[Sanket Jain]

Do you have a function to write the output of v2m as .mphtxt file format?

It's a COMSOL format,

I've made this, but it's incomplete

@ Kim: Can you share it with me whenever you are done?

hi Kim

I just want to add that it is always welcome
if anyone want to contribute to iso2mesh.

It would also be great if the contributed unit
contains a small section of help info. Please
open any existing iso2mesh .m to see the general
format.

Hi all,

I've attached it. As i say, this function is incomplete.

It can load only tetra element and something wrong defining domain

When you fix it, please share it :)

hi Donghyeon

in order for other people to modify/derive based on
your work, you have to specify a license, preferably
an OSI approved open source licenses, see

http://www.opensource.org/licenses/category

Specifically, because iso2mesh is licensed under
the GNU General Public License (GPL), to be included
in iso2mesh, the contribution must be licensed under
a compatible license (GPL or a permissive license such
as BSD/MIT/X11/ApacheV2 etc), although it is purely
your choice.

Would you please send another copy of your script
with the license clarified at the header of the script?

Please forgive me for the formalness on the license
matters, but this is necessary for any open-source
software to grow.

hi Qianqian

I've attached modified version, It's first time to share my own code to everyone on online

So, I didn't know what prepare before share my code,

I've written "this function is part of iso2mesh toolbox (http://iso2mesh.sf.net)", 

It's ok? i think, because iso2mesh follows GPL license, when i say this function is in iso2mesh toolbox, it will follow GPL license.

[김동현]

Oh, i missed my code.

this is.

As recommended by GPL, every unit should carry a
header to show it is GPL licensed. Since I have your
agreement, i will add this info to the code.

Sanket, can you help to test this unit and let me know
if this works for you?

thanks for both of you.

Sure. I will do that.

When I import the output of the script, I get the following error: 

Exception:

com.femlab.jni.FlNativeException: Incompatible native file version

Messages:

I am in the process of moving away from using mphtxt converter. Instead I am using native Comsol 4.1 functions with other 3.5 matlab functions to read my mesh into Comsol 4.X version. It works for smaller meshes. I have to try for larger meshes but I believe the same methods should work for them as well.

Hi Sanket, i've tested your data,

It occurs same error in my comsol 4.1

But it's ok to use in comsol 4.2

No error and problem to load.

And you said "comsol 4.1 functions..." it means you use Matlab
LiveLink for Comsol?

[Sanket Jain]

Yes. I mean Matlab LiveLink. I would love to use this function instead of LiveLink. Do you know what could be problem in 4.1?

Sanket

[Daniel_Kim]

This code is based on .mphtxt structure.

And maybe comsol 4.1 don't have a compatibility to other
version's .mphtxt format

below site, show how comsol .mphtxt is formatted

http://www.comsol.com/community/forums/general/thread/3479/

So, if you want to load .mphtxt file to comsol 4.1, make a mesh and
extract .mphtxt from comsol 4.1

and check what is different, i know it's annoying.

But comsol doesn't provide the exact format information of .mphtxt, so
we should check it manually.

That's why my code is uncomplete.

Donghyeon

[Sanket Jain]

I tried looking at the mphtxt from 4.1 and compared with your format in script as well the O/P file from your script. But unfortunately, I can't find anything wrong/missing. I don't have access to 4.2 version. 

@ Dr. Fang: I have Matlab function which reads node, face and elem matrices and writes mphbin/mphtxt file. Note, this function requires Matlab 
LiveLink with Comsol. LiveLink is an addon with Comsol Software. Feel free to modify the code
