Reducing the size of the results files (*.mys and *.out)
-
Reduce the number of load cases in
a linear analysis by splitting them over two or more Analyses.
-
Check the
mesh refinement in your model (reduce the number or
interpolation order of elements, if appropriate)
-
For nonlinear analyses: If it is not necessary to view explicitly graphical output (i.e. deformations and stresses) for every increment, you
may reduce the size of your graphical output file (*.mys) by writing to the plot file less often than every increment
as follows:
TreeView >
Analyses tab > (double click) [a nonlinear control
loadcase] > (check) Nonlinear & Transient >
under "Incremental LUSAS file output" Plot file
= 5
Entering a value of 5 (for example) will mean a plot file is written for every 5th increment. The default is 1, i.e. every increment.
There are no specific option to reduce the amount of
data written to a *.mys file. Other possibilities
include:
-
For nonlinear analyses: use restart files to stop the analysis
at various stages and then restart, creating a new results
file each time. All the results files created may be combined
together in Modeller at a later stage. There is a
pdf document which describes using restarts for a transient dynamic
analysis example on our scripts
page called Performing
Vertical Pedestrian Loading with Restart Analyses.
-
For nonlinear analyses: use the HISTORY facility and write out
specific results for a specific variables. The results stored in the time history file can be accessed for graphing.
Specification of the node and element numbers to be output to this file is defined from the
File> Export Solver datafile... menu item. The output frequency for incremental analyses is controlled using analysis
control (right-click on the Analysis in the Analyses tree view and
then click Edit in the context menu and got to the Advanced
Output Options tab).
-
To
reduce the amount of disk space required to store a
"*.out" file you can zip up or otherwise compress this text file
considerably. The "*.mys" file is a binary file
and is already compressed to an extent when created by Solver, but
it may also reduce in size if compressed, but to a lesser extent.
