Free CAE software CALCULIX

  CAE programs based on the finite element method are an important tool for every designer and FEA engineer.  Most of the implementation departments (RnD) of companies producing high-tech devices / machines have CAE-type engineering support software. However, it often happens that due to the price of commercial programs using the finite element method, companies simply cannot afford such tools to increase design efficiency. Therefore, the appropriate alternative are CAE programs of the OPEN SOURCE type, thanks to which companies with less financial potential are able to compete with hegemons in the markets.

Free software for Structural Analysis 


What are the benefits of using the CALCULIX  program?

In these programs, first of all, structural analyzes are performed to calculate the strength of structures.  Increasingly, these analyzes also take into account the temperature of the analyzed elements. 
CALCULIX is a program of this type in which you can perform complex heat and strength analyzes.  It is a very advanced solver based on the finite element method in which you can combine static and dynamic analysis in one problem.  You can perform multi-dimensional coupled analyzes between dynamics, statics, temperature, and nonlinear contact and material.
Combined with FREECAD, CALCULIX forms a powerful tool for the design and analysis of complex mechanisms and structures.  It is also possible to install the software as a separate application and combine it with any CAD program.  
There is a powerful knowledge base on the internet created by non-profit scientists and enthusiasts of open source CAE.  Everyone, even a beginner engineer, is able to learn this program to the extent that it allows to perform almost any analysis based on the current state of knowledge and online tutorials.

Quick Tip: How to fix Error: GENERAL-CAR-CDR in Ansys (Fluent)

 The error message Error: GENERAL-CAR-CDR: invalid argument [1]: improper list means that there is a problem with the scheme code or the UDF (user-defined function) in your case or data file . Some possible solutions are: Save the case and data file and try to reopen it. Reset the Fluent Setup tab and try opening the mesh. Remesh the geometry and reopen in Fluent. Change the material definition from “Solid” to “Fluid” in Design Modeler. Change the transient to steady if you are using evaporation-condensation as the phase interaction mechanism. Check the syntax of your UDF and make sure it follows the new rules in Fluent 6.2.16 or later. I hope this helps you resolve the error. If you need more assistance, please visit the Ansys Learning Forum or contact Ansys Support . Have a nice day! 😊 Sources: 1. smartadm.ru 2. cfd-online.com 3. forum.ansys.com 4. forum.ansys.com In Polish  BÅ‚Ä…d: GENERAL-CAR-CDR oznacza, że wystÄ…piÅ‚ problem z kodem Scheme w programie Ansys Fluent.

Types of supports and examples - Ansys Static Structural

Supports are used to represent parts that are not present in the model but are interacting with it. Supports help truncate the domain, which helps in efficiently obtaining numerically accurate results without modeling parts of the geometry that are not of primary interest. There are different types of support available, among which you need to choose the appropriate one for your analysis. Here are some of the common types of supports and their explanations: - **Fixed Support**: This type of support constrains all the degrees of freedom of the selected entity (body, face, or edge). It means that the entity cannot move or rotate in any direction. Fixed support is equivalent to applying zero displacement to all directions. Fixed support is useful for modeling rigid connections or supports that do not allow any movement. For example, you can use fixed support to model a bolted joint or a clamped beam. - **Displacement Support**: This type of support specifies a zero or non-zero displacemen

How to define porosity (porous medium) in Ansys CFD (Fluent, CFX)

 To model porosity in ANSYS Fluent , you need to define the porous zone and the porous media properties in the setup. You can follow these steps: In the Fluent interface, go to the Cell Zone Conditions panel and select the zone that you want to make porous. Check the Porous Zone option and click Edit. In the Porous Zone panel, you can choose between two methods to specify the porous media resistance: the Superficial Velocity method or the Physical Velocity method. The Superficial Velocity method uses the superficial velocity (the velocity of the fluid if there were no porosity) to calculate the pressure drop across the porous zone. The Physical Velocity method uses the physical velocity (the velocity of the fluid inside the pores) to calculate the pressure drop across the porous zone. You can also choose between isotropic or anisotropic porosity, depending on whether the porosity is uniform or varies in different directions. Depending on the method and the type of porosity you choose,

How to... fix "gui-domain-label: no domain selected" in Ansys Fluent and MEMERR in CFX

In today's post, we will deal with another error that may occur during the analysis. The error that is described below concerns Fluent and the wrong definition of user monitors that are displayed during simulation. These can be monitors concerning the average velocity in the domain volume, the values of the maximum temperatures of the solid domains, the average values of the heat transfer coefficient from the defined planes of the model, etc. Generally speaking, today's entry is about how to correctly define monitors and how to transfer them between subsequent analyzes. Example of "gui-domain-label" error in Fluent
