Hfss Export Mesh

[Heron Mathis]

ANSYSis a software suite used for engineering simulation, including finite element analysis. It is commonly used in 3D printing to analyze and optimize designs before printing, reducing the need for physical prototypes and saving time and costs.

The process for exporting an ANSYS model into STL format involves first creating a solid model in ANSYS, then converting it into a mesh using the MESHING function. Once the mesh is created, it can be exported as an STL file by using the FILE menu and selecting EXPORT and then STL.

Yes, it is recommended to check and fix any potential issues with the model before exporting it into STL format. This includes ensuring that the model is properly closed, has no self-intersections, and has a suitable mesh density for 3D printing.

No, ANSYS is not a 3D printing software and cannot directly print models. It is used for simulation and optimization of designs before they are sent to a 3D printer. Once the model is exported as an STL file, it can be imported into a 3D printing software for printing.

Yes, in addition to STL, ANSYS also supports exporting models in the OBJ and VRML file formats. These formats may be preferred for certain printing methods or software, so it is recommended to check with the 3D printing service or software before exporting the model.

In HFSS, you can check 'Mesh Statistics' which provides information on Total mesh element count, and some statistical data of generated mesh elements after adaptive passes completes. This data is num tets, min/max edge length, min/max tet volume etc with respect to geometries in the simulation. This information can be geberated from Project Manager, go to Results > Solution Data > click on Mesh Statistics tab

I've also found the following discussion (How to export the resulting fields of a ANSYS Maxwell3D simulation) that it is possible to achieve what I want to achieve with the "write" output command in the field calculator. I've outputted mag_E using following this. Could you also comment on out to interpret the outputted file (attached screenshot)?

I noticed from this discussion from 2009 (Exporting HFSS generated mesh Forum for Electronics (edaboard.com)) that in the results folder, there are files containing information about the mesh. I couldn't find the files with the exact same extensions in my current simulations, but I can find files with extensions .stats, .ngmesh, .sf_mshdr, .sf_msh. Would it possible to ask for guidance to export and read the information from those files?

Regarding the field information, I am aware of the way to export field given a set of Cartesian coordinates that I set from the field calculator. However, would there be a way to export the field at each mesh node coordinate?

Your query is advance. Unfortunately, because of public nature of the forum, I won't be able to discuss and provide more detail on it. I would suggest you to log a service request if you have access to Ansys support. Our support engineer will connect with you one to one and may help you with query.

Thank you for the reply. I don't think I have access to Ansys support. Would there be other ways to get to the bottom of this? For example the "write" functionality is documented in the HFSS Help document. I don't think explaining the output of that would reveal too much.

Regarding the output of the Write command using Field calculator, the output shows Emag at various mesh elements which are tetrahedras. The order of the basis function determins the number of unknowns calculated over each tetrahedra.

Matlab uses a library to convert a matrix into a .dxf 3D surface. Depending on the option, the surface is either a cloud of points, or made of triangles or square patches (linking the points). (files attached)

I can open these files with AutoCAD Mechanical and even export them in other formats (ie. stp), but I would like to convert the cloud of points or the triangles mesh into a surface (mostly to reduce the size of the file).

For now I have 4 millions points (which gives me a 19MB .stp file when I export the triangle mesh .dxf file into .stp). I am planning to increase the resolution... So it is not possible to keep all the points and triangle meshs and I hope that there is a way to replace the meshs and points into a surface in order to make it easier to handle by AutoCAD, and lighter to export. (I need to export it in .stp (or similar format) so it can be used by an electromagnetic simulation software (HFSS, CST...)).

However, this element is only a small cell of 2mm x 2.2mm. I will need to create a bigger surface by duplicating the cell several times (to make a complete grating, of 50mm x 50mm, I would have to duplicate it more than 500 times... Maybe I will start smaller though!). Anyway, it would be good if it were possible to reduce the file size even more.

I first made sure the system variable FACETERSMOOTHELEV had a value of "0". Next I used the CONVTOMESH command to convert the polygon mesh to a regular mesh. Finally I used the CONVTOSURFACE command to convert the mesh to a surface.

The CONVTOSURFACE command lasted for almost an hour. The result is a surface, but quite an heavy one! (about 200MB when I export it in dwg or sat or igs). As you can see attached (pict), when creating the surface, a lot of lines were created to interpolate the points. I should be why the file is so big.

In fact, I saved it (in dwg) and also exported it (in sat and igs). But even the saved file in .dwg is 195MB big. So, it seems like my surface is a lot heavier than yours, even though I used the same commands. I am trying to understand what happened. I attached a picture of my surface so you can compare to what you obtained. Do you also have so many lines interpolating the points? In what format did you save the file?

I finally found out. There is a variable : SMOOTHMESHCONVERT which has to be set to 3 (or maybe 2). So, AutoCAD doesn't try to smooth the surface. By default it is set to 0, which results in a really long execution time and gives a smooth but really heavy surface.

You don't need to download an English version of AutoCAD or even a laguage pack if you are using a non English version. Just preceed the English command with an underscore character e.g. "_CONVTOMESH"

Use the Open command to open files created in any supported format. Use the Save As command to export parts, assemblies, drawing sheets, and 3D markups to formats read by other applications. Your license type determines which of these actions are supported.

ObjectAnything recognizable by the tools. 3D objects include vertices, edges, faces, surfaces, solids, layouts, planes, axes, and origins. 2D objects include points and lines. IDs for edges, faces, and bodies are now stored within the .scdoc file.

IDs are preserved when other files are opened or inserted into , and the IDs can also be exported. For example, if you export a design to an analysis company, and they tag geometry with load positions, boundary conditions, and so on, then when you re-import that design, make changes, and re-export to the analysis company, they will not need to recreate their tags on the new design.
