Optimization of simple linear and advanced nonlinear problems using TOSCA and ABAQUS
“The world is non-linear.” This statement is familiar to all ABAQUS users. In their daily work
there are a lot of problems which are not to be only analyzed, but should be improved or optimized.
This demands the availability of an optimization system which can handle not only simple linear but
also advanced non-linear problems. The optimization system TOSCA with interfaces to industry
standard solvers like ABAQUS offers the capability to treat linear and non-linear problems in an
optimization. Topology and shape optimization of ABAQUS models with an arbitrary number of
load cases and boundary conditions can be performed with TOSCA. A parameterization of the
model is not needed, which reduces the modeling effort and allows greater flexibility in the
optimized structure. Most features of ABAQUS like contact, non-linear material and special
