chaos is on a distinguished road
hello!

it's my first time using openfoam and i can't even import my mesh

my inputfile is a nastran bulkdata file (.dat)
the syntax is really simple:
BEGIN BULK (koordinate and number of the nodes)
GRID,1,,588062.321633,253262.321633,1798.662318
GRID,2,,588062.321633,253392.110575,1760.908129
...
(number of the hexaedra nd the needed nodenumbers)
CHEXA 140928 145776 145835 145836 145777 149257 149316+
+ 149317 149258

i found the application dattofoam but theres no documentation what file exactly.
is it for nastran datfiles? because i always get this error:

Greetings chaos,

Welcome to using OpenFOAM! Since it's open-source, you have to go straight to the source code: https://github.com/OpenFOAM/OpenFOAM...am/datToFoam.C

Or go to the code documentation: http://www.openfoam.org/docs/cpp/ - search for datToFoam.

Seems like datToFoam isn't for Nastran files, because it references explicitly in the code this:
Code:
std::ifstream plot3dFile(args.args()[1].c_str());
If I'm not mistaken, OpenFOAM can only convert surfaces from Nastran's "*.nas" files:
Code:
surfaceConvert a.nas a.stl
Best regards,
Bruno
