Midas MeshFree’s proprietary IBM
(Implicit boundary method) algorithm
is a technology that enables accurate analysis without the need to create meshes, which allows design engineers to simulate intuitively. MeshFree created a new innovation with making the creation of meshes unnecessary.

WHY MeshFree The purpose of
simulation is to find and
solve
problems
in the design phase.

During the design phase, it is very important to review
the various designs. The more you validate your design with virtual prototypes, the more you can help reduce overall costs.

Optimal design quickly
and clearly with quantitative
values derived by designers
Meshfree supports you to make
decision quicker in situations
when the
conditions in the design stage constantly
change by quickly deriving quantitative
values based on the changed CAD model.
This also supports you to try our
more free and innovative designs
in the linear design stage.

The result value comparison function is a function that allows you to compare and analyze various design changes in one window.
You can check the stress maximum value, minimum value, volume, and mass change. Through the synchro alignment function, you can simultaneously move the comparison model to a desired angle and use it in a variety of reports.

Verification you can trust Easy but accurate
midas MeshFree

MeshFree has completed reliability verification tests by the National Association for Mechanical Engineering (NAFEMS) and the Samsung Global Technology Center.
In addition, its accuracy has been verified by various official machinery organizations such as the National Federation of Technical Societies and Public-Private Joint Investment Technology, and many companies are using it.

  • What are the minimum system specs?

    Minimum: Ram 16GB / CPU intel i3 / HDD - 100GB or more free space / NVIDIA Graphic card required / OS - Windows 64bit
    Recommended: Ram 32GB / CPU intel i5 / HDD - 100GB or more free space / NVIDIA Graphic card required / OS - Windows 64 bit

  • What is the difference between CAD embedded software and Meshfree?

    The analysis purpose of CAD embedded SW is for designers to easily analyze. However, it is the same regardless of SW that designers have to go through mesh and clean-up for analysis and there are many things to know. Meshfree is a program with high scalability for designers by minimizing the time required for analysis and the information they need to know.

  • If it can be used without specialized knowledge, is it possible to perform difficult analysis?

    MeshFree is basically equipped with FEM level analysis function. In addition to linear analysis, modal analysis, and heat transfer analysis, which are mainly used in the design stage, all analyzes including nonlinear static analysis and dynamic analysis are available. Even for advanced analysis, it is easy to use based on the 3-step process.

  • How is the tendency/accuracy of the analysis results between Meshfree and FEM?

    The tendency appears to be the same. However, while FEM involves a high-cost work called Mesh for analysis to determine the degree of tendency, Meshfree can perform everything from tendency analysis to precise analysis only by adjusting the grid size. In the case of the Korean Society of Mechanical Engineers verification model, the error rate is around 5%, and NAFEMS also performed verification with FEM. However, due to the characteristics of the product, it is more useful to use MeshFree to quickly compare and review various design proposals in the early design stage to understand the performance rather than to derive precise results.

  • How do you mainly use MeshFree?

    MeshFree is mainly used when you want to check the performance of a product at the design stage. I n the case of Samsung Electronics and LG Electronics, designers are using it as a way to find and solve problems by identifying product performance in advance centered on designers in the design stage, and through this, they are innovating the design process.
