Considerations for solver selection Altair Feko is a powerful tool featuring a variety of solvers for a vast range of problems. As a result, it could be difficult to decide which solver is the most suitable. In an ideal world, the choice of the solver should automatically be made by Feko - this objective is currently under…
Create an Implicit Primitive Create simple geometric shapes that can be used for repetitive tasks or combined into more complex shapes. Implicit primitives include a cuboid, cylinder, and sphere. Each primitive type has controllable position, orientation, and dimension. Implicit Primitive Shapes are, * Cuboid * Cylinder *…
Implicit Modeling Example 1: Creating a Sphere with Gradient-Based Lattice Structure This example creates an implicit 3D model, calculates its gradient, and uses that to generate a lattice structure on the sphere. from hwx import inspire from hwx.common.math import Point inspire.newModel() # Creating an implicit part.…
Bushings Create bushings between the selected surfaces of the parts. With bushings, you can create connections with multi-directional stiffness and mass properties between two set of surfaces of two parts. This helps capture the physics and more accurately correlate results within an assembly. Creating Bushings and Modify…
Altair Compose is a tool that can enhance our usage of other simulation tools. In this small post I will show you how you can use it to run multibody systems simulations using MotionSolve and animate your results in HyperView, all with a single click. This example is based on the Python script shown in Drive MotionSolve…
Fasteners Fasteners connect parts together without allowing movement at the hole location. Creating Fasteners When defining fasteners, you can create grounded bolts and grounded screws that act as supports in load cases. A grounded fastener mimics the nut and bolt or screw being fastened to another part that is not…
Question: The PsBios library currently generated in COFF format. Would it be possible to generate it as an EABI library? What are changes need to be done in order to make it possible? Answer: PSbios libraries are in COFF format, plus SimCoder generated code, and related link files use COFF format, too. Customers cannot…
The use of equivalent sources in Feko is helpful in many cases to significantly reduce the runtime and memory required for simulations. In principle, a model (classically an antenna/array etc.) is replaced by the radiated field (near field or far field), which is then used instead of the antenna/array in other models.…
Overview This project presents the Mok Fluid-Structure-Interaction (FSI) Benchmark solution with Altair® Radioss®. The project includes: * 2 models with different formulation techniques: * 1 CEL model with multi-domain option set up * 1 ALE model with coincident mesh * All models have been set up with Altair® Radioss®…
In this video we will discuss how to simulate contact between disconnected members using S-FRAME. This involves the creation of Rigid Body Constraints, and Compression Only Springs to simulate bearing contact. More information on this topic can be found in our Nonlinear Analysis Training Course available on demand at our…
