I need to draw an ellipsoid which has three semi-axes (assume a,b,c) and three Euler angles( assume alpha, betta and gamma), it's worth mentioning that I need to generate this ellipsoid by ABAQUS and not any other softwares e.g SOLIDWORKS, CATIA and ...
I tried to do it as following approach but there is a problem;
I draw an ellipse and try to revolve it by 360 degrees around the vertical axis, but by this approach, there is two semi-axes with same length and i cannot define length of 3rd semi-axes.
Any advice and suggestions will be greatly appreciated.
you can draw almost anything if you Know the Coordinate of points which then can be connected through lines. if the function is known you can get the points w.r.t your function then you can draw it in catia V5 and import it as IGES file Formate. i have done this to implement Complex delamination shape from D-scan through this method.
Dear Mr Qaimari,
Thanks for your response,
I could understand what you means, but as I have mentioned in my question, I want to draw this ellipsoid directly by ABAQUS and this is because of some problem which compel me to draw it only by ABAQUS.
Dear Mr. Maleki,
You can try to use the "Solid Loft" feature from the Part Module. The feature input are Cross Sections (in your case, elliptic sketches that can be generated using "Spline") and a Path/Guide curve (also elliptic, for an ellipsoid case).
Dear Mariana,
Many thanks for your response,
I utilized a solution already which was same what you said (to simplifying the problem, I tried to use this approach for a sphere at first) .My solution was as following;
1-Creating two spheres by "wire" option in part module.
2-Creating a spherical path by "wire" option again.
3-Try to use "Solid Loft".
But when I select the the spherical path, I get an error which its picture has been attached.
I also have attached a picture of my modelling. Have you tried this kind of modelling by yourself by now?
Create the wire features first on the 3 principal planes (create the first, then create the datum planes for the other 2 principal planes and select Shape > Wire > Sketch to create the other 2 wires), then create your faces (Tools > Geometry Edit > Face > Cover edges -- do for all 8 regions and make sure "Try fitting an analytical surface" is checked at the bottom of the viewport), then Shape > solid > from shell and select your 8 faces.
Dear Austin Edward Cox,
This matter had busied my mind for a long time that is why I needed to do it for my thesis, but I got forced to do it in another way at that period, however that way was not exactly what I was looking for, after two years you finally gave the solution. Great thanks for your help.
Good morning,
hwo could i cut an ellipsoid from a part which got also 3 differents semi-axes.
thanks.
Amina Ayadi, You can draw "your ellipsoid" and "your part" in two separate parts, then cut out your ellipsoid from the other part by Assembly Merge/Cut tools, you can find this option in the instance tab.
