Faster CFD meshing and handling of complex or low quality CAD Geometry <\/h2>\n\n\n\n

A new \u201cMesh Boolean\u201d technology enables you to handle complex and extremely bad CAD geometry even faster and easier than before. When CAD Boolean cannot conduct Boolean operations successfully because of bad or dirty geometry (bad topology with missing entities, self-intersecting faces, etc.), the Mesh Boolean option can be used. <\/p>\n\n\n

Mesh Boolean first meshes bodies separately and then conducts Boolean operations of the meshed bodies without using any CAD Boolean operations. This technology can prepare and mesh, even very dirty models, 5-15 times faster <\/strong>and easier without any user prior adjustments or healing of the model, i.e., automatically. <\/p>\n\n\n

In previous versions “CAD Boolean\u201d is the default option. \u201cPreprocessor Boolean\u201d is FLOEFD\u2019s Boolean approach activated with \u201cImproved Geometry Handling\u201d. The new Mesh Boolean technology can be used together with the CAD Boolean diagnostic, combining the power of Mesh Boolean and the convenience of getting additional information, such as a diagnostic of the fluid domain. If the CAD Boolean diagnostic fails to detect the fluid domain, you still can proceed and mesh the model with Mesh Boolean. In that case additional subdomain diagnostics will be displayed in the Solver Monitor dialog. You are free to choose the default way of handling the geometry (CAD Boolean, Preprocessor Boolean (formerly called \u201cImproved Geometry Handling\u201d mode) or Mesh Boolean, as well as you can disable the CAD Boolean diagnostics<\/p>\n\n\n\n

1D Elements in 3D CFD – speed up simulation with multiple chains<\/h2>\n\n\n\n

1D Elements were introduced in Simcenter FLOEFD 2021.2.<\/a>1. These allow you to simulate a pipe with a 1D solver. You can convert a pipe into a chain of 1D Elements and solve their fluid and thermal interactions using 1D CFD embedded in 3D CFD Simcenter FLOEFD. This allows you to increase simulation speed and reduce mesh requirements.  The 1D Elements feature doesn\u2019t require any module or additional license and now you can create multiple chains with this release. Take a look back at this blog<\/a> that introduced 1D elements for introductory information and a video. <\/p>\n\n\n\n
