If you've access to FE related journals can find reviews which will help, was just looking at Cubit and gmsh meshers for something else and those actually have something which relate to this topic, on a principal level:

I assume you've got a cae model? You can get the ascii input file with nodal and element information by creating a job in the cae "job module" and writing the inp out. If your problem is something else elaborate.
How about doing it in 2D by borrowing elements from plane stress/strain or carrying out the whole exercise in 3D (going for example for wedge or tetrahedral elements, would probably be almost simplest for bilinear bricks)?
For future ref if nothing else ... If you've multiple parts, you can for example make a list of them (if don't want to refer explicitly by name), followed by a for-loop which contains the part, seed and meshing specification. Something along the lines of:
for part in model.parts...
Probably the simplest nominally applicable potentials would be some variants of Tersoff nature (LJ certainly not), but for actual work would try to seek something which would be founded on some newer potential families.
The original shape you mean? Ease of testing (e.g. attaching to machine), uniform stress state at the section of interest, size for that section which for typical materials yields a representative (size independent) result to name a few. One of those things that has just evolved out of practical...
It's a nice extension --- occasionally have to work with OO (or those other office suite) documents and now at least the equations look decent. No redundancy there. A typical case when have to collaborate with uninformed people :wink: .
You'll get a whole lot more done :wink: . Comparing languages and "stating" what is needed is always a bit arbitrary (at best), but in "general terms" when learning to do things and so forth Fortran isn't quite as useful as Python (unless everything in your field is written in Fortran for some...
Thinking about tools which enable to carry out "research tasks" as effectively as possible with a wide range of applicability (thinking about code performance, "usability" of the resulting code and development time) would pick a medium level language like C++, then Python which is actually kind...
It can with some limitations, the foremost being that using the "basic" methods (nodal release types) you need to pre-define the crack path and then you can use different criteria to drive the crack propagation during the analysis. Paris' law is one of them which might be of use. Some of the...
Yeah, the reset is what it is in terms of cleaning the m - file. Haven't come up with any other way than to mix text editors with highlighting and scripting to script m - files (i.e. generate m - files using python/perl so don't have to repeat everything every time or resort to too much copy -...
