Re: [ff3d-users] Strange error during execution

[Emilio Melero García]

Dear Stephane,

Thanks for your reply. Let us know when will you release those changes you mention (the ofstream to write text to data files and the mesh refinement...) It would be very nice. Thanks in advance for all your work!!!.

Now i would like to make a petition if possible. Unfortunately i am behind quite a strict firewall and can not access the latest source of ff3d to compile it. I am stuck with version 1pre7. Can anyone please send me the source files, or if there are some caritative soul out there riding an intel mac a compiled binary?. I would be much obliged. Please send it to 
address@hidden.

As soon as i find a little time i will explore this option that Stephane mention about interfacing with gmesh or other mesher. I will let you know of the advances.

Best regards and thank you again Stephan

Emilio

Dear Emilio,
Happy new year.

Yes. It seems to me that this memory leak occurs with the merge. Do not worry
anymore with this, I will try to fix it soon...

This is indeed possible.
1) ff3d can read tetrahedra meshes generated by external tools. It reads
meshes at the INRIA 'mesh' format or for instance at the 'gmsh' format
(http://geuz.org/gmsh/ ). Maybe you could have a look to tetgen and netgen
also.
2) I have written the 'ofstream' that you needed to write data into text
files.
3) one can execute commands within ff3d

So, if the geometry is defined with a text file, your ff3d command file can
- generate it
- launch the external mesher
- reread the mesh

I think that this should work...

In fact I have to check that everything works since mesh refinement has not
yet been tested... The problem is that ff3d's variable life time is not
local: thus a fem function declaration should change if the mesh changes.
This change might not be too tricky to code, I will have a look...

Best regards,
Stephane.
