为分析者开发的MeshFree软件，能够超越网格划分的局限性。分析者在做分析的时候，网格划分往往是不可避免的工作，网格划分的局限性会直接影响到整个分析。MeshFree软件利用结构化网格，工程师不需要考虑几何模型的复杂性，不需要网格划分，能够快速得到分析结果。
复杂的CAD模型不用简化就可以分析
FEM方法在分析复杂结构的时候，得到高质量的网格会很困难，所以会导致得不到准确的分析结果，但是MeshFree采用的是结构化网格，这种结构化网格会在结构曲面上自动形成边界，无需考虑CAD模型的复杂性，无需进行网格划分就能够得到理想的结果……………
MIDASoft has released MeshFree 2024 R1. This technology performs finite element analysis on the original CAD model without need for meshing or defeaturing.
MeshFree 2024 R1 Release Note
Improvement of Geometry-Fitted Grid Application Functionality
MeshFree generates the grid based on the IBM (Implicit Boundary Method) algorithm and proceeds with the analysis. In the previous version, an issue was identified where the geometry-fitted grid application only worked correctly when slender members with large cross-sections compared to their thickness were aligned such that the X, Y, Z axes were rotated 90 degrees relative to the global coordinate system. This issue has been resolved to ensure proper grid generation for thin plates and other geometries with misaligned orientations. The coordinate system alignment has been improved to handle these cases correctly.
Other Bug Fixes
< Improvement of Negative Coefficient for Hyper-elastic Material Distortion Constant>
An issue was identified where it was not possible to apply negative coefficients for higher-order terms related to the distortion constant of hyper-elastic materials. This has been fixed, allowing both positive and negative values to be applied.
< Addition of Reaction Force Results for Rigid Body Master Nodes>
It was found that reaction forces at rigid body master node locations were not being calculated, making it impossible to verify reaction force results. This calculation procedure has been added, and results can now be checked.
< Improvement of Plastic Strain/Stress Results for Elastoplastic Materials>
Abnormal values were observed at certain discontinuous locations for elastoplastic materials. Improvements have been made to the accuracy of plastic strain calculations and the equivalent stress calculations related to the strain-stress curve.
< Addition of Exception Handling for Convection Conditions in Linear Contact >
In thermal analysis, convection conditions are set for external air contact surfaces. However, with increasing geometric complexity, manually removing these conditions at contact locations has been inconvenient. This has been improved so that convection conditions are automatically ignored when linear contact conditions (bonded, sliding) are present.
< Application of Unit System to Reference Points for Distributed Loads and Edit Box Revision >
An issue was identified where reference point coordinates for distributed loads were calculated with a fixed unit of millimeters. The unit system issue was addressed for the entire edit box, including this location, and has been corrected and verified
Support for the latest version of the CAD interface may be delayed depending on the supplier’s update environment. If the newest version is not supported, please convert it to a neutral file such as Parasolid or STEP file format. We will do our best to reflect on the latest version of CAD quickly
midas MeshFree is a cutting-edge design and analysis technology developed through the collaboration with SAMSUNG Electronics. It performs simulation of the original model you have designed without any modification. Conventional FEM required tedious and time consuming model idealization and cleanup process. However, MeshFree has the latest, efficient and effective numerical analysis algorithm that can simulate using the original 3D CAD model itself.
The webinar will introduce and demonstrate main features of midas MeshFree. Check what advantages you can take for your competitive edges.
In 1989, the MIDAS team was formed to resolve engineering issues by developing software within the steel company. MIDAS saw the importance of engineering software to ensure safety and performance. Since then, MIDAS believes providing better technology for engineers will ultimately contribute to people’s happiness around the world. With this belief, MIDASoft was established in August of 2000. Initially, midas Gen and Civil software were introduced to serve structural engineers. Today, MIDASoft continues to empower engineers in the bridge, building, geotechnical and mechanical industry, and more.
