The OptiStruct Example Guide is a collection of solved examples for various solution sequences and optimization types and provides
you with examples of the real-world applications and capabilities of OptiStruct.
MacNeal-Harder Test This is a twisted cantilever beam solved with solid and shell elements. A model is made with each element's type
to investigate the effect of distorted elements with a high aspect ratio.
MacNeal-Harder Test This is a curved cantilever beam solved with solid and shell elements. A model is made with each element's type to
investigate the effect of distorted elements with a high aspect ratio.
MacNeal-Harder Test This is a straight cantilever beam solved with solid and shell elements. Three models (rectangular, parallelogram,
trapezoidal) are made with each element's type to investigate the effect of distorted elements with a high
aspect ratio.
MacNeal-Harder Test The Scordelis-Lo Roof is a classical benchmark problem for shell elements. Analytical and experimental investigations
were initially performed by Scordelis and Lo.
Raasch ChallengeThe Raasch challenge is a curved strip hook problem with a tip in-plane shear load, posed in 1990 by Ingo Raasch
of BMW in Germany. The problem poses a significant challenge to shell elements because of the inherent coupling
between three modes of deformation: bending, extension, and twist. OptiStruct is benchmarked against the Raasch challenge to assure its shell elements performance on Linear Static Analysis.
MacNeal-Harder TestThe patch test is a classical benchmark problem for the element. If it produces correct results for the test, the
result for any problem solved with the element will converge toward the correct solution. The intended purpose
of the proposed problem set is to ascertain the accuracy of finite element in various applications.
