Stores data in the database for the defined variables.
Lab
Valid labels:
MERGE
—
Merge data from results file for the time points in memory with the existing data using current specifications (default).
NEW
—
Store a new set of data, replacing any previously stored data with current result file specifications and deleting any previously-calculated variables (see Table 2.88: Operations).
Variables defined using the ANSOL command are also deleted if they represent element-based results. Variables created using nodal-averaged results are not deleted.
APPEN
—
Append data from results file to the existing data.
ALLOC
—
Allocate (and zero) space for
NPTS
data points.PSD
—
Create a new set of frequency points for PSD calculations (replacing any previously stored data and erasing any previously calculated data).
NPTS
The number of time points (or frequency points) for storage (used only with
Lab
= ALLOC or PSD). The value may be input when using POST26 with data supplied from other than a results file. This value is automatically determined from the results file data with the NEW, APPEN, and MERGE options. For the PSD option,NPTS
determines the resolution of the frequency vector (valid numbers are between 1 and 10, defaults to 5).--
Unused field.
FREQ
A frequency value, or an array containing frequency values (Hz). Use *DIM to define the array and enclose the array name in percent signs (for example, STORE,,,,%
arrayname
%). A default value of 1% of damping is considered for clustering around the user-input frequency values. Supported forLab
= PSD only.Toler
Tolerance to determine if a user-input frequency value (
FREQ
) is a duplicate and can be ignored. Two frequency values are considered duplicates if their difference is smaller than the frequency range multiplied by the tolerance. The default value is 10-5. Supported forLab
= PSD andCluster
= YES only.Cluster
Key to control whether or not to consider the clustering frequencies around each of the user-input array values. Available only when a user-defined frequency array is used (
FREQ
).YES
—
Merge the clustering frequencies around both the natural frequencies and the frequency values entered in the user-defined array (
FREQ
) (default).NO
—
Do not include clustering frequencies, and use only natural frequencies and the frequencies in the user-defined array (
FREQ
).
Command Default
Merge newly-defined variables with previously stored variables for the time points stored in memory using the current specifications. If STORE is preceded by TIMERANGE or NSTORE, the default is STORE,NEW.
Notes
This command stores data from the results file in the database for the defined variables (ANSOL, NSOL, ESOL, SOLU, JSOL) per specification (AVPRIN, FORCE, LAYERP26, SHELL). See Storing the Variable in the Basic Analysis Guide for more information.
The STORE,PSD command creates a new frequency vector (variable 1) for response PSD calculations (RPSD). This command should first be issued before defining variables (NSOL, ESOL, RFORCE) for which response PSD's are to be calculated.
If the frequencies in the user-defined array are relevant, turning off
clustering (Cluster
= NO) reduces calculation costs without
significant loss of accuracy. You can check the frequencies by initially issuing a default
RPSD (with clustering) to obtain a reference plot of the response.
