Re: fcFEM integration with FEM work bench

@Kunda1, I have not made much progress since early July. Partly because I am busy with other things and partly because I have focused on the first objective mentioned above, i.e. “Robust, automated solution procedures”. My solution procedures are very robust for metal and soil plasticity, but for co...

Re: structural pipes

Your question was how to connect the pipes and that post explains how to do that. What you use the model for is entirely a different matter.

Re: FEA for additive manufacturing.

The "Material Point Method" may hold more promise for this type of analysis: https://cmmrl.berkeley.edu/a-material-point-method-framework-for-simulation-of-additive-manufacturing-processes/ https://lra.le.ac.uk/bitstream/2381/43375/1/2019YANHPhD.pdf https://www.seas.upenn.edu/~cffjiang/research/mpmc...

Re: FEM-Hydrostatic pressure constraint help/request

Alex, the translation of pressure to nodal forces is taken care of by Calculix. This is quite involved for curved surfaces. If you want to see how it is done you can have a look at the fcFEM source code. However, as I said, this should not be necessary. The DLOAD card only requires the pressure and ...

Buckling and Free Vibrations (without integrals or matrices)

An interesting challenge from Bernd (https://forum.freecadweb.org/viewtopic.php?f=18&t=37400&start=20#p319473) ... ... do you know some paper which explains all this without tons of integrals and matrix operations ... Attached an attempt at this for the interested reader. Buckling and Free Vibration...
