everything was working just fine until today that i am trying to modify the model configuration and start running the analysis again then this error popped up. Please help.
  4. Have you found the answer? becaus i have the same problems i would like to add +-60degree of material orientation to solid element. The difficulty is that my component is in round shape which requires a cylindrical co-ordinate system as well.
