Example of continuation of analysis using dynain.lsda and *CASE
A sequence of load steps is set up as a sequence of analyses
================================================================================
L_bracket_dynain.key        Main run file for *CASE and dynain.lsda approach
run_pretens.key             Load case definition for the pre-tensioning
run_xload.key               Load case definition for the X-loading
run_yload.key               Load case definition for the Y-loading

L_bracket_allin1.key        All-in-one analysis for reference, all loadings
                             vary with time

bolts_nodel.key             Nodes and elements of the geometry 
bolts_partsec.key           Remaining keywords of the geometry: Parts, sections
                             sets, etc.

case1.dynain.lsda           Dummy dynain.lsda file, sometimes required to get the
                             analysis started
case2.dynain.lsda           Dummy dynain.lsda file, sometimes required to get the
                             analysis started
