Quick Updates

This post is a quick listing for the new videos that were uploaded recently about the fantastic mesh.

Latest video is a speedy video about bank of tubes modeling in Fantastic Mesh

The theme played at background is a famous theme that I used to hearing it in 90’s .. I am not sure if the theme is international or national to Egypt .. but it is quite awesome.

 

Second Video is for modeling and exporting to OpenFOAM ..

This video is very interesting .. I am going to post about how did I manage to export to openfoam in a separate post afterwards.

 

Third Video is for cyclone modeling using my brilliant fantastic mesh modeler (am I biased here ?!!! 🙂 )

 

Fourth Video is a short video illustrate the extrusion process using custom expression. (quite interesting 😀 )

 

Well .. this was a quite long post and many videos.

 

I am about to defend my thesis .. hopefully on the end of this week. a lot of corrections needs to be done.

 

until we meet again .. enjoy those videos

 

and don’t forget … 😀 …   subscribe to the fantastic mesh in facebook  https://www.facebook.com/pages/Fantastic-Mesh/567869366677159

Ability to load wavefront models *.obj files

I’ve added a cool feature in my program .. which is the ability to load wavefront models

check this video

I am recording this post to remind myself with strange behavior of the .obj format

which is the indexing with negative indices

I mean a line like this one

f -28 -44 -31

this line indicates that this face is having three vertices .. their indexing is not absolute

but rather relative from the last line of ‘v’  or vertex

so actually you can find the following lines

v -109.591 77.4386 -352.207
v -110.289 77.4687 -353.25
v -110.723 77.4046 -354.151

# and then

f -1 -2 -3        # which is relative in backward fashion for the vertices above

whatever .. this is a quick post about my latest feature on the program

enjoy

Fantastic Mesh My Master Software

Fantastic Mesh is my Master software

My Master thesis title is “building interactive CFD grid meshes for Complex Domains”

 

and for this purpose I created this package

I am trying to understand everything I could about CFD .. meshing .. Geometry .. manifolds .. and literally every thing

 

I am hosting the software as a private repository in http://bitbucket.org

however the repository now is private until I get my master degree.

hopefully I can post on this blog my discoveries in programming .. mathematics .. geometry  ..  and my problems solutions for many areas during my writing to this software.

today I implemented loading of wavefront object format  .. (unneeded feature but I liked it)

what’s else …

let me link to the youtube videos I made for the software

This is the first Video I posted

and this is the second video

 

something also that is related to geometry is getting the Metric Tensor .. I wrote this nice article about this subject

http://quantitysystem.wordpress.com/2012/04/29/metric-tensor-in-quantity-system/

 

 

at last

quite short post ..

but I couldn’t handle to let the blog empty ..

so

meet you later with more throughout posts .

 

Cheers
