Hi. I'm trying to take some data and apply it as a surface load. The data itself has a series of values collected over 2 seconds, at 2 millisecond intervals. The columns are like this: * X potision * Y position * Data collected at 0.002 seconds * Data collected at 0.004 seconds * Etc.
From my understanding the 'position in file' input is the column number the data is selected from. Since I have two input arguments (because X and Y), a position of 1 should take the column data at 0.002s, with position 2 being 0.004s and so on.
So what I'm trying to do is have that position vary based on the time of the time-dependent solver, which it being rounded to the nearest whole number. However doing so keeps giving me an error that the position isn't a positive integer value.
Is there no way to variate the file position with respect to that time solver? I am aware I can make the time value into a 3rd column and use 3 arguments, however the table would be extensively large. Plus, it was not given to me in that format and I don't want to put that punishment of reformatting the dataset on myself or someone else if i can make this work.
