When you use FEA (like with Calculix or OpenRadioss) on a pressure vessel, you get a full, complex distribution of stress through the wall thickness. However, global design codes like ASME BPVC Section VIII, Division 2 (Design-by-Analysis) and EN 13445 classify stresses into categories based on how they contribute to Read more
In the demanding world of Finite Element Analysis (FEA), performance is king. When tackling complex engineering problems, especially with large datasets and intricate geometries, how efficiently your software scales with increasing computational resources can make or break your analysis time. This is precisely what we set out to investigate: a Read more
Fire. It’s a powerful and destructive force, and understanding how structures behave under its intense heat is crucial for ensuring safety and minimizing damage. This is where fire resistance testing and simulation come into play. One of the most widely recognized standards for fire resistance testing is ISO 834, and Read more
The building industry is increasingly focused on energy efficiency, and windows play a crucial role in a building’s overall thermal performance. The Italian standard UNI 11673-1-2017 provides specific requirements for evaluating the thermal transmittance (U-value) of windows and doors. One powerful method for achieving this analysis is using Finite Element Read more
Finite Element Method (FEM) analysis relies heavily on the choice of element type. The accuracy and efficiency of your simulation depend significantly on selecting the appropriate element for your geometry and loading conditions. Three fundamental element types are BEAM, SHELL, and SOLID elements. This post explores the differences between them, Read more
A new benchmark to evaluate performance of two of the most common FEM/FEA solvers is proposed. On the cloudHPC platform it is possible to execute both calculiX and code_aster simulations with the most advanced MPI compilation. None of the two solvers is, in fact, available in multi-core use – also Read more

Detailed Steps (Example with OpenFOAM’s pimpleFoam and Calculix) 4. Key Points 5. Advanced Considerations 6. Getting Started Feel free to ask if you have more Read more
Converting an Abaqus input file (.inp) to a Calculix input file (.inp) requires manual intervention and some understanding of both software’s syntax. There is no automatic conversion tool available. Here’s a step-by-step guide on how to approach this conversion, along with common issues and solutions: 1. Understand the Key Differences Read more
Introduction Fatigue analysis is a crucial aspect of engineering design, ensuring that components can withstand repeated loading cycles over time. CalculiX, an open-source finite element analysis (FEA) software, provides a robust platform for performing fatigue analysis. In this guide, we’ll walk through the key steps to conduct a fatigue analysis Read more
CloudHPC has now expanded its functionalities with regards to Calculix. This is a Finite Element Software very popular in mechanical engineering applications that allows to execute a number of analysis such as: All these analysis can be linear or non linear in terms of material, geometry or contact between parts.
