Altair Compose® Challenge 5: Drive Inspire using Python in Compose
Altair Compose is commonly thought of as an engineering math toolbox, a tool for handling computationally intensive operations, model complex systems in 0D, process data, etc. but Compose is an equally powerful tool when thought of as a driver of other tools’ simulations and the glue that connects all the simulations and…

Altair Inspire® Challenge #6: Lilly Pad Optimization
This challenge is to run a topology optimization on the base of the Water Lilly Pad that is supported at its centre, with water pressure loads in the vertical and horizontal directions. Note that the location of the ribs in nature is not purely based off of achieving maximum stiffness, or minimum mass, but also considers…

Altair Compose® Challenge 4: FIR Filter Design
The signal processing OML library contains more than 60 functions that you can leverage in Compose. Some of these will help you design and test both digital and analogue filters. The task for this challenge is to design and validate several types of finite impulse response (FIR) filters. Namely: * Lowpass filter with…

Altair Inspire® Challenge #5: Prosthetic Knee Motion Analysis
This challenge is to run a structural analysis on one of the components of the model, using the motion resultant forces as a Load case. Find the Prosthetic Knee project attached to this challenge. Run a Motion Analysis in the Motion Ribbon, open the Motion Run Settings in the Analyze Motion icon, select an end time of 2.0…

Altair Twin Activate® Challenge #3: Electrical domain Modelica components
Modelica is an equation-based language that is especially well-suited for modeling the behavior of physical components. Activate supports several Modelica libraries, allowing users to create physical-based models, often simpler than their signal-based counterparts. Modelica components are acausal, which means that, instead…

Altair Inspire® Challenge #4: Overcome Porosity Issues with Casting Simulation
Porosity is one of the major concerns in Casting Manufacturing. Air entrapment during filling and shrinkage porosity during solidification can compromise the quality and aesthetics of the casting product. Sometimes, it is not possible to 100% eliminate the porosity from casting. However, certain scenarios where optimizing…

Altair Compose® Challenge #3: Transfer Functions & Data Handling
In this challenge, we will focus on highlighting how Altair Compose can simulate a system’s response from its transfer function, and how data can be written into and read from CSV files. We will model a simple mass-spring-damper system: The transfer function of this system is given by: Where m is the systems mass and b and…

Altair Inspire® Challenge #3: 3D printed Structural Steel Connection Design
Structural Steel Connections often require carefully designed components to safely transfer loads to the ground. In this challenge we will design a 3D Printed Structural Steel Connector to transfer loads between a set of structural steel members to the ground. The design must be such that it can accommodate bolted or…

Altair Twin Activate® Challenge #2: Physical based modelling of a mass-spring-damper system
Modelica is an equation-based language that is especially well-suited for modeling the behavior of physical components. Activate supports several Modelica libraries, allowing users to create physical-based models, often simpler than their signal-based counterparts. Modelica components are acausal, which means that, instead…

Altair Inspire® Challenge #2: Cycling Shoe Cleat Design
Road cyclists use plastic cleats on the bottoms of their shoes to create a constant point of contact between their feet and the pedals while riding. These cleats are adjustable to accommodate different user’s preferences, and must also resist a combination of compression (downstroke) tension (upstroke) and twisting forces…

Altair Compose® Challenge #2: Batch calling OML scripts
Altair Compose is a powerful engineering math toolbox and you can script inside it to make your work more efficient. However, to fully master Compose, you must know how to incorporate it into your workflows even without its user interface and, more importantly, be able to leverage its capabilities regardless of it being…

Altair Inspire® Challenge #1: Bridge Concept Design
Have you ever looked at a bridge, and wondered what factors determine the ideal support system for such a structure? Now is your chance to use Altair Inspire to help answer that question. In this challenge we have a scaled down bridge, for which we want to determine the preliminary structural layout. The bridge deck must…

Altair Compose® Challenge #1: Plotting in Compose with different types of axes
The main scripting language in Compose, OML, features a rich set of plotting commands for creating 2D and 3D plots. In this challenge we will explore some of them as well some nice features for arranging your plots. When I was new to engineering scripting languages (Compose, Octave, MATLAB, etc.), I often was able to…
