ANSYS Parametric Design Language (APDL) is a powerful structured scripting language used to interact with the ANSYS Mechanical solver. Mechanical APDL (MAPDL), a finite element analysis program, is driven by APDL. APDL and MAPDL can be used for many tasks, ranging…
Submodeling Technique from Beam to Shell
Submodeling, as the name suggests, is the modeling of a portion of a global model to capture the effects of refined mesh in a smaller model. This is done to avoid having the whole assembly meshed with fine elements. ANSYS Mechanical…
Structural Optimization Analysis with ANSYS DISCOVERY
The term structural optimization is commonly used for the optimization of engineering structures for improved strength or stiffness properties and reduced weight or cost.ANSYS Discovery 2022R1 provides topology optimization with the following options: Optimization for Strength or Response to Free Vibration….
Structural Optimization Analysis
How to get clean CAD Geometries and Optimized Design CheckingThe new topologies that are obtained in a topology optimization simulation cannot be used directly. They must be transformed in CAD geometries. We present below how to reverse engineering the optimized component…

High Frequency Simulation and Verification Course
Introduction In the autumn of 2019 we started a High Frequency Simulation and Verification Course using ANSYS products at the Faculty of Electronics, Bucharest. It consisted of 3 hours laboratory sessions taking place every 2 weeks. The course reunited undergraduate, master…
Cavity resonances in two dimensions
Introduction This article is the final one from a pair of three, each characterizing a different frequency interval in the impedance profile of two parallel power planes. I investigated the capacitive interval in thisolder article, the inductance in a blog post…
Spreading inductance in wide cavities
Introduction In this article I direct my attention toward the study of inductance. The reason why this measure is important to be studied is the same as previously mentioned with regard to capacitance, which I have in depth investigated in a…
Parallel plate capacitance approximation and limitations caused by the fringing effect
Introduction This article was started a long time ago and while investigating its topic of interest I stumbled upon a different subject which quickly materialized in this interesting study. The present article initiates a small series of posts dedicated to investigating…
Frequency-Domain characterization of FR-4 dielectric using Djordjevic-Sarkar algorithm
Introduction I must admit that this topic was not on the list of future blog posts and is something I stumbled upon while investigating the limitation of the parallel-plate approximation formula for the capacitance of two planes separated by a dielectric…
