  1. Hi Skill I think if they have the same energy errors, which one gives you less elements is better than the other one.
  2. Hi. I used this menu but I can not create an ellipse in 2D. Could you please show me? Tks
  3. Hi Ivan Thank you for your answer. I used the script to show the orientation of solid element. But I am still not sure whether the red axis is r axis ?
  4. Hello I am modelling one yarn with solid elements (pls see the picture). The material is orthotropic M12 and Prop 6. I don't know how to how to assign the 1 direction (longitudinal direction of the yarn) for the solid elements in this case. Could you please show me how to do? Thanks
  5. Hello With Hidden Line Plane we can obtain a cross section but we can not use this section for measurement. Could you please show me how to create a plane view (for example XY plane wher Z=10)?
  6. Hi In my opinion, we can use contact 19 for self contact
  7. Hello I am using MAT69 for my model. But I dont understand well about fct_IDblk Function which scales the bulk coefficient as a function of the relative volume. In my opinion this function allow to scale up the Bulk modulus as a function of relative volume so I created one curve with X is the relative volume and Y is the scale factor but nothing changed. Could you please explain me about this function! Thank you
  8. @IvanThank you very much. In my model I have an equivalent material with the stress and strain as the picture, this curve seems like hyper elastic material. I used Mat LAW69 and it works .I am still wondering about this kind of material because the strain is not so large (only 15% maximum)
  9. Hi. I tried to use Mat LAW36, as I know, I created a stress and strain curve and put it in fct_ID_E but It said YOUNG�S MODULUS SCALE FUNCTION SHOULD DECREASE WITH PLASTIC STRAIN ERROR ID : 975 ** ERROR IN MATERIAL FUNCTION DEFINITION How can I deal with this problem?
  10. Hello I have the stress - strain values at discrete data points from uni- tensile test. Could you please tell me 1. Which Material for this situation? 2.How too include that in Hypermesh while defining material properties ? Thank you! 
  11. Hi @Ivan My problems is when I set Igap = 1 2 or 3 I got initial penetration so I set it to 0
  12. Hi @Ivan Thank you very much I solved my problems. But I found that Iform = 2 is recommended for Implicit and low speed Impact Explicit Analysis So I think for contact type 7 we should set Iform = 1
  13. Hi I use HM 2017.2 and Abaqus 6.13-4 I have a model with 2 components in HM. I used HM/ABAQUS standard 2D. I exported my model as *.inp file but when I imported it in ABAQUS it combined 2 components into 1 part instead of 2 parts
  14. Hi I try to export a model with 2 different components with mesh, but when I import it in Abaqus they are all in one part. How can I import them as 2 different parts
  15. @evgenabaqus I have the same question! Did you get the answer?
