  Hi Dave,

  It looks like your table file isn't defined correctly. You have 404 x co-ordinates and 380 y co-ordinates. This means you should have 152737 grid elements but you only have 75978 defined. Here is a pdf that should help you with how the table file should be set up.

  Best Regards,

  Chloe

  Hi Chloe
  
  I managed to sort out the grid issue. When I am plotting my material, there only seems to be half my data being plotted.  I am not sure if I need to define a new material axis.
  
  The xcrd from my flxtbl file goes from 0.001 upto 0.01105 (data1) then 0.001 upto 0.01105 (data2)

  
  What I am aiming to do is take  data1, horizontally flip the material and join tem together like a mirror image. I believe this is done now correctly in Matlab and needs something altered in the script. The flxtbl file should contain all the correct information now.
  
  If you have any ideas that I could try or if you could have a look at the updated file. I would greatly appreciate this.
  
  Thanks
  
  Dave :)

  Hi Dave,

   

  Could you send a link to the updated files please. The previous link still has the old ones.

  Thanks!

  Hi Chloe
  
  I eventually figured out how to solve this issue and have this up and running. So thank you for the document you sent me, it steered me where I had to go and ironed out other issues.
  
  If I may though, I have one last question about a line of coding in my script. In Lines 72 where I read in my rotations file,

  c Materials
  symb #get { nmat } tablmatr $tfname
  axis
  symb #read Rotations_50um.txt
  form angl
  defn matAx1 cart 0. 0. 0. 0. 45. 0.
  end

  The line that reads

  defn matAx1 cart 0. 0. 0. 0. 45. 0.

  I am unsure exactly what is happening here.
  
  From what I can see it is defining the material axis for each material in my rotational file and giving it the name called matAx1. Am I correct saying that the 6 proceeding integers represent (x y z i j k)?

  0. 0. 0. 0. 45. 0.

  What exactly does this 45. represent and what is it doing to my data and how does it affect my simulation.
  
  Thanks
  
  Dave :)

  Hi Dave,

  defn matAx1 cart 0. 0. 0. 0. 45. 0.

  The above command is defining a local co-ordinate system which allows you to orientate the materials it is applied to. Have a look at the Command Reference for more details on the syntax (available in Help tab of OnScale). But basically the 6 proceeding integers are the x y and z global co-ordinates of the origin of the desired local system co-ordinate and the three rotation angles about the global axes that will transform a global system into the desired local system. 

  I hope this helps!

  Best Regards,

  Chloe
