The XT2S/XT3S solver control parameters are specified in the name.iB file:
IP 1 0 2 0 0 1 1 RP 5*0 PIVOT PENAL
PIVOT is the minimum allowed pivot value during matrix factorization. The default value is $10^{-6}$.
PENAL is the penalty function value for connector elements of all types. The default value is $10^6$.
Neither the assignment /R TIMX STEP TSC/ nor the AV set is used in the AS batch.
Each load case corresponds to a single record containing a steady-state temperature field in both the name.TEM and name.STR files.
