Multi-start Optimization in ILIAD – Part 2: Through the Eyes of the Algorithm
Last week we discussed the concept of multi-start optimization and a simple and effective ILIAD workflow for implementing a multi-start optimization to find the global maximum of a surface. This week we will use ILIAD’s toolkit to look deeper into the strengths and...
Multi-start Optimization in ILIAD – Part 1: The Nested Workflow Approach
By seeking maximum improvement with each iteration, gradient-based optimization algorithms almost always offer design improvement faster than their non-gradient-based (genetic algorithms, simulated annealing, particle swarm, etc.) counterparts for continuous design...
Accounting for Uncertainty in Optimization
Optimization is typically applied to deterministic problems, i.e., a problem in which all variables have an exact value and that can be calculated using fixed mathematical formulas. However, in real life, it is almost impossible to measure the exact values due to...
Engineers, Assemble!
Design Studio for Genesis® makes it easy to organize your model by letting you create collections of groups/properties called assemblies. Assemblies are non-exclusive – that is, groups may be included in more than one assembly. There are a number of built-in assemblies, such as all PSHELL or all PSOLID or all sizing-designed groups.
Topology Design of a Compliant Mechanism
Genesis® for Ansys® Mechanical (GSAM/GTAM) adds the power and versatility of Genesis® structural optimization capability to the ANSYS environment. Engineers can enlist the rich breadth of Genesis® optimizations, performing optimization data definition, solving, and post-processing all within the Ansys analysis systems. In this article, we would like to show how to perform topology optimization to design a compliant mechanism.
Frequency Response Optimization – Total Control
Introduction Frequency response optimization capabilities in the GENESIS software allow its users to improve practically any type of results that come from structural frequency response analysis. Examples of responses that come from structural frequency response...
Custom External Analyses and ILIAD
The modern engineering design process commonly involves numerous commercial and in-house analysis programs. In order to accommodate custom codes and software without dedicated interfaces, ILIAD offers the Executable and File I/O components, which allow users to add...
Integrating Matlab and Simulink Models inside ILIAD Workflows
In previous articles, you have seen how Iliad captures all the different components of a design process onto a single digital platform. In this week’s article, we look at how easy it is to integrate the different scripts and analysis inside Iliad workflows using our...
Enhance Model Reports with Tags
Design Studio for Genesis® makes it easy to save pictures of the model shown in the viewport. This is particularly convenient to report design optimization results shown in post-processing. Design Studio also has the capability to add tags (also known as...
Topology Optimization for Thermal with Dynamically Updated Convection Boundary Condition
Genesis® for Ansys® Mechanical (GSAM/GTAM) adds the power and versatility of Genesis® structural optimization capability to the ANSYS environment. Engineers can enlist the rich breadth of Genesis® optimizations, performing optimization data definition, solving, and...
