# Control Cards

Control card entities create solver control cards such as results file I/O options, CPU and memory limits, and others.

/STATE/STR_FILE When writing the state file, /INISHE, /INISH3 and /INIBRI will be written in a separate file which can be asked for being compressed (using GZIP) or not. The state file will then resume to the nodes coordinates and element connectivity.
Note: Engine Keyword
/STOP The Engine is stopped, due to reached energy error ratio criteria, total mass ratio criteria or nodal mass ratio criteria.
Note: Engine Keyword
/TFILE Defines the frequency of writing the time history file of T-file "RunnameTnn".
/TH/VERS Generates the Time History files in Radioss environment post-processing format "Version Number".
