MegaCADs
 
Has anyone any experience of MegaCADS ?

http://www.megacads.dlr.de/

I can see very little reference to it on this forum , or anywhere for that matter, I'd be interested to know whether anybody has got it running and therefore its worth my effort in installing a suitable OS.

I suppose getting to export something that Openfoam would understand would be the next challenge...

Hi!

I'm also trying desperately to get this software to work.

I've emailed them, but I can't access the ftp address they provide.

Do you know how to go about it?

Any help would be great!

Fill in the online form and they email you some usernames and passwords.

Just navigating to the ftp site does not enable you to download it, but if you use a client like Filezilla and enter a username and password you get access.

Hi there,


I used MegaCADs whilst working on my bachelor thesis at the DLR. I was using it in conjunction with the DLR Tau-Code, thus I am not quite sure if it's easily possible to export the grids to a format which can be converted to OpenFOAM format.

MegaCADs is pretty good for generating block-structured meshes but the learning curve is very, very steep. I've written a small tutorial for this piece of software, but unfortunately it is entirely in german.

In a nutshell: if you're looking for a grid generation software for creating structured grids around more or less simple geometries and don't have problems with facing the troubles installing and using it, then go ahead, I strongly recommend it then.


If you have further questions feel free to ask.


Greetings,
Felix.

Hello,

This presentation gave me an first insight into MegaCads:

I feel free to ask you Felix, if you could provide me the mentioned paper in my native language ;)

MegaCads
 
Is this software still available ? The website has no
link for downloading and the last post on this forum
regarding MegaCads indicated they do not answer
email. Looks interesting though.

Yes, it is still available. About one month ago I contacted the DLR MegaCads-Team via megacads@dlr.de and received a copy.
I'm running it on Ubuntu 14.04 64 bit.
Right now I'm working on a mesh conversion utility to convert MegaCads meshes into OpenFOAM PolyMesh-format.

regards

That's good to know dhbw. Do you plan to make the
conversion utility available?

dhbw October 15, 2015 06:37

If I get it right some day I will:D. Single-block works already though I'm still working on multi-block implementation. Did you get your MegaCads copy in the meanwhile?

Guess I need to mention, the conversion utility is written in Scilab script language. So you will need to have that too. I bounded it to Scilab since I'm using MegaCads meshes in an own Scilab CFD code.

In the meanwhile I rewrote the tool in C++. Much quicker now and it also includes some fancy mesh-manipulation-schemes such as revolution or extrusion of 2D meshes.
Currently supported output formats are OpenFOAM BlockMeshDict (ASCII) and Tecplot (ASCII). Input has to be provided in MegaCads (FLOWer) format at this time.
I hope I can make it available soon and maybe it can help making MegaCads or "real" structured meshing a bit more popular (in terms of freely available OpenFOAM meshers).

Hello dhbw! If you decide to make it available, could you post here the link? We'll be very grateful to you! :)

dhbw September 15, 2016 11:25

Hello galogen,

actually, the current version is ready to publish and under heavy use in our research. Unfortunately, I'm still waiting for permission to make it officially available. But I'll put the link here asap.
