  • thanks guys - that has given me some great ideas. I've started playing with the variation of density with temperatures. I see that temperature allows a location dependency, so I vary this with a function based on hgt (z). I then apply a custom step…

  • understood -thanks again for a quick reply
    in Temp issue when used with contacts Comment by Fatmac February 28
  • thanks for the rapid -reply. I have been looking at a model with a core laminated structure and was seeing differences when I used shell and solid laminates in CCX in buckling situations -i think it may partly due to the way I have "fixed" the end f…

  • i've been using pretension sections as shroud adjusters in yacht rigging models -its a bit of a work up and I imagine it sucks up some computation time but it has appears to work and sort of self aligns also.

  • Thanks again - it is all slowly becoming a little clearer!
    in Plastic deformation Comment by Fatmac February 16
  • Its pretty clear I need to go back to school where it comes to the definitions of all the different types of stresses and strains!. My focus was more to see how the different types of plastic models work and compare against each other. Also to see …

  • thanks again for all ur insight -I will take another look now I have more info about all the different types of strains there are!

  • I 4got to add that sometimes u get better structured meshes (certianly in gmesh) if u partition the piece into 3 and 4 sided sections - slice them in ur CAD program and re-join them b4 exporting. then try these gmesh comands then i get something …
    in Structured mesh Comment by Fatmac February 3
  • within MW u can use customised comands for gmsh - paste the following into the "custom Gmesh commands" in meshing parameters and u will get a reasonable 2d mesh Mesh.Algorithm = 11; Mesh.ElementOrder = 2; Mesh.RecombinationAlgorithm = 3; Mesh.Reco…

  • Rhino has a great function called quadremesh -for 2d meshes like this it works nicely

  • thank you disla for looking at this - i had a little play with this and managed to get more sense out of it by swapping the contact surfaces as u suggested. I'm afraid some of the other suggestions u made were beyond my level of understanding. "Proj…
