I'm trying to obtain the displacements of a node from an FEA .txt results file using matlab. I want to search for the node (e.g. 5151) and then read the displacements, the problem is the node is mentioned a couple of times before getting to the deformations. The part of the results I'm interested in looks like this......

                                       N O D E   O U T P U T



   THE FOLLOWING TABLE IS PRINTED FOR NODES BELONGING TO NODE SET ASSEMBLY_TIP_NODES


   NODE FOOT-   U1          U2          U3          UR1         UR2         UR3

   5110      1.8586E-03 -6.0265E-03  3.2271E-03 -7.6400E-02 -1.2011E-02 -6.7206E-03

etc, so what I want to do is search for a unique string ' N O D E O U T P U T' and then search for '5151' and import its displacements into an array.

Example output nodeDisp = 1.6791E-03 -4.3652E-03 2.4334E-03 -6.5533E-02 -8.9528E-03 -4.8933E-03

  • give an output example . – Nishant Jun 17 '14 at 13:53

    You might be better off if you pre-process the text file first to get rid of the text and headings. Then you can read the columns into an array easily. – kkuilla Jun 17 '14 at 14:03
  • Question edited to include output. Essentially I just want the displacements of the desired node saved into an array to be used later on in the data processing. – user2739143 Jun 17 '14 at 14:04
