[GiDlist] Wave based method
Posted: Mon Dec 02, 2002 11:46 am
Hello,
I'm doing research on a new deterministic prediction technique, based
on wave based modelling. For this I'm looking for a user friendly pre-
and postprocessor. After having a quick look at GiD, I think it just
might be what I'm looking for, if the following things are possible.
Since for the wave based method, I only need a very rough discretization
of my problem in covex, homogenous subdomains, I only have a few large
elements. Up till here, no problem, but my domains can have other shapes
than three noded and four noded elemens (2D). For instance I can have six
or
seven noded elements (2D) or more exotic elements in 3D (with for instance
15 nodes). So my question: Is is possible to add my own elements to GiD ??
An alternative I thought of, is to use geometric entities as elements.
So assigning boundary conditions, loads and material props only to points,
lines, surfaces and volumes. Is this possible and is it then possible
to export this information with a *bas file to a *dat file, like is done
with element and node information ?
Thanks in advance,
Bert
