Re: [Scilab-users] FEA in Scilab
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 On 30.01.2020 14:59, Michael J.

Re: [Scilab-users] FEA in Scilab
Hi Denis I did a search in their documentation (it's offered on their web pages) for Scilab, and only found one hit which explains their arrays are set like matlab or scilab. Searching their modules library for "scilab" returned empty. I did a google search "scilab site:freefem.org" ... but nothing hints that freefem is somehow supporting integration with Scilab. Am I wrong? (Any pointers?)
