<strong>12.0</strong> <strong>Release</strong> <strong>Notes</strong> - Performance<br />

Parallelized Solutions<br />

The nonlinear solution can be run in parallel while performing a nonlinear response optimization.<br />

Efficient Approximations<br />

Efficient approximations have been implemented for large scale size optimization type of problems,<br />

i.e. problems with many design variables and many stress type responses. This is applicable for static<br />

problems and enables running large models in much shorter times and with much less memory. Stress<br />

and strain responses for shells, composites and 1D elements are supported. Efficient approximations<br />

can be used through the DOPTPRM,APPROX,REDUCED data.<br />

<strong>12.0</strong> <strong>Release</strong> <strong>Notes</strong> - General Enhancements<br />

Support for Unsupported BLOCK Data in the BULK Data Input Format Solution for Nonlinear Response<br />

Optimization<br />

The ASSIGN command has been enhanced to support two new file types; viz.; Starter and Engine<br />

file types, for nonlinear analysis based on Bulk data input run via the nonlinear geometry solution.<br />

These files are specified using ASSIGN,STARTER and ASSIGN,ENGINE control card options. Simple<br />

modifications are allowed in the internally generated Block data file, using the content in these files<br />

through INSERT and REPLACE. This is useful for advanced nonlinear response optimization studies.<br />

New ANALYSIS Option on the DESVARG Card<br />

This allows an optimization to be started with the design variable properties being initialized based on<br />

the corresponding analysis properties.<br />

Sequential Quadratic Programming (SQP) Algorithm<br />

Sequential quadratic programming (SQP) has been made available in version <strong>12.0</strong>. This is an<br />

alternative primal method typically used for size and shape optimization types of problems. SQP can be<br />

activated by using the DOPTPRM,OPTMETH,SQP data.<br />

DGRID (VARTYPE# on DRESP2 Card)<br />

Grid location in a DRESP2 function is now based on the local coordinate system by default. DGRIDB<br />

can be used to specify grid location in the basic coordinate system.
