  1. Hi, problem is, i want to automate the process. Meaning that i want to save the trimming operation of the curve in a session. By relaoding this session, the trimming should automatically happen for a new curve (which i read in with the same session), where the y=0-point of this new curve can slightly differ from the previous curve. So, if one used the suggestion in your last post: When reloading the session with a new curve, the trimming operation would not hit the right x-value because the y=0 abscissa value has changed. But the x-value of the trimming should change according to the new curve. Could you provide another solution?
  2. Hi George, as i wrote, that option (it's what i meant by "trim function" ) doesn't work for me because the right hand trimming point is not variable, but is fixed to a certain x-value. I want the x-value to vary, accordingly to the value y = 0
  3. Hi, im looking for a function to trim a curve. The goal is to create a new curve in a different plot, that represents only a portion of the original curve vectors. Further goal is to keep the right hand trimming point variable, meaning that i want to trim the curve on the right hand side not at a fixed x-value, but by meeting the criterion: "trim at location where the y-value becomes zero" (occurs only once in every curve). This should also account for the case i reload the session containing the trim operation, but with varying curve values. Left hand trimming point may be a fixed x-value. I already tried: 1) the trim function: problem is, that right hand trimming point is not variable -> not workable 2) macro Cut below limit: problem is, that after the limit, the newly created curve is extended by a horizontal line -> not workable Is there a function like this?

  4. Hi G. P. Johnson, are there some new insights to this ? Regards, Florian
  5. Hi, i tried the following: 1. i loaded my template with the predefined formats 2. i opened advanced options in build plots menu, it shows different formats than the formats i defined in the template. 3. when i load a curve from binout, the resetting of formats is done again. THAT'S WHAT I DO NOT WANT! the advanced options are no use to me if i still have to redefine the formats everytime i load a curve...
  6. Hi, sorry, but where can i find the advanced plot option menu? i found "advanced build plots" under "Misc*" menu, but can't open it because tehre is some tcl missing:
  7. Hi, i am using report templates for HG with predefined text formats for axis titles, header, etc. When opening the blank template, everything appears as it should. However, when i load a binout history plot (from LS-DYNA) into one of the HG windows, the format of the labels is reset and i have to reformat them. Is there a solution to prevent the formats from resetting??
  8. Hi all, i am missing some reference on the taperd-T-seam-connector in HM (LS-Dyna profile) in the help documentation. there are three types with different parameter sets but i need some description of how they influence the elements geometry. Could you help ? ?
  9. Hi, in the meantime, did you succeed with a morphing sample case? I am at a point were this might be useful again..
  10. If i had used translate i wouldn't have asked about this option. No of section should be 9 Is morphing really an option? How does it work in this case?
  11. Hi All, i have some components distributed on a certain distance and want to redistribute them over a new (slightly longer) distance, please see attached picture. How do i do that? Scale wouldn't work, because the dimensions of the parts would be scaled too.. Thanks for any help!
  12. Hi, There are 7 base units in SI, of which 3 are commonly used in structural Analysis: Time, length and mass First step is to choose a unit for each of these three quantities (could be s, m, kg) The units for all other quantities are derived from that choice, because any other unit (except the 4 "non-structural" base units) is a composition of time, length and/or mass. In Josh's example: For 1N=kg*m/s^2, you have to check if the right side units are the same as your chosen base units. If every single one is the same, then your force unit is correct with 1N. If not, you have to put in the right orders of magnitude to achieve that your chosen units appear on the right side of the equation. So if you have chosen mm for length, this unit is not consistent with the length unit used in the equation and you have to put in 1000 on the right hand side to replace m with mm. Then divide the equation by 1000, to eliminate the number from the right hand side. On the left you get N/1000 which equals 1mN. So for a set of base units like s, mm, kg, your force unit will be 1 mN.
  13. Hi, You can look up the TIE Keyword in the Optistruct Helpfile. What exactly do you mean by "Large/small pattern", are there differences in the element size?
  14. So, you are using SHELL-Elements for both, Carbon and HC? Could u send a Picture were one can see the mesh of the carbon? I think you are using a pretty coarse mesh for the HC. You should use the that type of Connection which best fits your desired output, depending on the desired detail, so to say. For instance, if your not interested in failure or deflectional behaviour of a bonding layer (or whatever), then i would choose a tied contact (in optistruct available via PCONT- or TIED-Keywords. TIE works well, i recently figured).
