Calling user subroutines in shared libraries

[MojtabaFarrokh]

Hi,

There is a good option to call UMAT in shared libraries. It does not require any modification to CalculiX, is generally easier to set up and is very flexible. I wonder if this functionality can be used for the other subroutines like “dload.f”.

Let’s assume that it is going to define hydrostatic pressure loading on a structure. In this case, it is needed to build Calculix from the source!

It will be helpful if there is a similar mechanism for other subroutines such as "dloadd.f".
