[Scilab-users] FEA in Scilab

[Heinz Nabielek]

I would have no idea, if the report

"Finite Elements in Scilab: Solution of partial differential equations supported by the FreeFEM toolbox"

is any help. Dr van Seggern is long retired from the Forschungszentrum Jülich.
Greetings

I am worried about attaching such a document to the User Group here in general, but I can of course send it on request. In Mecway the axisymmetric model is expanded into 3D with hex8 elements (it looks like a basic cubic element). The force-function is applied in 40 time steps. It looks like 40 x basic static analysis.
