Risa isn't suited to the kind of analysis he needs.
NOTE: I'm not picking on Risa. The statement applies as well for most of the mainstream structural analysis programs. Their Finite Element capability is limited.

I began assuming we could use that and we have ended up with some point load conditions I no longer feel comfortable using Roark's with.

Woiuldn't Roark and a spreadsheet do the job?

Surely ANSYS would work for us if we decide to spend so much, but we don't have any students on staff and don't have access to the student version (not to mention this is for professional use.)
Thanks for the response; it still answers my question in a sense as it sounds as there are no 2D analysis software. I will check out the LISA software suggested by Conrad.

If I understand you correctly, you wish to acquire a small-capacity
FEA program that costs little.
First of all, most codes I know are 3D, which means that if you wish
to limit yourself to 2D, you would be able to solve larger problems.
Many claims of ease-of-use are made, but the fact remains that
if you have a couple of examples on hand, everything becomes easy.
With this in mind I would recommend that you get a student's version of ANSYS.
For about $100 you will have a hell of 2D capacity.
(I may not be current with the price.)
I need to do some calculations for interior structural glass for a client.
We don't have FEM software since we normally do 2D frame analysis and so
would like a recommendation for basic (planar) FEM analysis.
Budget for this software is tight since we won't have a large
quantity/complexity of this kind of work, so cost and ease of use are
I appreciate your thoughts.
