[Scilab-users] FEA in Scilab

[Claus Futtrup]

Hi Michael

I'm the thread starter. Good point that one could look in MATLAB for 
inspiration.

I am not so much interested in creating a FEA program (or API) myself in 
Scilab, but if anything exist today which to some extent is in 
development or service (maintenance), then I'd be inclined to try this.

... Conclusion seems to be, this is not the case.

Best regards,
Claus
