  1. Tommy, Thank you for your kind feedback.
  2. Dear all, For instance, I have a surface model of a Tube with D = 400mm and thickness = 16mm. So, the middle surface (MS) in the model lies at a diameter of 384mm. So, I've 2D mesh the middle surface and know I have created a PSHELL property to define the thickness corresponding to the tube. What thickness should I consider to represent my tube, 8 or 16mm? Thank you in advance.
  3. Ok I got it, thank you so much Q.Nguyen-Dai and tinh. But know I have another question, because I have a big structure I do not want to do all the process by hand ( that would be very time consuming) Is there a TCL scripting code to that automatically? I mean just selection all teh tubular structure at once and give me all the midlines? Thank you for your kind support.
  4. Hi tinh, Thank you for your attention to this matter. I'm not really seeing your point. I have a strucutre like this and i need to extract all midlines (in blue) in between. Could you please be more clear? Thanks
  5. Hello everyone, I'm retriving this topic again in order to see if someone could help me. I have a 3D model (tubular structure) I want to mesh with 1D CBAR elements. Anyone please know a quick way to get the midline of the 3D model tubes? Thanks in advance.
  6. Hi Ivan, Thank you so much for the very useful information. Just one more question. Is this possible to have the nodal stress values of my CBAR element in an output file? Reason for that is because I wanted to automate my process instead of post process the results manually with hyperview. Thank you.
  7. Hi Ivan, Thank you for your kind reply. I think this control card returns you a .strs output file with stresses in the elements of your 1D (CBAR) structure. What I'm looking for is the Stress on the nodes. Thanks
  8. Hi everyone, Could you please tell me how to get the maximum combined stress ( Axial +Bending) on nodes for bars in ALTAIR? What kind of control card (Global Output Request) I need to define on my pre processor to have this data. Something like this ( attached file from PATRAN)
  9. Ok I explain better. When for instance I want to read the content of a .txt file in my scripting I just type something like this: file = fopen ( ' nodes.txt'.'r'); nodes = textscan(fid, %d %f %f %f %f ) fclose(fid); Now I want to read all data from my .oml file as well. What command I need to use to open my .oml file, that's my doubt? For instance from MATLAB I know that when you need to call a (.m) file in your code you just type the name and the program automatically recognizes it. Hope this make sense.
  10. Thanks Lorenzo. It works for the file conversion. My problem now is to invoke that file (.oml) inside the scripting code. I already tried to type the name of the file on editor's window but unfortunately it doesn't work. Do you know as well how to do that? Any help would be greatly appreaciated. Thank you.
  11. Hi Lorenzo, Yes sure. It's a file combining a cell array 'Casename_Track' and a huge matrix 'Track_Stress_Matrix'. Something like this. Thank you very much for your help.
  12. Hello, Anyone knows by chance how to open and read all data in a .oml file that contains a Matrix [n;n] and a Cell array of strings ? Thank you
  13. Lorenzo, Thank you so much for the info. Do you know as well how I can edit the color, values and scale? Regards, Henrique
