Grid Point Strain Output Request
Description: Requests grid point strain output.
Format:
Example:
GPSTRAIN = ALL
| Option | Definition | Type | Default |
|---|---|---|---|
| Grid point strains will be output to both the Model Results Output File and the results neutral file system. | Character | ✓ | |
| PLOT | Grid point strains will be output only to the results neutral file system. | Character | |
| PUNCH | Grid point strains will be output additionally to the Model Results Punch File. | Character | |
| SHEAR | Maximum shear stress request for shell elements and octahedral shear stress request for solid elements. | Character | |
| VONMISES | Von Mises stress request for shell and solid elements. | Character | ✓ |
| REAL or IMAG | Requests complex output in rectangular format (real and imaginary). | Character | ✓ |
| PHASE | Requests complex output in polar format (magnitude and phase). Phase output is in degrees. | Character | |
| PSDF | Power spectral density function, RMS, and number of positive crossings output request. | Character | |
| ATOC | Autocorrelation function output request. | Character | |
| RALL | Both PSDF and ATOC will be output. | Character | |
| THERMAL | Thermal strain request for shell and solid elements. | Character | |
| MECH | Mechanical strain request for shell and solid elements. | Character | |
| TOTAL | Total strain (thermal plus mechanical) request for shell and solid elements. | Character | ✓ |
| ALL | Grid point strains for all elements will be output. | Character | |
| n | Set identification of previously appearing SET command. Only strains for grid points whose identification numbers appear on this SET command will be output. | Integer > 0 | |
| NONE | Grid point strains will not be output. | Character | ✓ |
Remarks:
- Only grid points connected to elements used to define the surface or volume are output. (See the SURFACE and VOLUME commands in Section 3, Case Control.)
- See the STRAIN command in Section 3, Case Control, for the equations used to calculate strain invariants.
- If the MECHSTRAIN model parameter is set to ON (default is OFF), mechanical strain will be output regardless of settings on this command. (See Section 5, Parameters, for more information on MECHSTRAIN.)
