Load Control file
Load Control files are ASCII and must have a .lcs extension. Format, explanation of each input, and a typical file are shown below.
<Description>
<Units>
<Number of load cases>
<Number of FE cases>
<Divisor 1>,...,<Divisor m>
<ID1>, <Desc1>, < scale 1>,..., <scale m>
...
<IDn>, <Descn>, <scale 1>,..., <scale m>
The number of FE cases has to be greater than or equal to 2. Blank lines after the 5 header lines are ignored, as is anything after the # character. The ID must be a positive integer. The divisor values are the scale factors (as divisors) for normalizing the stresses and must not be zero.
