Hi Nicolas,
sorry but the ChMatrixNM is in fact missing from the Python wrapper.
There are only two solutions at the moment:
- either you modify the .i files for the SWIG wrapper, adding support
for a 6x6 ChMatrixNM, then rebuild all Chrono and generate the Python
modules (advanced stuff, but I can help). See ChMatrix33.i to understand
how. The trick is mostly in the row
%template(ChMatrix33D) chrono::ChMatrix33<double>;
that in your case could be
%template(ChMatrix66D) chrono::ChMatrixNM<double,6,6>;
- or you switch to C++ , that has a steepy learning curve but in the end
it has less limitations than the Python API
best

Hi !
I want to create a beam model for a wind turbine blade.
I tried to create a ChElasticityCosseratAdvancedGenericFPM with a full
matrix and give it to a ChBuiderBeamIGA but the ChMatrixNM type seems
not to be available in pychrono.
Are there other ways to specify a full stiffness matrix to a beam
section in pychrono ?
Thank you for your help.
Nicolas
