- I am posting this for someone who was not able to post on the net. I found
- it very informative.

- There are, as noted in the original posting, several commercially available
- Finite Element packages on the market. In addition to ABAQUS, MSC/NASTRAN,
- and ANSYS, all of which are good packages, but with different capabilities,
- and markets, there are a considerable number of less well known packages.
- Some of these are specifically for the IBM-PC platform (such as ALGOR), and
- some have better dynamics capabilities, or buckling, or thermal capabilities
- than others. There is even a P-version code out commercially, called RASNA,
- which is very good.
-
- For the practitioner who needs to make a rational decision about what package
- to purchase, the first oder of business is deciding what type of problems
- will be solved with the package. It is not really as easy as just deciding
- which is best, each of the packages has its good points and bad points.
- ABAQUS is an extremely good non-linear code, but is overkill for the more
- common linear elastic problems. MSC/NASTRAN is very good at the airplane
- kinds of analysis, as one might guess (linear statics and dynamics). ANSYS
- seems to be good for the power plant and automotive industries. If a small
- commercial shop has AUTOCAD, then ALGOR might be the best answer.
-
- If I might make a suggestion, the Computers in Engineering Division of ASME
- puts on a conference each year, which deals in part with this issue. There
- is also an exhibit with the conference with participation from most if not
- all of the larger commercial FE vendors. I happen to be the Chairman of the
- conference this year, and would be delighted to see this whole issue brought
- up and fully discussed at the conference. It will be in San Diego in August
- of 1993. I can email anyone a copy of the call for papers that wants one, or
- I would be delighted to respond to any other requests for information.
- Alternatively, if anyone is interested, I have been in this business for a
- long time, and can help the uninitiated. Those that have been around for
- some time I hope will understand that I am somewhat reticent to engage in
- what always tends to be a religious war. That is, the choice of the "BEST"
- finite element package. There is NO BEST ONE. It all depends on the problem
- that is to be solved, and the analyst's abilities and proclivity.
