DOPTPRM, TMINPLY

Bulk Data Entry Defines the minimum ply thickness allowed for all plies of PCOMPs selected by DSIZE or DTPL design variable definitions.

Definitions

Parameter Values Description
TMINPLY 0.0 ≤ Real ≤ min(Ti) Should be smaller than the minimum of all relevant Ti on the selected PCOMPs. Check its compatibility with volume constraint if applied.
Note: For volume fraction calculation, TMINPLY is not treated as none design volume in the same way as T0 for regular PSHELLs.

Buckling responses for composite structures may be considered for free-size and topology optimization when this parameter is non-zero.
