This tutorial covers how to convert an STL to a STEP using FreeCAD. Note: Since STLs are meshes, the resulting model won't be as precise as parts originally made as solids. FreeCAD can export: - Step - Iges - Scad - Dxf - Dwg - Obj - Pdf And many others…

I found today a post from a friend (Nuno) asking how to solve this issue, converting an .stl to solid .ipt. Then I remembered that I found something in the past regarding this conversion... Yeap! it was in Autodesk Labs So let me explain with couple of easy steps how this works...

Learn how to use SesamX, Salome and FreeCad to create a finite element simulation of a car wheel rim. This tutorial is composed of 4 steps: 1) How to prepare the rim geometry for meshing using FreeCad. 2) How to mesh the rim using Salome. 3) How to analyze the rim deformation using SesamX. 4) And how to visualize the results using Salome. You can consult the detailed wheel rim tutorial for a deeper presentation: https://www.sesamx.io/doc/tutorials/car_wheel_rim The geometry used for this tutorial is provided by Henry: https://grabcad.com/library/car-rim-132

FEA is not a simple mathematical operation. Instead it is a computer-based iterative numerical technique along with inevitable discretization errors, as a function of elements. Therefore these errors can be reduced by... specifying more elements (H-refinement) or employing a higher order of polynomial at each iteration (P-refinement). Effectively more computational power is required to solve complex shaped geometries with high dense mesh (Elements). But how dense should be my mesh to get appropriate results without wasting hours on simulation ??? This is the Golden Question! ... There is a criterion for that, called Converged solution... In plain words the mesh does not need any further refinement (denser mesh) as long as the solution is "Converged". The solution is assumed to be "Converged" when the results of the polynomial eq. does not change according to a prespecified tolerance e.g. 10% Good Results, 0.1% Great Results. So, let me share some information how to manipulate the mesh for a model along with three examples. As a conclusion we will enhance your confidence regarding the results you get, whether are relatively accurate or not (Low Percentage of Discretization Errors) without wasting hours on simulation!!! Don't Forget the simulation results are nothing without any experimental results to compare with.

https://youtu.be/XQ0Q6M66ToM This tutorial shows you how to transform a multi-patches surface into a clean surface. With the surface simplification functionality, you can merge patches together and obtain a proper surface. Combined with the healing feature, you fill the small gaps and connect all the patches together. To verify if the surface you can offset it to see if it is fully healed. The final step is to open the SIMULIA Structural Model Creation application, to mesh the surface and see why is it useful to clean the surface first.

https://youtu.be/dnP31eBoB4g Hello All! Today I present you a SIMULIA 3DExperience R19x Tutorial! You will first design a pipe using CATIA. Then copy you will insert abstraction shape to copy the original part. The partitioning will be performed in the abstraction shape. We will add material and then apply a quad-dominant mesh to our part.

https://youtu.be/P2kIKmlpzbo Hello Hello! Here is another video about SIMULIA 3DExperience R19x! 2 weeks ago I published a tutorial for SOLID meshing in SIMULIA Application (https://youtu.be/dnP31eBoB4g). So this time it will be about SURFACE meshing. It is a bit different because the partitioning will be performed on Generative Shape Design with the feature split. You will copy the original design in the abstraction shape and apply a material to the 3DPart. Then you will finish by applying the mesh to the surface by using the constraint lines previously created from the split. Do no hesitate to add comments or send me message about new topics for instance! Please subscribe and visit our website: http://www.plm-technology.com/ Use Captions and Enjoy :)
